Key Highlights

• A structured, capacity-focused workout centered on individual medley (IM) work prepares 13–22-year-old swimmers for a meet in three weeks; includes warm-up, main IM/aerobic sets, and a short high-intensity finisher.
• Progressive three-week plan: two weeks of targeted capacity and race-pace introduction followed by a controlled taper week; clear scaling guidelines for age groups and performance levels.
• Practical coaching cues, pacing targets, dryland protocols, nutrition priorities, and sample adjustments for pool length or injury recovery.

Introduction

Three weeks before a target meet, training must thread a narrow needle: maintain and extend aerobic capacity while preserving speed and freshness. Coaches who prioritize capacity at this stage build physiological resilience—more efficient oxygen delivery, improved lactate clearance, and stronger race repetition—without forcing exhaustive, race-specific work that risks fatigue. For teams training in 25-meter pools and for swimmers aged roughly 13–22 at high-school, national, or collegiate levels, one well-designed IM session per week delivers technical variety, balanced energy-system development, and mental engagement.

The following plan and workout expand on a coach’s concise brief: base-building emphasis, at least one IM session weekly, and a satisfying finisher to close practice. The material translates that brief into actionable sets, pacing prescriptions, dryland and recovery guidance, and a three-week progression toward race day. Use the provided session as a template or integrate individual pieces into an existing program.

Why prioritize capacity three weeks out?

Capacity training at three weeks before a meet focuses on raising the ceiling rather than forcing immediate peak performance. Physiological adaptations targeted here include mitochondrial density, capillarization, and improved stroke efficiency under sustained effort. Practically, that translates to:

• Cleaner technique when under fatigue, especially through transitions in IM races.
• Greater repeatability of race-pace efforts during rounds and relays.
• Lower injury risk during the taper phase because athletes have a larger aerobic base to metabolically support sprint work.

Younger athletes (13–14) respond well to volume and variety with slightly reduced intensity, while older athletes (19–22) can handle higher volumes and sharper intervals. For both groups, IM sessions force proficiency across fly, back, breast, and free—and that technical spread keeps sessions engaging while developing complementary muscle groups.

A coach’s single IM session per week can cover technical, aerobic, and race-specific elements in one practice if it is structured thoughtfully. This session should blend steady aerobic repetition, broken IM sets to emphasize transitions, and short, high-intensity closures to stimulate neuromuscular readiness.

Session overview: intent and setup for a 25-meter pool

Purpose: Capacity (base) building with IM emphasis.
Pool: 25 meters.
Target swimmers: 13–22 years old, high school state to collegiate level.
Weeks until target meet: 3.

Session objectives:

• Reinforce stroke mechanics across all four strokes in an aerobic context.
• Extend threshold capacity through sustained, controlled efforts.
• Introduce short race-pace elements without causing full fatigue.
• Finish with a satisfying high-energy finisher to stimulate speed and grit.

General session length: 75–95 minutes in the water, depending on warm-up and cooldown length. Dryland optional before or after the pool session for activation or strength maintenance.

Equipment suggestions: fins (for technique-focused segments), pull buoy, paddles (light use to emphasize tempo rather than brute force), tempo trainer if available, kickboard, snorkel for stroke-specific focus.

Warm-up, main set, finisher, cooldown: the core architecture. Each piece should connect to the next: the warm-up primes technique, the main set develops capacity while embedding IM transitions, and the finisher preserves speed.

Warm-up and early technical work: priming stroke balance and pacing

A focused warm-up remains the highest-return part of the practice. The goal here is to activate all strokes, reinforce fundamentals for turn and transition efficiency, and establish an aerobic baseline.

Example warm-up (approx. 800–1,000 meters):

• 400 easy swim (4 x 100): build through each 100—first 25 easy, second 25 drill, third 25 swim with focus, fourth 25 strong kick (alternate strokes each 100 to cover all strokes across set).
• 4 x 50 drill-swim: 25 drill / 25 swim on 10–15s rest. Rotate strokes across the 50s: fly, back, breast, free. Use a snorkel for one 50 to maintain head position.
• 4 x 25 (fast pick-up): 25 build to 90% from a controlled start on 20s rest—alternate strokes. Focus: clean breakout and tempo.
• 200 kick (choice): with or without fins depending on age and focus. Pull buoy optional but avoid excessive paddles early in warm-up.

Coaching cues:

• Keep hips high on backstroke and freestyle kick sets—low hips amplify drag early in the set and compound fatigue.
• Emphasize smooth transitions in IM turns; the 3–1 timing is crucial for breast-to-free and fly-to-back transitions.
• If a swimmer struggles with one stroke during warm-up drills, assign a short drill progression (e.g., 4 kicks + 4 technique strokes in a 25) immediately after to correct the pattern.

Warm-up length can be shortened for younger age groups to preserve energy for the main set: reduce 400 to 300 and adjust remaining volume proportionally.

Main set: building aerobic capacity through IM-centric progressions

The main set is the engine of this session. It combines steady aerobic repetitions with broken pieces that challenge IM transitions and introduce controlled speed. Two complementary approaches work well depending on the group's size and the coach’s emphasis: (A) continuous IM-focused repeats for endurance; (B) broken IM sets with pieces that simulate race stresses.

Main Set A — Continuous IM Repeats (session template for 13–22s)

• 3 x 400 IM on 1:00–1:20 rest beyond expected swim time (for example, if swimmer’s 400 IM pace is 6:00, send on 7:00). The objective: steady aerobic pace, controlled stroke rate, clean turns.
• 6 x 200 IM on interval (rest adjusted to keep effort aerobic): first 3 at aerobic steady pace (~70–75% race effort), last 3 slightly faster but controlled (75–85%).
• 8 x 50 IM order descend 1–4 or rotate strokes: first 4 focus on stroke-specific form (descend 4 counts), second 4 pick up the pace to 90% with 15–20s rest.

Main Set B — Broken IM and Threshold Development (recommended for teams aiming for threshold gains)

• 4 x 300 broken IM: 100 swim steady / 4 x 50 IM (25 drill/25 swim) on short rest / 100 swim. Send on an interval that permits ~15–20s rest between repeats.
• 6 x (3 x 100 IM broken as 25/25/25/25 with 10–15s between the 100s) with 30s rest between groups. First group: aerobic steady. Second: threshold feel. Third: near-threshold with controlled finishing speed.
• 12 x 50 stroke-specific at threshold intensity: 4 fly/back/breast/free with 20–25s rest—focus on maintaining stroke mechanics as fatigue accumulates.

How to choose between A and B:

• A is straightforward and covers sustained aerobic work, ideal when pool time is limited or swimmer fatigue is present from recent heavy training.
• B introduces more neuromuscular challenge and simulates race transitions; it produces greater lactate stimulus and better prepares swimmers to hold technique under stress.

Pacing guidance:

• Aerobic steady: conversational but purposeful; maintain form. Aim for ~70–80% perceived exertion.
• Threshold repeats: sustainable but challenging; roughly the pace a swimmer could hold for 20–40 minutes in a continuous swim test, or repeatable 200–400 efforts at elevated effort.
• Race-pace introductions: short pieces at 90–100% to cue neuromuscular patterns without draining buffers.

Interval math: For a 25m pool, set intervals so athletes get 10–30s rest depending on level. Example: 200 on 3:30 for high-school athletes might include a target of 2:50–3:10 and yield moderate rest; collegiate athletes may require tighter rest windows.

Real-world application:

• A high-school state team used Main Set B three weeks before states and reported more consistent IM finishes; swimmers who practiced broken IM segments improved transition efficiency and under-pressure control in finals.
• A collegiate program preferred continuous repeats (A) to extend aerobic base while inserting short race-pace fly pieces mid-week and during taper.

Technique-focused broken drills and transition work

IM races live and die in transitions: the end of fly into back, and breast-to-free breakout. The main set must include targeted drills that isolate those transitions.

Transition drill examples:

• Fly-to-back: 6 x 25 from push on fly, focus on last two kicks and a clean rollout into backstroke—use a tempo trainer to control tempo cadence for the fly 25s.
• Back-to-breast: 6 x 25 drill-swim: 25 backstroke with exaggerated rotation and controlled arms into a 25 breast glide focusing on timing of pull and kick.
• Breast-to-free: 6 x 50 broken: 25 breast kick with glide / 25 free strong breakout.

Fractional and broken IM work:

• Broken 200 IM: swim 100 steady then break 100 into 4 x 25 (each stroke) on minimal rest to emphasize repetition under partial fatigue.
• 4 x 75 (25 fly/25 back/25 breast) with 20s rest then swim 25 free hard—this simulates the effort spike at the end of IM events.

Coaching cues:

• Encourage swimmers to focus on breakout speed and controlled acceleration, not excessive power that increases drag.
• Use underwater video where possible to show mismatches between perceived and actual breakout timing.
• For breaststroke, emphasize glide length and chest alignment to preserve energy for the free leg.

Finisher: short, sharp, and satisfying

Finishers close training sessions by activating fast-twitch systems without large metabolic cost if kept short. Choose a finisher that reinforces race skills, builds psychological toughness, and leaves swimmers energized rather than exhausted.

Three finisher options:

1. Sprint IM finisher (technical + speed)

• 8 x 50 IM order: first 25 moderate, second 25 sprint from a push or dive, 20s rest. Focus on perfect turns and explosive breakouts. Total time: ~10 minutes.

2. Race-pace repetition (neuromuscular primer)

• 6 x 25 on :45–1:00 at 100% from a 3–5 second dive start. Rotate strokes or set to swimmer’s primary races. Encourage full finishes and aggressive breakouts.

3. Controlled lactic shock (for older swimmers)

• 4 x (50 fast / 25 easy) on 1:30. Maintain high speed on the 50s but allow short recoveries to promote recovery kinetics.

Why finishers matter:

• They sharpen speed without heavy volume.
• They train the body to 'turn on' quickly during meets after long rest periods.
• They create a sense of accomplishment; the psychological element of finishing well can translate into confidence on race day.

Coaching note: For younger swimmers (13–14), choose finishers 1 or 2 with smaller total reps and slightly longer rest. For collegiate or national-level swimmers, consider finisher 3 with tighter rest to maintain a competitive edge.

Cooldown and recovery strategies

A purposeful cooldown accelerates recovery, flushes metabolic byproducts, and reinforces technique at low intensity.

Cooldown example:

• 200 easy swim choice with emphasis on long, smooth strokes.
• 4 x 50 drill/swim descending from 40% to 75% intensity with 15s rest.
• 100 easy kick or choice to settle core temperature.

Active recovery between high-intensity efforts is critical. Encourage swimmers to perform light mobility or foam rolling after exiting the pool and to hydrate immediately. If pool time or logistics prevent a long cooldown, prioritize at least 5–8 minutes of low-intensity swimming and poolside stretching.

Post-practice recovery:

• Immediate carbohydrates + protein (within 30–45 minutes): a 3:1 or 4:1 carb-to-protein ratio helps replenish glycogen and repair muscle.
• Compression or contrast baths (cold/hot) can be useful for some athletes; apply conservatively and personalize according to response.
• Sleep quality remains the single strongest recovery driver; encourage regular sleep schedules during this three-week block.

Dryland: preserve strength and support stroke resilience

Dryland sessions during this capacity-focused block should maintain strength and power without creating undue systemic fatigue. Two 20–35 minute sessions per week suffice, one focused on activation and mobility and the other on strength maintenance.

Sample dryland session A — Activation and mobility (20–25 minutes)

• 5 minutes dynamic warm-up: lunges, leg swings, arm circles, band walks.
• 3 rounds:
  • 10 single-leg RDLs (bodyweight or light dumbbell)
  • 10 push-ups (or banded chest press)
  • 8-10 scapular pull-ups (emphasize lower trapezius engagement)
  • 30s plank with alternating arm reach
• 5 minutes static mobility: thoracic rotation, hip flexor stretch.

Sample dryland session B — Strength maintenance (30–35 minutes)

• Warm-up 5 minutes.
• 4 rounds:
  • 6–8 goblet squats
  • 6 Romanian deadlifts (moderate weight)
  • 6–8 single-arm dumbbell rows each side
  • 8 shoulder presses (light–moderate)
• Core circuit: 3 x 30s hollow hold / 30s side plank each side.

Coaching considerations:

• Tailor load based on training age; heavier loads for collegiate athletes, bodyweight or light loads for younger swimmers.
• Emphasize posterior chain and scapular stability—these support stronger pull mechanics and reduce shoulder injury risk.
• Avoid high-volume eccentric loading in the week immediately before taper; residual muscle damage carries into the meet.

Sample three-week progression: building, sharpening, tapering

This three-week template converts the single session model into a broader practice schedule. It assumes a typical team training schedule of 5–6 sessions per week. Adjust volume and intensity according to your program’s baseline.

Week 1 — Build (Days 1–7)

• Purpose: raise aerobic threshold and reinforce IM technique.
• Key sessions: One IM-focused capacity session (the one detailed above), two longer aerobic swims (e.g., 5,000–6,000m total with variable intensity), two technique/speed sessions with shorter race-pace reps, and one recovery swim.
• Dryland: Two short sessions (activation + strength maintenance).
• Example weekly highlight: Monday IM capacity session; Wednesday threshold repeats; Friday race-pace sprints.

Week 2 — Intensify (Days 8–14)

• Purpose: introduce controlled race-pace exposures while maintaining aerobic stimulus.
• Key sessions: One IM session with slightly faster target paces in last third, one lactate-targeted session (broken 100/200 pieces at threshold), two sprint/race-pace sessions with starts and turns practice, one medium aerobic day.
• Dryland: One strength maintenance session, one mobility session.
• Volume: Slight increase in intensity with similar or marginally increased volume compared to Week 1.

Week 3 — Sharpen and taper (Days 15–21)

• Purpose: shift toward freshness while keeping feel for speed and start/turn execution.
• Key sessions: One short IM session with less volume but crisp race-pace work (e.g., reduced to 60% of the previous IM session volume with targeted fast 25s and 50s), two short sharp sessions focusing on sprint mechanics and relay takeovers, increased rest days or active recovery sessions, one light aerobic swim.
• Dryland: Light mobility and activation only; no heavy strength sessions.
• Hydration, sleep, nutrition prioritized; reduce overall training load 30–50% depending on athlete.

Example timeline for a swimmer specializing in 200 IM:

• Week 1: 2 IM-focused swims (long aerobic IM + broken IM), heavy technique work on transitions, heavy aerobic volume.
• Week 2: One intense IM session with controlled race-pace pieces (e.g., 4 x 200 @ 200 race pace with full rest), sharpen starts and turns.
• Week 3: Reduce training volume; include 2–3 race-pace touch-ups (short sprints), emphasis on mental rehearsal and race strategy.

Adjustments for meet schedule: If meet starts mid-week, manipulate taper distribution so the final high-intensity touchpoint is 5–7 days before the first race for optimal freshness.

Pacing specifics: translating best times into interval targets

Pacing must be concrete, not just perceived effort. Provide swimmers with explicit targets and how to calculate them.

How to set paces:

• Use recent best times for 100/200 distances as benchmarks. If a swimmer lacks recent times, use time trials or training test sets to estimate threshold and race pace.
• Aerobic steady repeats: aim for 10–20 seconds slower than 200 race pace per 200.
• Threshold: within 3–5 seconds per 100 of target 400/800 pace (or the pace they could sustain for roughly 20–30 minutes).
• Race-specific 50s/25s: at or slightly faster than race pace for that stroke; on short rest for neuromuscular priming.

Example for a swimmer with a 200 IM best of 2:00.00:

• Aerobic steady 200s: target 2:10–2:20 range.
• Threshold 200s: 2:02–2:06 pace.
• Race-pace 25s and 50s: targeted splits between 14–16s for 25s or 30–35s for 50s depending on stroke and race phase.

Use tempo and stroke-rate tools:

• Implement a tempo trainer for fly and free pace control; measure stroke count per 25 to monitor efficiency.
• Measure stroke count and time on 50s; a stable or slightly reduced stroke count with faster time indicates improved power per stroke.

Managing intervals:

• For aerobic repeats, provide ample rest to keep stroke quality high. 10–30s rest is appropriate; younger swimmers benefit from the higher end of that range.
• For threshold repeats, tighten rest to 15–20s for older athletes; allow 20–30s for younger ones.
• For race-pace sprints, include full recovery when needed (e.g., 2–3 minutes for near-max 50s) to prevent form degradation.

Individualization: age groups, experience, and event specializations

Not all swimmers on the deck have the same needs. Here’s how to tailor the session to specific profiles.

Younger swimmers (13–14)

• Reduce total volume by 20–30% relative to older age groups.
• Keep intensity moderate; emphasize technique and motor learning.
• Allow longer rest in fast sets and prioritize variety to maintain engagement.

Mid-teen swimmers (15–18)

• Follow the full session but monitor fatigue across sessions. These athletes adapt quickly and can handle both aerobic and threshold stress.
• If the swimmer specializes in a single stroke (e.g., 200 fly), add extra fly-specific repetitions but maintain IM balance to prevent overuse.

Older swimmers / collegiate (19–22)

• Increase volume and tighten rest windows for threshold and race-pace work.
• Introduce more complex broken sets and higher intensity finishers.
• Use data (heart rate, lactate where available) to refine interval adjustments.

Sprinters vs distance specialists

• Sprinters: shorten the aerobic components and replace part of the main set with shorter, higher-intensity efforts; maintain IM work but bias toward fast, technical pieces.
• Distance specialists: emphasize the longer aerobic repeats in the main set and use finishers sparingly; keep some race-pace touchpoints to maintain turnover.

Accounting for injury or shoulder sensitivity

• Substitute pull/paddle work with pull with snorkel or limit paddles; emphasize high-elbow catch and scapular activation.
• Replace fly with underwater dolphin kick and technical drills if fly causes discomfort.
• Use shorter sets and more rest to manage local fatigue.

Monitoring and coaching cues: how to read the session

Real-time monitoring and minor adjustments make a good set great. Watch for these signals:

Positive indicators:

• Controlled stroke counts with maintained or slightly improved times across repeats.
• Crisp transitions in IM turns without deceleration.
• Strong breakouts from walls and consistent pace maintenance.

Warning signs:

• Increasing stroke counts with slowed times—sign of fatigue and form loss.
• Uneven times across stroke segments (e.g., breast slows dramatically in IM)—indicates a technical weakness that needs immediate attention.
• Excessive gasping or vomiting—stop and reassess load.

Adjustment toolkit:

• Reduce interval intensity or add 10–20s rest if stroke quality degrades.
• Split the set into shorter pieces with short rest to maintain pace without total effort increase.
• Have a quick technical micro-drill (e.g., 50s focusing on one transition) between repeats to re-engage motor patterns.

Real-world coaching anecdote: One club noticed consistent slowdown in breaststroke during 200 IM sets. Coaches inserted 2–3 targeted breast technique sessions across the week and replaced some high-volume pull to rest the shoulders. Within ten days, swimmers reported more even splits and smoother transitions—evidence that small, targeted corrections produce outsized gains.

Nutrition and sleep: what to prioritize during the three-week block

Performance depends just as much on recovery inputs as training design. During this three-week window, prioritize:

Daily nutrition

• Maintain consistent carbohydrate intake to support glycogen stores; complex carbs with each meal.
• Protein intake distributed across the day; aim for ~1.4–1.8 g/kg bodyweight during heavy training phases.
• Hydration: monitor urine color and body weight pre/post training; a 1–2% bodyweight loss during practice warrants focused rehydration.

Pre- and post-training

• Pre-session: small carbohydrate snack 30–60 minutes before practice if energy is low (e.g., banana, energy bar).
• Post-session: quick-absorbing carbs and 20–30g protein within 30–45 minutes. Chocolate milk is a practical option for many teams.
• For morning lifts or heavy sessions, include protein + carb within that immediate window and a fuller recovery meal within 2 hours.

Sleep

• Aim for 8–10 hours per night for adolescent athletes; at least 7–9 for older athletes.
• Maintain consistent sleep schedule; avoid late-night screen use before bed.
• Implement naps (20–40 minutes) for swimmers who need additional daytime recovery.

Supplementation: consider a multivitamin, omega-3s for inflammation control, and vitamin D if levels are low. Use supplements under supervision; avoid stimulants or high-risk supplements close to competition.

Using Commit Swimming and swim-tech tools for tracking

Commit Swimming provides a simple platform to share this session and track attendance, set data, and athlete notes. Use these tools to:

• Distribute workouts in advance so swimmers arrive mentally prepared.
• Record interval adherence and times for future pacing calibration.
• Tag recurring problem areas (e.g., breast transition) for targeted correction in subsequent sessions.

Additional tech:

• Tempo trainers and video can provide objective feedback on stroke tempo and breakout timing.
• Heart-rate monitors give insight into internal load; use them to prevent excessive cumulative stress during build weeks.

Example practice script for coaches (verbal cues and time checks)

A deliberate coaching script helps practices run smoothly, especially with large groups.

Before practice

• "Set goals for today's session: clean IM transitions and maintain a controlled aerobic pace in the main set. Look for smooth breakouts and a stable stroke count."

Warm-up cues

• "On those drill 50s, exaggerate your kick on fly and feel your hips rise. Backstroke: long, relaxed arms on the early part of the stroke."

Main set cues

• "Aim to hold technique for the first 75% of each 200; pick up tempo only on the last 25 meters if you can."
• "On the broken 100s, make your step-downs controlled—do not spike too early. Keep the last 25 of each repeat focused and aggressive."

Finisher cues

• "Short sprint here—full finish off each wall. Leave everything in lane but swim smart."

Post-practice

• "Hydrate, get a mix of carbs and protein, and note any stroke discomfort in the team log. Tomorrow is an active recovery—plan for good sleep tonight."

When to modify or skip the IM session

Modify the session if:

• Multiple swimmers report illness or elevated baseline HR—reduce volume and intensity.
• Meet schedule places heavy races within 48 hours—replace this session with a short race-pace touch-up.
• The team has had an unusually high training load in the previous week—opt for a lighter, technique-biased session.

Skip or heavily modify for:

• Sudden increases in injury reports (shoulder, knee) across the squad.
• Extreme environmental conditions (pool water temperature, air quality) that jeopardize safety.

FAQ

Q: How should this session change for a 50m pool? A: Double the distance of repeats to keep set density similar (e.g., 4 x 200 in a 25 becomes 4 x 200 still, but adjust intervals because flip-turn patterns change). Alternatively, keep distances but increase repetitions to maintain work volume. Factor in longer swim times for 50m laps and correspondingly adjust rest windows to preserve stroke quality.

Q: How do I scale the workout for younger swimmers who aren't comfortable with 400s or long IM sets? A: Reduce repeat distances and increase rest. For example, swap 3 x 400 IM for 4–6 x 200 IM with 30–45s extra rest per repeat, or replace some 200s with 100s focusing on technical execution. Emphasize variety to maintain engagement.

Q: How exactly do I calculate target intervals based on race times? A: Use recent bests. Example: If a swimmer's 200 IM best is 2:00, aerobic 200s could be 2:10–2:20 with 15–30s rest; threshold 200s aim close to 2:02–2:06 with tighter rest; race-pace 50s and 25s should align with splits from their best times (divide time by appropriate count and add/subtract seconds according to stroke and fatigue).

Q: When should I include starts and turns practice relative to this session? A: Integrate starts and turns during the warm-up or at the end of the main set prior to the finisher when athletes are still relatively fresh. Reserve high-quality starting practice and full-dive 25s for the sharpening/taper week to avoid start fatigue earlier in the block.

Q: How often should IM-focused sessions appear during a week? A: One solid IM-focused capacity session per week is sufficient for balanced progression while preserving energy for stroke-specific work. Depending on team size and specialization, add one complementary session emphasizing sprint transitions or stroke-specific repeats.

Q: What's the best way to rehabilitate an athlete returning from a minor shoulder issue during this block? A: Prioritize technique, reduce pull volume, avoid paddles initially, and limit high-volume fly/power sets. Incorporate scapular-stability drills and gradual exposure to resistance. Coordinate progression with medical staff or physiotherapist.

Q: How much total yardage/meters should each age group aim for in the session? A: For 25m pool metres: younger swimmers (13–14) ~2,500–3,000m total; mid-teen athletes (15–18) ~3,500–4,500m; collegiate (19–22) can range from 4,000–6,000m depending on the program. Adjust for session intensity and the overall weekly plan.

Q: What metrics should coaches track to evaluate effectiveness? A: Track stroke counts, interval adherence, split stability across repeats, perceived exertion, and recovery markers (resting HR, sleep quality). Periodic test sets (e.g., 400 time trial or lactate tests where available) give objective progress data.

Q: How do I maintain motivation through a three-week block that includes lots of aerobic work? A: Keep variety in sessions, use IM to alternate stroke emphasis, insert short, satisfying finishers, and set clear micro-goals each practice (e.g., “nail five perfect IM transitions” or “hold stroke count under X for the last 100”).

Q: Should swimmers do dryland immediately before or after this session? A: Preferably after lighter pool sessions or on separate days for heavy strength work. Short activation work (10–15 minutes) before the pool helps warm up, but full strength sessions should be scheduled when pool intensity is lower, typically not on the day before a key race.

This plan converts a concise coaching brief—IM once per week, capacity focus, small finisher—into a full, actionable three-week progression for teams training in 25m pools. Adjust volumes, rest, and drill emphasis by age and training age. The most effective sessions preserve technique under steady stress while leaving room for speed and freshness as meet day approaches.
