If the hip and knee cannot be stiff enough, a huge overload lands on the ankle, and even a stiff ankle cannot withstand the mechanical loading — so ankle collapse at high speed may originate higher up the body.

Claim from Dr. Jean-Benoit Morin
Recommendation · Body
Lean slightly forward during the single leg squat to target the glutes and hamstrings. To focus on quad development, put the foot tighter so the knee tracks forward more. The single leg squat with a slight lean forward increases mobility.

Recommendation from Garage Strength
Recommendation · Body
Jeff Cavaliere advises against sliding the hips back and then standing up when pushing out of a forward lunge; instead, keep the knee bent and come straight up.

Recommendation · Body
Jeff Cavaliere advises that if you have ankle dorsiflexion limitations and cannot reach full depth, stop at your available depth and continue.
ATHLEAN-X™ · Stop Doing Lunges Like This! (SAVE A FRIEND)
Recommendation from Jeff Cavaliere
Recommendation · Body
Jeff Cavaliere warns that if you have ankle limitations, avoid pitching forward to appear lower, as it shifts focus to the posterior chain away from the quads.
ATHLEAN-X™ · Stop Doing Lunges Like This! (SAVE A FRIEND)
Recommendation from Jeff Cavaliere
Recommendation · Body
Jeff Cavaliere recommends leaning forward by hinging at the waist during a reverse lunge to target the glutes and hamstrings (posterior chain), calling it a 'sprinter lunge'.
ATHLEAN-X™ · Stop Doing Lunges Like This! (SAVE A FRIEND)
Recommendation from Jeff Cavaliere
Recommendation · Body
Jeff Cavaliere recommends that if you must do forward lunges, continue in a walking direction by stepping forward and through rather than compensating backwards.
ATHLEAN-X™ · Stop Doing Lunges Like This! (SAVE A FRIEND)
Recommendation from Jeff Cavaliere
Recommendation · Body
Jeff Cavaliere recommends stepping back and out to at least shoulder width or wider to provide a stable base of support for the lunge.
ATHLEAN-X™ · Stop Doing Lunges Like This! (SAVE A FRIEND)
Recommendation from Jeff Cavaliere
Recommendation · Body
Jeff Cavaliere recommends keeping an upright torso during a reverse lunge to target the quads (anterior chain).
ATHLEAN-X™ · Stop Doing Lunges Like This! (SAVE A FRIEND)
Recommendation from Jeff Cavaliere
Recommendation · Body
Jeff Cavaliere advises against stepping too close together in the lunge, as it turns the exercise into a balance test rather than a leg builder.

Recommendation from Jeff Cavaliere
Creator perspective · Body
Jeff argues that avoiding apples, grapes, and carrots because they supposedly block a six-pack is a distraction from the bigger-picture nutrition items that actually matter, and that extreme nutrition tactics are used to avoid facing changes one isn't ready to make.
ATHLEAN-X™ · I'm 51. Here's How I Still Have Visible Abs (WORKS AT ANY AGE)
Claim from Jeff (Athlean-X)
Creator perspective · Body
The host explains that the pull-up is a troublesome exercise for people with a bum shoulder, though less obviously so than the bench press. Hanging creates traction stress that pulls the arm up, and without an intact labrum you lose stability of the ball in the socket, like a suction cup that no longer works.
ATHLEAN-X™ · 7 Exercises That Are Making Your Shoulder WORSE
Claim from Jeff Cavaliere (Athlean-X)
Creator perspective · Body
The host explains that the bench press is a classic chest builder but must be done right to avoid wrecking the shoulders. Structures susceptible to aggravation include the bicep tendon, the rotator cuff, and to a lesser extent the labrum. Getting the bar down requires the elbow behind the body, putting the shoulder into extension, which stretches the long head of the bicep tendon across the area; under load this can become problematic.

Report · Body
When running fast, good athletes' ground contact times are around 100, 120, or 150 milliseconds — an extremely short window to express force that people very often overlook.

Report · Body
In a training intervention specifically targeting the intrinsic foot muscles, highly trained people showed real improvements, including improved change of direction performance and some high-speed metrics.

Report · Body
Today there are papers, including Chris Bramah's score — the only study so far linking sprint kinematics with hamstring risk in high-level English soccer (EPL). A higher score relates to higher hamstring injury risk. The score has 12 items, so a player could be perfect on the collapse item, have wrong numbers on other items, and still get injured; no specific link has been established between each individual item (e.g., trunk angle, pelvic tilt) and injury risk. When asked, Bramah said the collapse item (a huge collapse or not at mid-stance) was very often observed in future hamstring-injured players.

Recommendation · Body
Dr. Morin recommends grading qualitative video assessment as good, average, or bad — with no numbers — and explains that a series of these ratings reveals what an athlete needs to work on.

Recommendation from Dr. Jean-Benoit Morin
Recommendation · Body
Dr. Morin recommends doing your own research in your own context, because maybe no published study corresponds to your situation. He argues a small correlation coefficient difference cannot be extrapolated to all contexts and all players, and notes he was a co-author — but never lead author — on studies comparing exercises and their correlation with sprinting, because he doesn't think it's a good approach.
Garage Strength · Why Most Athletes Train Speed Wrong w/ Sprint Scientist Dr. Jean-Benoit Morin
Recommendation from Dr. Jean-Benoit Morin
Recommendation · Body
Dr. Morin recommends skepticism toward commercial movement-measurement solutions' validity and reliability claims: no company selling such solutions has ever said its product is not reliable, so marketing claims are biased, and lab-comparison data is not yet ideal. He remains a bit skeptical for now.
Garage Strength · Why Most Athletes Train Speed Wrong w/ Sprint Scientist Dr. Jean-Benoit Morin
Recommendation from Dr. Jean-Benoit Morin
Creator perspective · Body
Dr. Morin explains that doing too much top-speed sprinting exposes players (e.g., soccer players) to overexposure and possible injury risk, so the goal with max velocity sprinting exposure is to avoid both underexposing and overexposing athletes.

Perform rounds of kettlebell swings, suitcase marches and cleans continuously for 5 minutes. When you need a break, hold the bell in a goblet hold or clean position instead of setting it down, and the moment it hits the floor, the challenge is over.
Fitness · Advanced
Run a five-minute kettlebell grip challenge with no straps and no chalk, repeating a round of swings, marches and cleans for as long as you can hold on. If you drop the bell, the challenge is over.

Get into a cold shower for one to five minutes before cognitive or physical work when you want to improve concentration and focus.
Sleep · Advanced
Go to bed and wake up at the same time every day, even on weekends, and spend the time before bed doing something relaxing instead of screen time.
