Are pushups isometric exercise?

Question

Are pushups isometric exercise?

Answer 1

No because there is both a concentric (up) and eccentric (lowering) portion of the exercise. Isometric has only a concentric portion. It is my opinion that the eccentric motion causes as much or more of the muscle growth so eliminating it is shooting yourself in the foot. Perhaps a true exercise physiologist can step in.

Answer 2

Agreed.

An example of a Isometric exercise is a Plank

Answer 3

nope..they contain both eccentric and concentric muscular contractions.  isometrics are when muscles are activated but they are neither lengthened or shortened such as when flexing a muscle or static contractions
