Hmm, strong dude for sure but his form leaves something to be desired.
Wonder what he could do on bench if he didn't wear the shirt and performed full lock-out reps?
I recently ground out a set of 7 with 185lbs on bench. Each rep was locked out though.
No video of course.
I spent four years studying anatomy and physiology.
I've had human anatomy, physiology, exercise physiology, biomechanics I, biomechanics II, molecular aspects of muscle physiology, Human dissection, and practical labs for each of those classes.
I once wrote an 11 page paper describing the biomechanics of a free-bar squat, including a special emphasis on how femur length in relation to tibia length can alter forces at the patella.
I had to solve a formula for the change in pressure at each vertebrae as a given weight moved at set intervals away from a fulcrum point of the anterior aspect of the vertebral body.
I had to explain how size and shape of the superior articulating facet and size and shape of the inferior articulating facet can create a predisposition to ruptured disks.
There's very little about 'form' that I wasn't forced to learn. You could write books about it (and people have), but in the end, there are too many processes and fulcrum points in the human body to create a generalized "good form" on an exercise.
In the squat, you would have to consider femur length in relation to tibia length, also including food length, ankle size, thickness of the meniscus in the knee, hip size and shape, as well as the specific ratio of kyphosis or lordosis of each vertebrae in the spine (also taking into consideration the size of each vertebrae).
This was the longest, most pointless post ever written.
