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
