What Jeff Cavaliere’s Time With José Reyes Can Teach About Speed, Durability and Athletic Training
UPLIFT IRON CLUBCavaliere, Reyes and the Real Meaning of Athletic Training
Jeff Cavaliere’s years with the New York Mets are often reduced to a credential in an ATHLEAN-X bio, but José Reyes makes that period more interesting than a line on a résumé. Cavaliere served as the Mets’ head physical therapist and assistant strength coach during the 2006–2008 National League East championship seasons, and his own biography lists Reyes among the All-Stars he worked with. That placed a physical therapist and strength coach beside one of baseball’s most explosive runners at the point when speed was central to the Mets’ identity.
Reyes was not simply “fast for a baseball player.” He stole 64 bases in 2006, a franchise-record 78 in 2007 and 56 in 2008. His game demanded repeated acceleration from awkward starting positions, hard turns, slides, defensive reactions and enough availability to do it over a six-month season. That is a better model for athletic training than chasing a single flashy drill.
The useful lesson is that speed is a system. Strength matters, sprint exposure matters, technique matters, and so does arriving healthy enough to express those qualities. Cavaliere’s later content often blends those same ideas: build force, move explosively, respect joint mechanics and treat durability as part of performance rather than as an afterthought.
Acceleration Is a Skill, Not Just a Genetic Gift
Baseball speed is dominated by short bursts. A runner leaving the batter’s box or stealing second does not get a long runway to build velocity; the first few steps decide whether a routine ground ball becomes an infield hit or whether a catcher’s throw arrives first. Reyes built a career on winning those tiny races.
That is why acceleration deserves its own training emphasis. A 2024 systematic review found resisted sprint training produced a significant improvement in 10-meter acceleration compared with normal sprinting, while differences at longer distances and maximum velocity were less clear. The point is not that everyone needs a sled. It is that short, high-quality acceleration work can be trained deliberately rather than hoping ordinary conditioning makes you faster.
For a recreational athlete, a sensible session might use four to eight sprints of 10–20 meters with generous recovery, stopping when times or mechanics clearly deteriorate. Hills or light sleds can provide resistance, but the load should not turn a sprint into a slow grind. The goal is still violent, coordinated acceleration: push the ground away, project forward and let the stride open naturally as speed rises.
Strength Should Feed Speed—not Compete With It
Speed without strength is fragile. The lower body has to create large forces quickly, while the trunk and upper body transmit and organize those forces. That does not mean a baseball player should train like a powerlifter. It means foundational strength gives sprinting, throwing and changing direction more force to work with.
Cavaliere’s modern demonstrations often pair traditional strength work with jumps, carries, unilateral exercises and athletic movement. Heavy squats, split squats, hinges and calf work can build force capacity; jumps and sprints teach the athlete to express force rapidly. Pulling, pressing and trunk training keep the rest of the body robust enough for sport.
The important distinction is transfer. A bigger deadlift can be useful, but only until the pursuit of the deadlift starts stealing recovery from sprinting, skill work or games. Research comparing heavy and fast strength approaches finds no universal winner for sprint development. Athletes need enough strength, enough velocity exposure and a program that matches their individual deficits. Reyes did not need the strongest legs in the league. He needed legs that could repeatedly turn force into baseball speed.
Durability Is Part of Speed
Reyes also illustrates the uncomfortable half of athleticism: explosive athletes can be difficult to keep healthy. His career included significant leg injuries, including hamstring problems, even though he also produced long stretches of elite availability. That tension is exactly why durability cannot be separated from speed programming.
High-speed running is a potent stimulus, but it is also demanding. Hamstrings must absorb and redirect large forces at speed. Research on sprinters has linked faster thigh motion and greater eccentric hamstring strength with higher top speed. That reinforces the logic of training the tissues that have to tolerate sprinting rather than avoiding speed altogether.
Recovery placement matters too. A 2024 meta-analysis found muscle-damaging resistance and plyometric sessions could impair sprint and change-of-direction performance for up to 72 hours. If speed is a priority, burying sprints after a brutal leg session is backwards. Put the highest-quality speed work when the athlete is fresh, then organize strength and volume so the next important field session is not performed on dead legs.
The Physical-Therapy Lens: Manage Risk Without Training Scared
Cavaliere’s Mets background matters because physical therapy changes how a coach looks at performance. The job is not merely to make an athlete stronger on paper. It is to understand what movements the sport repeatedly asks for, where the athlete has limitations and how training stress fits around competition.
A useful warm-up should prepare the exact qualities about to be trained: temperature, joint motion, progressive accelerations and rehearsals of the movement pattern. Corrective work should solve a real problem without exhausting the athlete before the main work begins.
For a fast player, durability also means maintaining exposure. If sprinting disappears for weeks, the eventual return to full-speed running can become a much larger jump in demand. A better plan builds high-speed work progressively and keeps doses small enough that quality stays high. Athletic training is about improving capacity while managing the demands that come with performing.
Another useful principle is sequencing. A speed session should move from general preparation to increasingly specific work: easy movement, dynamic range, a few drills, then progressive accelerations before the fastest efforts. The warm-up is successful when the athlete feels sharper at the end, not merely tired. The same logic applies in the weight room. Preparation should improve the positions and force production needed for the main lifts without consuming the energy those lifts require.
This is where the therapist-coach overlap is valuable. The athlete is not a collection of isolated muscles; training decisions have to account for the next practice, the next game and the accumulated workload of the week. A technically perfect accessory exercise has little value if it reduces the quality of the sport work that actually matters.
A Practical Speed-and-Strength Template for Normal Lifters
The most transferable lesson from the Cavaliere-Reyes overlap is not a secret Mets drill. It is the hierarchy of priorities. First, practice the athletic quality you care about while fresh. Second, build enough strength to support it. Third, use accessories and mobility work to solve real limitations. Fourth, protect recovery so the athlete can repeat high-quality work.
For a gym lifter who wants to feel more athletic, that could mean two short speed exposures per week. After a progressive warm-up, perform five 15-meter accelerations with full recovery. On another day, use four to six low-volume jumps before strength work. Keep two or three weekly strength sessions built around a squat or split squat, hinge, push, pull and trunk exercise. Progress the lifting, but do not let soreness become the scorecard.
Then watch the boring signals: sprint quality, joint irritation, sleep, enthusiasm and whether performance is actually improving. Reyes’ speed was spectacular because it showed up in games, not because a drill looked impressive on camera. Cavaliere’s most useful legacy from professional baseball is the same idea. Training should make the athlete more capable on the field and ready to keep proving it.
Keep the sprint doses genuinely fast. If five accelerations are planned, each should look like speed practice, not conditioning disguised as speed. Rest two or three minutes when needed. Stop early if times slow noticeably or mechanics unravel. Conditioning can be trained elsewhere; the nervous system learns speed best when fatigue is low enough to preserve intent.
A simple weekly layout could place accelerations before lower-body strength on Monday, upper-body strength on Wednesday, and jumps plus a second short acceleration exposure before full-body work on Friday. That arrangement is not sacred, but it demonstrates the principle: put the most velocity-sensitive work first, then strength, then lower-priority accessories. Adjust volume around sport practices and games rather than forcing every quality into every session.
