yes but then his answer is wrong.

i can do consecutively 40-60 push ups.

Well if it took you 75 seconds to do 30, I doubt you could do 40-60. :p

so you think i cant do push ups for lets say 3 minutes and 30 secons..
time has nothing to do with how many push ups you can do. If you do push ups too fast its easier, if you do them slower its harder to do..
If you do fast then you are just "bouncing" up and down.

I doubt you could remain in the inactive pushup position for 3.5 minutes. lol.

I only can do like.. 31 push-ups. My biceps aren't that strong

Pushups are all triceps and chest. No biceps involved.
