Jeff Cavaliere — Physical therapist and strength coach behind the fitness channel ATHLEAN-X, and former head physical therapist and assistant strength coach for the New York Mets. Known for biomechanics-driven training advice.
The gist
Andrew Huberman and Jeff Cavaliere lay out the building blocks of an effective, sustainable exercise program. They cover how to split strength and conditioning (roughly 60/40), why the best split is the one you'll actually stick to, and how to blend cardio with resistance work. Cavaliere explains local versus systemic recovery, using muscle soreness and grip strength as readiness gauges, and details the mind-muscle connection and his 'cramp test' for muscle activation. The conversation also dives into stretching types and timing, why the upright row is risky for the shoulder, how gripping in the fingertips causes golfer's elbow, and a simple non-exclusionary 'plate method' for nutrition.
Big reveals
- Cavaliere's first rule for choosing a training split isn't effectiveness, it's adherence: 'a split not done is not effective.'
- Grip strength is a strong proxy for systemic recovery; a ~10% drop in grip output means you should skip the gym that day.
- He flags the upright row as a potentially dangerous movement that forces the shoulder into internal rotation under elevation.
- The upright row mimics the Hawkins-Kennedy shoulder impingement test position almost exactly.
- Letting a bar drift to the fingertips during pulls overloads the FDS muscle and causes medial epicondylitis (golfer's elbow).
- Cavaliere does not exclude carbs, eats sweet potatoes, rice, and pasta, and argues non-exclusionary diets are the most sustainable.
Things worth remembering
- Cavaliere keeps workouts to an hour or less and says with age, workout length causes more problems than intensity.
- His mantra: 'you can either train long or you can train hard, but you can't do both.'
- The 'cramp test': if you can flex a muscle to the point of near-cramp, you can likely stimulate it well under load.
- At the Mets, they took baseline grip-strength measurements in spring training and re-measured every 2-3 weeks to track recovery.
- Trying to make a hard fist right after waking shows reduced grip output because the nervous system isn't fully online.
- Passive stretching can briefly impair motor patterns; a golfer may need a few holes to recalibrate a stored swing engram.
- Muscles tend to 'heal shorter' during sleep, so stretching late in the day helps preserve length and leverage.
- A 'high pull' (hands higher than elbows) gives the same shoulder/trap benefits as an upright row without the internal-rotation risk.
- Cavaliere maps the body as mirror joints: hip mirrors shoulder, knee mirrors elbow, ankle mirrors wrist, foot mirrors hand.
- His 'plate method': picture a clock, set the hands to 9:20, with the largest portion fibrous (green) carbs, then protein, then starchy carbs.
