do pushups help you gain muscle mass in ure pecs,arms,shoulders,etc? say u do 250 pushups a night. would i gain increases in my pecs and arms or is it just an endurance thing?

thx in advance for any replies

they will help build mass, but not as much as you could with heavier weights.

I already asked that same question someone before; you will see some pretty big results when you start doing them but later you will see very small changes, it’s better to lift heavier weights.
