Key Highlights:

• Jonathan Lucroy pushed back after the Kelce brothers said baseball players don’t need cardio, arguing Major League Baseball’s daily schedule and positional demands create a unique endurance requirement.
• Lucroy cited pitchers running poles and catchers performing hundreds of squats per game as evidence that baseball conditioning emphasizes sustainable volume and recovery rather than one-off high-intensity sessions.
• The debate underscores a broader misunderstanding: conditioning must match a sport’s rhythm—baseball prioritizes repeated, submaximal efforts and longevity across a 162-game season, while football trains for infrequent, highly physical collisions.

Introduction

A clip from the Kelce brothers’ New Heights podcast landed in the middle of a long-running debate about sport-specific training. Jason Kelce dismissed traditional cardio for baseball players—“There’s zero cardio necessary to be a good baseball player”—and Travis backed him with a high-school memory of running from foul pole to foul pole. Jonathan Lucroy, a former MLB catcher, replied bluntly: baseball is not easy in the way the Kelces described, because players do something very different from football athletes. The exchange highlights how calendar, position and competition frequency shape the kind of conditioning each sport demands. What looks like “no cardio” from the outside is often a deliberate, season-long approach to managing workload and preserving performance.

The argument is not about which sport is harder. It is about specificity: different games require different physiological profiles and training philosophies. Lucroy’s rebuttal offers a useful lens to examine how baseball players prepare, how their workouts differ from football routines, and why casual statements about “no cardio” misread the daily realities of a seven-month season.

What Jonathan Lucroy Said — and Why It Resonated

Lucroy’s reaction was direct and precise. He responded on X after hearing the Kelce brothers’ episode, emphasizing that baseball players play nearly every day, and that reality dictates how they train.

Jason Kelce had stated, “There’s zero cardio necessary to be a good baseball player.” Travis offered a supporting anecdote from high school about sprinting foul-pole to foul-pole. Lucroy pushed back with specific examples. He noted, “The pitchers run poles to endure longer outings. Nolan Ryan did them every day.” He also described position-player conditioning: “Position players run bases for conditioning in Spring Training. During the season, we don’t do much conditioning as an everyday player. Why? Because we play almost EVERYDAY.” For the catcher’s perspective he added a striking workload estimate: “That means I did at least 200 squats every game,” and extrapolated to roughly 24,000 squats across a 120-game stretch.

Those numbers and anecdotes resonate because they reveal the underlying logic. Conditioning in baseball is largely about sustaining capacity and resisting cumulative fatigue. The daily nature of the schedule, frequent travel and repetition of specific movements require a different approach than the once-weekly cadence of football.

The exchange also underlines a communication gap. High-profile athletes with big audiences can shape public ideas about training. The Kelce brothers’ comments reflected what many non-baseball observers assume: that baseball is a series of discrete, low-intensity actions that require little formal cardio. Lucroy’s reply reframed the conversation as one about volume, micro-recovery and sport-specific conditioning.

How the MLB Calendar Shapes Conditioning: 162 Games, Travel and Attrition

A professional baseball season is long by design. MLB teams play 162 regular-season games spread over roughly six months, not counting spring training, postseason play or off-season development. Football, by contrast, fields 17 regular-season games. That difference alters everything from practice structure to weekly load management.

When a player suits up almost every day, training priorities shift from maximal, short-term gains to sustainable maintenance. Workouts are scheduled around games, with spring training serving as the primary window for intense conditioning. During the regular season, coaches and strength staff aim to preserve functionality and reduce injury risk. The game itself becomes the most significant conditioning stimulus.

Travel compounds the challenge. Road trips, varying hotel conditions, and changing time zones affect sleep and recovery. Teams build routines to stabilize circadian rhythms and maintain performance metrics, but daily games reduce the margin for recovery. When a series includes four consecutive days of games, the emphasis becomes small decisions—what to lift, what to skip, when to do an active recovery session. Over months, those small choices determine whether a player endures a full season or succumbs to wear and tear.

That marathon structure explains why baseball conditioning differs: the objective is to remain available and effective across hundreds of discrete decisions—pitches, swings, throws—rather than to peak for a single explosive performance.

The Catcher's Workload: Squats, Crouches and Accumulated Stress

A catcher’s day is deceptively demanding. Behind the plate, the position requires repeated squatting, quick lateral movements, blocking, throws to bases and constant mental workload. Those physical demands add up.

Lucroy’s claim of “at least 200 squats every game” provides a useful illustration. Whether by literal counted squats during warmups, rhythm-based movements between innings, or the functional equivalent of switching repeatedly into a squatting position, catchers sustain cumulative eccentric and concentric load in the quadriceps, glutes and hips. Multiply that by 120 games and the mechanical load becomes enormous.

Beyond squats, catchers absorb impact when blocking balls in the dirt, execute fast-twitch throws to second base, and maintain posture and focus inning after inning. Recovery is therefore a combination of active mobility, soft-tissue care, and workload modulation. Teams prescribe restorative sessions—contrast baths, targeted soft-tissue work, light aerobic flows—that help players maintain range of motion and reduce stiffness between games.

Catchers who last into their late 30s and 40s typically manage these loads carefully. Some shift throwing mechanics, refine framing and block more efficiently to reduce stress. Others alter their workload by taking extra days off, splitting catching duties, or adjusting throwing programs.

Lucroy’s numbers make the point plainly: what might look like limited cardio on the surface is actually a continuous, high-volume mechanical challenge that calls for endurance of a specific type—muscular endurance and recovery capacity more than long, continuous runs.

Pitchers and “Poles”: Traditional Conditioning and Modern Nuance

The image of pitchers running foul-pole to foul-pole—referred to by Lucroy as “running poles”—harks back to classic conditioning practices. For many pitchers, especially in previous eras, long-distance runs or repeated submaximal efforts were part of building the ability to endure longer outings.

Lucroy referenced Nolan Ryan, noting that Ryan ran poles regularly. Ryan’s career longevity and late-career velocity make his routine an oft-cited example for endurance conditioning. The logic is simple: if a pitcher is expected to throw many innings per outing, they need a metabolic base that supports prolonged muscular effort, efficient recovery between innings, and consistent velocity across multiple frames. Running poles and long-baseline conditioning were one method to create that base.

Modern pitcher conditioning has evolved. Long toss programs, structured bullpen sessions, pitch counts, innings limits and biomechanics analysis now govern how workloads are built. The goal remains similar: create a body that can tolerate repeated, high-intensity contractions across a multi-month campaign. But teams now measure workload more precisely, tracking throwing volume with wearable tech, monitoring RPE (rate of perceived exertion), and programming recovery windows between starts.

Pitchers who transition from starter to reliever often change conditioning strategies. Starters focus on stamina and the ability to maintain performance across several innings. Relievers concentrate on shorter, higher-intensity efforts and rapid recovery. That continuum highlights one lesson from Lucroy’s statement: conditioning in baseball is not monolithic; it varies by role but is always tethered to competition frequency.

Energy Systems and Sport-Specific Conditioning: Why “Cardio” Is a Misleading Label

The argument that baseball requires “zero cardio” stems partly from a misunderstanding of what cardio accomplishes. The term broadly references aerobic conditioning, but athletic performance rests on multiple energy systems. Each sport demands a unique blend.

Baseball is characterized by intermittent, high-intensity bursts—sprinting to first base, explosive throws, sudden lunges—interspersed with low-intensity or passive periods. Those bursts lean on anaerobic pathways. Yet the ability to repeat those bursts across many games, and to recover between them, relies on a robust aerobic base. That base improves recovery rates, supports thermoregulation, and preserves muscular efficiency over time.

Football contests, especially at the NFL level, emphasize explosive power, speed and contact tolerance. Players prepare for maximal efforts interspersed with rest periods that typically span several days. Strength and anaerobic capacity dominate conditioning priorities, along with joint robustness to absorb contact forces.

Framing the question in energy-system terms clarifies why dismissing aerobic conditioning for baseball is inaccurate. The conditioning baseball players perform may not resemble long-distance running, but it often includes distance-based work in spring training, tempo runs, and active recovery to support repeatability. Training that emphasizes only short sprints without an aerobic foundation would leave players vulnerable to cumulative fatigue across the season.

Managing Recovery: Strategies That Keep Players on the Field

Sustaining a daily competition schedule requires deliberate recovery strategies. MLB clubs deploy a mix of science and practice to protect players’ bodies across months of games.

• Periodization across the year: Spring Training is the primary period for building capacity; in-season work focuses on maintenance. Strength and conditioning staff emphasize preserving mobility, tendon resilience and muscular balance rather than pursuing large strength gains mid-season.
• Role-specific load control: Starting pitchers follow strict throwing programs and rest schedules. Catchers and everyday position players might rotate days off or have active-recovery assignments. Bullpens are managed to prevent overload.
• Recovery modalities: Sleep, nutrition, contrast hydrotherapy, compression, massage and mobility sessions are routinely used. Teams monitor players’ subjective fatigue and objective markers—heart-rate variability, sleep metrics, soreness scores—to guide interventions.
• Micro-dosing: Rather than long, intense workouts during the season, staff “micro-dose” interventions—short, targeted sessions that maintain strength and movement patterns without adding excessive fatigue.
• Data-driven adjustments: Wearables, motion capture, and performance analytics allow tailoring programs. If an outfielder’s sprint times dip or a pitcher’s hip rotation decreases, staff can intervene early.

These strategies emphasize longevity. Baseball teams measure success not only by on-the-day performance but also by availability over a season. The objective is to minimize attrition so players can deliver more often.

Injury Profiles: Overuse vs. Acute Trauma

An important divergence between football and baseball appears in common injury mechanisms. Football’s high-contact nature produces fewer repetitive overuse injuries but more acute trauma: ACL tears, concussions, fractures, shoulder dislocations. Baseball’s injury profile skews toward overuse and soft-tissue issues: rotator cuff strains, ulnar collateral ligament (UCL) problems, hamstring pulls, and knee/hip tendonitis from repetitive motion.

Training must therefore be preventative as well as preparatory. Baseball conditioning programs incorporate movement quality work, eccentric strengthening, and load management to mitigate repeated strain on throwing and hitting mechanics. Pitchers, particularly, face unique stresses due to the asymmetrical demands of throwing. Programs focus on scapular control, rotator cuff integrity, and optimizing kinetic chain function to reduce risk.

These distinct injury patterns reflect divergent training emphases. Football players prioritize impact tolerance, force absorption and maximal power. Baseball players emphasize repetitive-motion durability and neuromuscular control to maintain precise, repeatable movements over thousands of repetitions.

Sport-Specific Examples That Clarify Differences

Concrete examples help translate theory into practice.

• Nolan Ryan: Frequently cited for conditioning habits that supported a long, high-velocity career. His routine, including pole runs, illustrates endurance training for repeatedly delivering power across extended outings.
• Catching legends like Yadier Molina and Ivan Rodriguez: Catchers who sustained careers through their late 30s and early 40s typically combined intense workload management with disciplined recovery and adaptive throwing strategies. Their longevity underscores the value of careful in-season maintenance.
• Football’s work cycle: An NFL linebacker or running back trains weekly for explosive collisions and repeated sprints in short bursts. Their conditioning focuses on strength, power, and reactive ability, with practice loads geared toward mastery of contact scenarios rather than daily game endurance.
• Position-specific baseball conditioning: Outfielders practice sprint mechanics and route efficiency; infielders emphasize short-burst speed and lateral agility. These tailored drills preserve specificity while limiting unnecessary fatigue.

These examples demonstrate that conditioning design tracks role demands. Misunderstanding that design leads to over-simplified statements like “no cardio needed,” which fail to account for subtleties in exercise selection and workload distribution.

When a Statement on Training Becomes a Public Talking Point

The Kelce brothers host a popular podcast and their comments carry weight with a broad audience. That reach can shape fan perceptions and potentially influence young athletes. Public comments that construe a sport’s training as trivial do a disservice to athletes who build finely tuned bodies to meet unique demands.

Lucroy’s response served two functions: it corrected an oversimplification and provided a first-person counterpoint that illustrated nuance. The exchange also reveals how athletes from one sport may not fully appreciate the micro-decisions embedded in another sport’s training culture. Cross-sport commentary can be illuminating, but it carries the responsibility to avoid sweeping generalizations.

For fans and early-career athletes, the key lesson is to seek nuance. Sport-specific conditioning exists for reasons grounded in competition structure, movement patterns, and injury risk. Coaches and strength staff tailor programs to those realities. Simplified pronouncements from prominent figures can obscure that sophistication.

Practical Takeaways for Coaches, Players and Fans

Several practical conclusions emerge from this debate:

• Match conditioning to competition rhythm. When players compete daily, prioritize sustainable, repeatable capacities and recovery strategies. When competition is weekly and contact-heavy, emphasize maximal power and impact tolerance.
• Define “cardio” precisely. Aerobic conditioning supports recovery and repeated efforts, even in sports dominated by short bursts. Use targeted modalities: tempo runs in spring training, low-level aerobic days, or short circuits that maintain capacity without inducing cumulative fatigue.
• Role-specific programming matters. Starters, relievers, catchers and position players have different metabolic and mechanical needs. Tailor volume, intensity and recovery accordingly.
• Use data, but trust experience. Modern wearables and analytics refine decisions, but experienced trainers and veteran players provide context that numbers can’t capture alone.
• Communicate clearly. When athletes from one sport discuss another, nuance prevents misinterpretation. Educating fans about specifics—why a catcher’s “squats” are actually functional repetitions across innings, or how a pitcher’s “pole runs” supported durability—adds depth to the public conversation.

These takeaways inform not only professional training but also youth and amateur development. Young athletes often emulate elite players or media personalities; coaches should clarify why certain methods suit certain sports.

The Science of Repeatability: Why Baseball’s “Marathon” Metaphor Fits

Lucroy described baseball as “a marathon, not a sprint.” That metaphor captures the core training imperative: sustain performance under repeated exposure. Science supports the idea that repeated high-intensity actions across days require an aerobic foundation for recovery and a muscular endurance base to resist fatigue-induced breakdowns in technique.

Athletes with stronger aerobic systems clear lactate more efficiently and recover heart rate and breathing thresholds faster between efforts. For baseball players, this translates into being able to maintain throwing velocity later in outings, keep sprint speed consistent across a game, and reduce neuromuscular drift that compromises hitting and defensive technique.

Over months, those small advantages compound. A small decline in first-step quickness or throw accuracy on day 50 can cascade into missed plays and increased injury risk by day 100. Conditioning designed for longevity mitigates that drift. It does not necessarily look like marathon training; rather, it is a mosaic of targeted runs, sprint repeats, mobility work, strength maintenance and strategic rest.

Reconciling the Two Perspectives: Respecting Differences Without Diminishing Either Sport

The Kelce brothers’ comments and Lucroy’s rebuttal need not be cast as a binary—football superiority versus baseball slowness. Both sports demand elite fitness, but they demand different kinds. Football requires players to withstand violent collisions and to produce maximal force repeatedly, with several days to recover between games. Baseball demands repeated technical excellence under chronic volume and variable travel and sleep conditions.

Treating these differences as complementary helps the public appreciate the skill and discipline each sport requires. Athletes who cross-train—quarterbacks who take batting practice, or outfielders who run short sprint drills—benefit from broader athletic qualities. But coaches design professional programs to optimize for the demands of day-to-day competition. That specificity explains why what looks like “no cardio” on a podcast is actually a nuanced, deliberate approach to in-season conditioning.

How Youth and Amateur Players Should Read This Debate

Young athletes and their coaches often look to professionals for cues. Two practical lessons apply:

• Emphasize sport-specific progression. Young baseball players benefit from developing both short-burst power and a foundation of aerobic capacity, especially if they hope to play many innings or seasons.
• Prioritize recovery and movement quality. Teaching proper mobility, eccentric strength and load-management habits early prevents overuse injuries during growth spurts.
• Avoid mimicry without context. Running poles or doing 200 squats per game is not inherently advisable for a youth player without age-appropriate progression, supervision and recovery strategies.

In short, youth programs should build both robustness and skill, tailoring conditioning to age, position and competitive load.

What This Means for Cross-Sport Conversations Going Forward

Public dialogues between athletes from different sports can spark curiosity and constructive comparison. When they do, specificity and humility matter. Podcasters and commentators should clarify when they speak from personal experience and when they generalize. Former players and current pros who respond—like Lucroy—can add valuable context by sharing practical details.

Media consumers should also interpret such exchanges critically. One-off anecdotes rarely capture the full architecture of professional training. Understanding the role of season structure, position demands and injury prevention practices helps audiences separate headline sound bites from substance.

FAQ

Q: Did Jonathan Lucroy say baseball players do no conditioning during the season? A: No. Lucroy argued that position players reduce intense conditioning during the regular season because they play almost every day. He emphasized that the games themselves provide a large portion of the workload, and that conditioning strategies shift from building capacity in spring training to maintenance during the season.

Q: What did the Kelce brothers actually say? A: Jason Kelce stated that “There’s zero cardio necessary to be a good baseball player,” and Travis Kelce reinforced the point with an anecdote about running from foul pole to foul pole in high school. Their comments suggested that the typical cardio methods used in other sports are less relevant to baseball.

Q: Why does Lucroy mention “200 squats” per game? A: Lucroy used the number to illustrate the repetitive, positional demands catchers face—squatting, standing, and moving repeatedly during a game and warmups. He extrapolated these functional repetitions across many games to demonstrate the cumulative physical load catchers manage over a season.

Q: What are “pole runs” and why do pitchers do them? A: “Pole runs” generally refer to running long distances across the field—historically from foul pole to foul pole—as a conditioning method. Pitchers used such runs to build endurance for longer outings. Modern conditioning often replaces these with more role-specific work like long toss, structured bullpen sessions, and monitored throwing progressions.

Q: Is baseball “less athletic” than football because of these differences? A: No. Athletic demands are different, not lesser. Baseball requires fine motor control, rapid reaction times, and the ability to perform under chronic volume with short recovery windows. Football requires maximal power output and contact resilience with longer recovery between high-intensity events. Both require elite athleticism tailored to their sport.

Q: Should baseball players run long-distance cardio? A: Many baseball programs include aerobic work in spring training and controlled cardio sessions during the season to maintain recovery capacity. However, the volume and intensity are calibrated to avoid adding fatigue that could compromise performance. Cardio in baseball is often targeted and role-specific rather than a blanket prescription.

Q: For young athletes wanting to play multiple sports, what should they focus on? A: Develop a broad athletic base: mobility, movement quality, basic strength, and both anaerobic and aerobic conditioning. Prioritize skill development and age-appropriate workload progressions. Avoid specialization too early, and seek coaching that accounts for growth, recovery, and long-term athlete development.

Q: How do teams monitor player fatigue and recovery? A: Clubs use subjective measures (self-reported soreness, sleep quality) and objective metrics (heart-rate variability, GPS tracking, workload volume) to adjust training and recovery. Daily check-ins with athletic trainers and strength coaches allow individualized modifications.

Q: Are current conditioning practices changing because of technology? A: Yes. Wearables, motion analysis, and refined sports science have led to more precise workload management and individualized programming. Technology helps staff monitor trends and intervene before small deficits become injuries or performance drops.

Q: What’s the takeaway from the Kelce-Lucroy exchange? A: The essential point is that conditioning must be sport- and role-specific. Lucroy’s rebuttal reminds listeners that the visible absence of marathon-style cardio in baseball does not imply the absence of conditioning. It reflects an intentional approach to managing repeated physical demands across an extended season.

Q: If a fan wants to better understand what athletes do in-season, where should they look? A: Seek primary accounts from athletes, team training staff interviews, and credible sports-science reporting. Practical descriptions of routines (e.g., spring training regimens, in-season load management, and role-specific protocols) provide clearer insight than high-level generalizations.

Q: Does this debate have implications beyond baseball and football? A: Yes. It illustrates a larger point about sport specificity: successful training programs match the energy systems, movement patterns and scheduling realities of competition. Applying methods from one sport to another without adaptation often yields limited results.

Lucroy’s response to the Kelces’ podcast cut through a popular simplification and underscored a technical reality: conditioning is not one-size-fits-all. Baseball’s daily grind demands a distinct approach—one that builds endurance of a specific kind, manages cumulative load, and protects technical proficiency across hundreds of competitive moments. Understanding that nuance clarifies why a claim as simple as “no cardio” misses the substantive work players do to stay effective from Opening Day to the postseason.
