This is the best spot for decline push-ups, it is higher than the typical bench height and thus increases the difficulty.  Diamond decline push-ups is more challenging than the standard decline push-ups.


During the push-ups days, I usually perform the incline push-ups at the end because they are the easiest and I do it until failure to completely worn out my chest.  Incline push-ups targets the lower portion of the pectoralis major which helps improve the function of moving the arm to and from the center of the body. 



Count how many seconds can you hold in this position :)


Don't know what is this called but it is damn difficult and your ABS will thank you!  I suppose to lean my body forward as much as possible while lifting those legs.
