This guy is seriously a static beast.

Amazing show of strength. It's like the one arm pull up, so few people can actually pull it off.

Wow, very nice work out.

Don't think i'll be ready for this for a very long time yet.

I'm curious, which areas of the pectorals are worked on those push-ups and how much? I would be very interested to know specially on the push-ups shown on the training video.. such wide variety! Any expert on this?

hmmm i am ans yr query base on my limited knowledge from human anatomy....the pectoralis major is the main muscle for pushup....secondary will be yr triceps.....
for the pushup in first video....yr whole body weight is stressed on yr shoulder elbow and wrist joint....core abdominal and back muscles are used to maintain stability and posture....note the position of the elbows (shoulder width pushup) the triceps hav to work harder as more load is place on it in this position....it takes some load off the pect major
well as for the second video....abt half of yr body weight is acting on yr shoulder elbow wrist joint....in this position, the pushup is more like a shoulder raise....hence the primary muscle involve is the deltoid (anterior,medial) at shoulder joint....triceps at elbow joint....theres not much effort from pect major in this position

feel free to correct me and pardon me if theres any mistakes ty

I would also agree with you, but the upper pecs need a lot less inclination to be perfectly stimulated, so I wonder, would that position increase the stimulus or would it send most of the pressure into the shoulders?

heehee ok that posture in 2nd video does stimulate yr upper pect but the deltoids are the main mover...what u can do is to slight widen the hip angle (hands and legs further apart) which offload more weight from the deltoids to the upper packs...kindof like what u meant by less inclination shoulder raise as u go wider the load is transfered from deltoid to the upper pect and eventually the entire pect....

The wrists look like they're placed in an immensely vulnerable position for injury =\
