Ok I did a little experiment. at full up right pushup position I am I think 66% of my weight on my hands. Now with that said 66% of my weight is about 100lbs. So I dont understand why I can do way more pushups at 100lbs than bench pressing 100lbs. Dont get me wrong I can I just cant do it as easily as a pushup. Any idea? I thought it was working the exact same muscles.
