Key Highlights
- Jeff Cavaliere guided Andrew Huberman through a focused biceps and triceps session emphasizing mechanical variations, joint-friendly setups, and stacked movements (incline curls into drag curls) to target long-head biceps development and triceps stretch.
- Practical cues that matter: shift the dumbbell toward the thumb during curls to increase supination loading, avoid low-seated preacher pads that create an elbow fulcrum, perform lying triceps extensions on a bench to maintain range of motion, and turn hands outward on bench dips to protect tendons.
Introduction
A single, well-structured arm workout can expose technique errors, reveal weak links in elbow and shoulder mobility, and deliver a predictable stimulus for muscle growth. Jeff Cavaliere, founder of ATHLEAN-X and one of the most-followed trainers on YouTube, brought those principles into sharp focus when he coached neuroscientist Dr. Andrew Huberman through a direct, science-informed arm session at Gold’s Gym Venice. The set list was compact but deliberate: alternating dumbbell curls, preacher curls, incline curls stacked with drag curls, lying triceps extensions, bench dips, and PJR pullovers.
The session distilled design choices that separate cosmetic arm training from resilient, long-term development. Small adjustments—hand placement, bench positioning, supination mechanics—alter which fibers are recruited and which structures take the load. The following breakdown translates Cavaliere’s coaching cues into a usable roadmap: why each exercise functions, how to perform the movements to minimize risk and maximize stimulus, how to program them across training cycles, and how to modify for different experience levels and common joint limitations.
Why this session matters: exercise selection and intent
Cable curls, preacher curls, and tricep presses populate gyms everywhere, but selection without intent produces inconsistent results. Cavaliere’s approach illustrates four programming priorities:
- Target specificity: choose variations that emphasize the long head of the biceps or the stretch component of the triceps when appropriate.
- Joint safety: prioritize setups that reduce harmful fulcrums and tendon pinching.
- Mechanical sequencing: stack movements so one exercise primes and prepares the muscle for the next (for example, incline curls followed by drag curls as a mechanical drop set).
- Functional overlap: use compound-like isolation work (PJR pullovers) to strengthen multiple structures (lats and triceps) under lower external load.
These priorities guided the workout structure. The exercises are simple, but Cavaliere layered technique and sequencing to extend the effective workload without relying on maximal loads that stress shoulders and elbows.
Exercise-by-exercise breakdown and coaching cues
Alternating Dumbbell Curl
- What it targets: primarily the biceps brachii with emphasis on peak contraction when combined with supination.
- Cavaliere’s cue: shift the dumbbell toward the thumb side of the hand during the curl to increase supination load and create a disproportionate weight vector on the biceps.
- Why it works: supination converts the brachialis’ mechanical advantage to the biceps brachii, especially at the top of the curl. A slight elbow lift toward the finish uses minimal shoulder flexion while preserving arm length tension.
- How to perform:
- Stand tall with feet hip-width apart.
- Start with the dumbbell neutral, palm facing the torso.
- Curl the dumbbell while rotating (supinating) the wrist so the thumb becomes the leading edge.
- Pause briefly at the top to emphasize peak contraction; avoid excessive shoulder shrugging.
- Control the descent to maintain tension.
- Common mistake: swinging the torso or using momentum. Keep the core braced and the elbow relatively stationary. A minimal anterior translation of the elbow at the top is fine; large shoulder flexion converts the movement to an upper-arm raise.
Preacher Curl (seatless variation preferred)
- What it targets: biceps peak in a stabilized environment; isolates elbow flexion.
- Cavaliere’s cue: use a preacher pad without a low seat or a seat that doesn’t force a lever at the elbow. A low seat pushes the elbow into an angle that can create a fulcrum and excessive stress.
- Why it works: the pad stabilizes the humerus and forces the biceps to do the work, reducing cheating. Removing the seat or using a higher seat keeps the upper arm aligned and prevents the elbow from being loaded awkwardly.
- How to perform:
- Position yourself so the pad supports the upper arm against the humerus, not the forearm against a fulcrum.
- Keep the chest tall and avoid sliding forward.
- Curl with controlled tempo, focusing on the eccentric for 2–3 seconds.
- Common mistake: sitting too low or allowing the elbow to jump off the pad. Both reduce isolation and increase stress on the elbow joint.
Incline Dumbbell Curl + Mechanical Drop Set of Drag Curls
- What it targets: long head of the biceps (incline) followed by a mechanical shift to maintain load without changing weight (drag curl).
- Cavaliere’s cue: pair a traditional incline curl with a drag-curl sequence as a mechanical drop set to extend fatigue specifically in the long head.
- Why it works: the incline position lengthens the biceps, emphasizing the long head during the concentric and eccentric phases. A drag curl—where the dumbbell or bar travels up the torso with the elbow traveling posteriorly—changes the line of pull and keeps tension on a different portion of the muscle, allowing continued work as the initial contraction weakens.
- How to perform:
- Set a bench at roughly 45 degrees. Lie back so shoulders are supported and arms hang straight.
- Perform controlled incline curls, maintaining vertical upper arms.
- Immediately follow with drag curls: keep the elbows fixed back toward the torso and drag the DB/bar up along the body, minimizing wrist supination.
- Maintain tight scapular retraction to prevent compensatory shoulder use.
- Common mistake: allowing the elbows to flare forward during drag curls. The point is to move the elbow posteriorly so the biceps maintain tension against the torso.
Lying Triceps Extension (Skull Crushers) on a Bench
- What it targets: triceps long head via a stretched position and a full range of motion.
- Cavaliere’s cue: perform this lying on a bench to preserve a consistent range of motion. Standing variants push the weight forward and shorten the effective triceps stretch for many lifters.
- Why it works: the bench allows the upper arm to extend behind the torso slightly at the bottom, increasing stretch on the long head. Standing variations shift the load anteriorly and reduce the stretch component.
- How to perform:
- Lie on a flat bench with dumbbells or an EZ bar.
- Start with weights over the eyes; lower them toward the temples while maintaining upper-arm position.
- Stop at the point of tension, then extend to lockout focusing on triceps contraction.
- Avoid allowing the wrists to collapse; keep them neutral to reduce strain.
- Common mistake: letting shoulders or upper arms drift forward, which reduces long-head activation and increases shoulder stress.
Bench Dips (hands turned outward)
- What it targets: triceps with bodyweight emphasis and a potential shoulder risk when performed incorrectly.
- Cavaliere’s cue: place hands turned slightly outward to reduce tendon pinching and protect the anterior shoulder structures.
- Why it works: bench dips often place the anterior shoulder into a vulnerable position, especially when the hands are neutral and the body drops too deep. Turning the hands outward rotates the humerus externally, creating more room for soft tissue and preventing impingement.
- How to perform:
- Sit on the edge of a bench with hands placed beside hips, fingers pointing outward slightly.
- Slide hips off the bench and lower until the upper arms are roughly parallel to the floor or to the point of a controlled stretch.
- Push up to full elbow extension without locking aggressively.
- Keep the thorax tall; don’t let the shoulders round forward.
- Common mistake: dipping too low and allowing the shoulders to forward-rotate into a pinching position. If pain occurs, limit range or substitute with triceps machine pushdowns.
PJR Pullovers
- What it targets: a hybrid movement for lats and triceps emphasizing the stretch-contraction continuum without heavy axial load.
- Cavaliere’s cue: use this to strengthen lats and triceps together while maintaining wrist and forearm stability under moderate loads.
- Why it works: PJR pullovers (named after their creator, Pat Robertson) recruit both the long head of the triceps and latissimus dorsi across a large range of motion. Because the movement often uses moderate weights, it allows strength development around the forearm and wrist while emphasizing muscular coordination rather than maximal loading.
- How to perform:
- Lie perpendicular or supine on a bench (depending on variation) holding a dumbbell between both hands.
- Lower the weight behind the head with a slight bend in the elbow, feel the stretch through the lats and triceps.
- Pull back up using a combination of lat extension and triceps push to finish.
- Common mistake: using excessive weight that turns the motion into a shoulder-dominant movement. Keep the load controlled and the tempo deliberate.
Technique principles that change outcomes
The micro-level cues Cavaliere used reflect biomechanical truths that apply across resistance training. Apply these principles consistently and the quality of stimulus, not just the amount of weight lifted, will drive growth while protecting tissue.
-
Line of Pull and Supination: The biceps acts as an elbow flexor and forearm supinator. Slightly shifting the dumbbell toward the thumb during curls increases the moment arm at the top, intensifying tension on the biceps' distal fibers. Supination locks the biceps into a more favorable position for peak contraction.
-
Fulcrum Management: When a machine or seat creates an external fulcrum near the elbow, compression and leverage can overload tendons. Seatless preacher variations or higher seat adjustments stabilize the humerus without creating that mechanical disadvantage.
-
Stretch Under Load: Exercises that place the target muscle under a long-length stretch (incline curls for the biceps long head; lying triceps extensions and PJR pullovers for the triceps long head) evoke structural adaptations in the muscle architecture, including potential increases in fascicle length and sarcomere addition over time.
-
Mechanical Drops and Sequencing: Mechanical drop sets alter the orientation of the limb relative to gravity to continue loading the muscle without changing external weight. They extend time under tension and fatigue new motor units without creating excessive joint stress associated with heavier loads.
-
Tendon-Friendly Positions: Small hand rotations and wrist/forearm alignment drastically affect tendon accommodation. A turned-out hand on bench dips increases subacromial space and reduces anterior shoulder impingement.
These principles should guide exercise choice, not merely replicate movements.
Programming the session: sets, reps, and intensity guidance
Cavaliere’s session favors a mid-volume approach with an emphasis on quality over maximal load. Here is a framework that fits his cues and the exercises performed.
General guidelines:
- Frequency: 1–2 focused arm sessions per week when arms are trained directly; higher frequency possible if volume per session is moderated.
- Set and rep ranges:
- Compound-assist and isolation moves: 3–4 sets per exercise.
- Reps: 6–12 for strength-hypertrophy blends; 8–15 for isolation and stretch-focused exercises.
- Mechanical drop sets: finish one set to near-failure and immediately change the mechanics to continue reps (e.g., incline curl set followed by drag curls).
- Intensity: aim for an RPE of 7–9 on working sets where the last 2–3 reps are challenging but controlled.
- Tempo: control the eccentric (2–4 seconds) and pause briefly at the top for peak contraction work on curls.
Sample session aligned with Cavaliere’s choices (moderate volume)
- Warm-up: 5–8 minutes of general warm-up (row, bike) plus dynamic shoulder and elbow mobility; 1–2 light sets of curls and triceps presses.
- Alternating Dumbbell Curls: 3 sets of 8–10 reps (2–3s eccentric, supinate to emphasize peak).
- Preacher Curl (seatless or adjusted seat): 3 sets of 8–12 reps (2–3s eccentric).
- Incline Dumbbell Curl: 3 sets of 8–10 reps immediately followed by Drag Curls for 6–10 reps (mechanical drop set).
- Lying Triceps Extensions on Bench: 3 sets of 8–12 reps.
- Bench Dips (hands turned outward): 3 sets of 12–15 reps or to technical failure.
- PJR Pullovers: 2–3 sets of 10–15 reps, focusing on stretch and controlled contraction.
Adjustments by level:
- Beginner: Reduce volume to 2 sets per exercise, increase rest between sets to 90–120 seconds, focus on technique and tempo.
- Intermediate: Use the sample session above and add a fourth set to compound moves or add a second arm-focused day with reduced volume.
- Advanced: Implement heavier top sets with lower reps on curls (4–6) and triceps presses, include more advanced intensity techniques (drop sets, rest-pause), and periodize across cycles.
Progression strategies:
- Incremental overload: increase reps first, then load. For curls, aim to add 1–2 reps per set until you reach the upper bound, then increase weight.
- Microloading: use fractional plates or smaller dumbbell jumps to maintain progression without sacrificing form.
- Volume waves: vary weekly volume across 3- to 4-week blocks—higher volume week followed by a deload week.
Managing pain, mobility, and common joint issues
Arm training often exposes elbow and shoulder vulnerabilities. Cavaliere’s cues translate into practical steps to reduce risk:
Elbow tendonitis (common in curls and dips)
- Reduce eccentric overload while tendon is inflamed; perform isometrics and reduce volume to allow recovery.
- Prefer supinated curls with controlled range rather than heavy barbell curls that create repetitive shear.
- Use lighter, higher-rep bench dips or substitute cable pushdowns with neutral grip.
Shoulder impingement with dips and pullovers
- Limit range of motion—stop at the point where the anterior shoulder begins to pinch.
- Turn hands outward on bench dips and keep scapula control throughout.
- For PJR pullovers, keep weight moderate and maintain a slight elbow bend to avoid excessive shoulder extension.
Lack of shoulder mobility for lying triceps extensions
- Use bench support to preserve the required range. If the lifter cannot allow the upper arm to fall behind the torso safely, perform overhead triceps extensions from seated position with limited ROM or controlled cable variations.
Preacher curl discomfort due to seat
- Adjust the seat height or use a standing preacher attachment that eliminates a low seat. Ensure the pad supports the humerus and that the elbow is not exposed to a leverage point that magnifies load on the joint.
Warm-up and recovery
- Perform progressive warm-ups that include light reps for the specific movement patterns to prime the nervous system.
- Foam rolling and mobility work for the pecs, lats, and anterior shoulder can reduce tension and improve access to safe ranges.
- Deload blocks and active recovery weeks reduce cumulative joint stress especially when incorporating high-frequency arm work.
Integrating this arm work into broader training
Direct arm work complements compound upper-body exercises (rows, presses, pull-ups). Use direct sessions after heavy compound days rather than before; pre-exhausting biceps before pulling heavy weights undermines compound performance and increases injury risk. Typical integration patterns:
- Upper/lower split: incorporate the arm session on upper body days following pressing and rowing, or as a dedicated upper-push/pull day.
- Push/pull/legs: perform triceps work after pushing movements; do biceps work after pulling and rows.
- Full-body training: add a pair of direct arm sets toward the end of the session twice weekly, but reduce volume per session.
Example weekly split with Cavaliere-style arm emphasis
- Monday: Upper (focus on pressing) + 2 triceps sets
- Tuesday: Lower
- Wednesday: Rest or light conditioning
- Thursday: Upper (focus on pulling) + Arm workout (complete session as described)
- Friday: Lower
- Saturday: Optional light upper accessory work (rotator cuff, mobility)
- Sunday: Rest
This distribution allows compound lifts to receive priority while ensuring direct arm work receives sufficient volume and recovery.
The science behind mechanical drop sets, stretch-induced hypertrophy, and time under tension
Several mechanisms explain why Cavaliere’s selections promote hypertrophy when applied systematically.
Mechanical drop sets
- Change the mechanical advantage rather than just reduce load. When incline curls convert into drag curls, the biceps remain under tension but along a different length-tension curve. This forces recruitment of accessory motor units and increases metabolic stress without requiring heavier loads.
Stretch-mediated hypertrophy
- Long-length training stimulates sarcomerogenesis and favors increases in fascicle length. Incline curls and lying triceps extensions place the target muscles into greater stretch positions, which research links to structural adaptations distinct from those driven by concentric-only training.
Time under tension and tempo
- Slower eccentrics (2–4 seconds) create microtrauma in muscle fibers conducive to repair and growth, especially when paired with controlled concentric phases and brief pauses at peak contraction. Maintaining tension during the eccentric reduces reliance on momentum and increases metabolic stress across the working muscle.
Motor unit recruitment via posture and angle
- Changing joint angles recruits different regions of the same muscle. For the biceps, supination and elbow position modulate whether the short or long head contributes more. For triceps, overhead or stretched positions emphasize the long head; horizontal pressing emphasizes lateral and medial heads.
These mechanisms complement each other. Applied together in a structured program they improve the quantity and quality of hypertrophic stimulus.
Sample 6-week arm specialization block
This block prioritizes arm growth and borrows Cavaliere’s sequencing philosophy while remaining practical for gym-goers.
Structure: 3 weeks of progressive weekly volume, 1 week deload, then repeat for weeks 5–8 with adjusted loads. Frequency: 2 direct arm sessions per week (Session A stronger on curls, Session B stronger on triceps).
Week 1–3 (Accumulate)
- Session A:
- Warm-up sets
- Alternating DB Curls: 4 x 8–10 (supinate on concentric, 2–3s eccentric)
- Preacher Curl (seatless): 3 x 10–12 (strict tempo)
- Incline DB Curl → Drag Curl mechanical drop: 3 x 8 → 6
- Finisher: Reverse curls 2 x 12–15 (forearm emphasis)
- Session B:
- Warm-up sets
- Lying Triceps Extensions on bench: 4 x 8–10
- Bench Dips (hands out): 3 x 12–15
- PJR Pullovers: 3 x 10–12
- Finisher: Cable rope pushdowns 2 x to failure (light)
Week 4 (Deload)
- Reduce volume by 40–50%, maintain intensity at RPE 6–7 for single sets per exercise, focus on technique and mobility.
Week 5–7 (Repeat with progressive overload)
- Increase working weights by 2–5% or add 1–2 reps per set where possible.
- Introduce one intensity technique per workout: e.g., last set of curls with a 3-second paused contraction, or include a rest-pause set for triceps.
Week 8 (Evaluation)
- Test for changes in 1–3 rep max on heavy curl or measure relaxed arm circumference. Adjust the next block based on recovery and observed progress.
This block maintains recovery through deloading and structured progression, preventing overreach while promoting hypertrophy.
Common mistakes and how to correct them
- Mistake: Relying on ego-driven loads. Correction: Reduce weight until clean form is achieved and muscle connection is obvious. Quality reps beat quantity.
- Mistake: Using a low preacher seat that creates an elbow fulcrum. Correction: Adjust seat height or use a standing preacher attachment.
- Mistake: Letting shoulders dominate hanging triceps work or pullovers. Correction: Reduce load, focus on scapular stabilization and controlled ROM.
- Mistake: Dipping too deep on bench dips. Correction: Establish a safe depth and cue hands turned outward to maintain joint spacing.
- Mistake: No progression plan. Correction: Track reps and loads, use microloading, and implement planned deloads.
Addressing these points increases consistency in gains and reduces cumulative injury risk.
Real-world application: case examples
Case A — Novice lifter with visible underdeveloped triceps A 25-year-old who can bench press 185 lb for 6 reps complains triceps lag behind chest growth. Implement the 6-week block, emphasizing lying extensions and PJR pullovers twice weekly. After four weeks, triceps endurance and shape improve due to higher-volume stretch-loaded work. Bench press assistance also benefits from stronger triceps lockout.
Case B — Intermediate lifter with elbow soreness on preacher curls A 32-year-old experiences medial elbow irritation during preacher curls. Adjust seat height or switch to an incline curl that reduces elbow fulcrum creation. Substitute with cable curls and increase eccentric control. Within two weeks, pain reduces and strength returns.
Case C — Athlete seeking peak contraction for biceps A 40-year-old bodybuilder wants improved peak biceps shape. Focus on alternating DB curls with supination and paused top contractions, include drag curl sequenced after incline curls to exhaust long head fibers. Visible peak improves after consistent application and progressive overload.
These examples illustrate how applying the session’s principles—rather than copying movements blindly—yields targeted improvements.
Accessory considerations: grip, forearms, and functional stability
Strong grip and stable wrists increase the effectiveness of curls and pullovers. Incorporate accessory work:
- Farmer carries: build grip strength and elbow stability.
- Wrist curls and reverse wrist curls: address forearm imbalances that limit curling performance.
- Rotator cuff and scapular stabilization work: prevent shoulder compensations that often present as elbow pain during triceps and curl movements.
Functional stability translates to better force transfer and cleaner movement patterns under load.
How often to revisit pure arm specialization
Direct arm specialization blocks work best when applied periodically rather than continuously. Use 4–8 week blocks every 3–6 months depending on goals:
- Off-season hypertrophy focus: 6–8 week block every 3 months.
- In-season strength athletes: 4-week microcycles with low volume but higher intensity.
- General fitness: 4-week cycles twice per year for maintenance and progression.
Adjust based on recovery, training priorities, and competition calendar.
Measuring progress beyond the mirror
Use objective and subjective markers:
- Strength: increase in reps or load on core movements (incline curl, triceps extension).
- Volume capacity: ability to complete planned sets with less perceived exertion.
- Circumference measurements: relaxed arm circumference taken consistently.
- Functional improvements: better lockout strength in pressing movements and reduced elbow pain.
Combine quantitative tracking with regular subjective assessments of recovery and joint comfort.
Putting it together: a practical checklist before each arm session
- Perform a brief general warm-up and specific warm-up sets for curls and triceps.
- Inspect bench and preacher pad heights; adjust to neutralize any fulcrum effects.
- Choose loads that allow controlled eccentrics and maintain supination cues on curls.
- Sequence incline curls into drag curls to exploit mechanical drop set benefits.
- Keep dips shallow enough to avoid pinching and turn hands outward for tendon protection.
- Finish with PJR pullovers for coordinated lat-triceps strength under moderate load.
- Monitor RPE and stop before form collapses.
Follow this checklist to maximize the intended stimulus and reduce unnecessary strain.
FAQ
Q: How many times per week should I train arms directly? A: For most lifters, once per week with moderate volume produces gains. Two sessions can be effective if volume per session is adjusted and recovery is sufficient. Beginners should start with one focused arm workout every 7–10 days while prioritizing full-body compound lifts.
Q: Are mechanical drop sets better than traditional drop sets? A: Both are effective. Mechanical drop sets maintain external weight but change leverage or joint angle to continue loading the muscle. They often preserve joint comfort compared with rapid weight reductions and allow specific fiber recruitment. Use whichever method lets you maintain form and tension.
Q: I feel elbow pain during preacher curls. Should I stop them? A: Not necessarily. First adjust seat height or perform the same movement from a standing preacher attachment that prevents elbow fulcrum creation. If pain persists, substitute with incline curls or cable curls to reduce joint stress while maintaining stimulus.
Q: Can I replace bench dips with cable pushdowns? A: Yes. Cable pushdowns provide similar triceps loading with potentially less shoulder stress. Keep hand orientation and elbow position in mind to match the desired head emphasis.
Q: How important is supination in curls? A: Supination shifts force onto the biceps brachii and increases peak contraction. Slightly rotating the dumbbell toward the thumb on the concentric enhances this effect. Avoid over-rotating to the point where wrist strain occurs.
Q: Do PJR pullovers build lats or triceps more? A: They train both. The movement places the lats under a stretch while the triceps assist through the extended position. Use moderate load and emphasize the stretch and coordinated contraction rather than maximal weight.
Q: How soon will I see arm growth from this type of program? A: Noticeable changes can appear in 6–12 weeks with consistent progressive overload, adequate nutrition (sufficient protein), and recovery. Individual timelines vary based on training history, genetics, and overall program adherence.
Q: Should I do heavy curls for strength and lighter higher reps for shape? A: Both approaches contribute. Heavy curls (4–6 reps) increase strength and recruit high-threshold motor units. Moderate rep ranges (8–12) and higher reps (12–15) increase metabolic stress and time under tension, benefiting hypertrophy and endurance. Mix rep ranges across cycles.
Q: Are there specific mobility drills to help with lying triceps extensions and PJR pullovers? A: Thoracic mobility drills, latissimus stretches, and anterior shoulder mobility work improve access to the extended positions. Controlled banded dislocations and doorway lat stretches help prepare tissues for safe ROM.
Q: What should I do if I plateau? A: Reassess load progression, volume, and recovery. Implement a deload week, change one variable (tempo, rep range, exercise order), and consider introducing mechanical drop sets or paused reps to break the plateau.
The Gold’s Gym session between Jeff Cavaliere and Dr. Andrew Huberman demonstrated that thoughtful adjustments to familiar movements produce measurable changes in stimulus and joint stress. Small technique choices, properly sequenced exercises, and a consistent progression plan deliver growth while protecting key structures. Apply the cues, program with intention, and measure progress with objective markers to convert that single session’s logic into lasting arm gains.
