How many reps/set do u have to do to get these pectorals in 24 days?

1. Do you mean abs? Biceps are on the arms.

2. It really depends on where you are at currently.

3. You really shouldn't idolize a body like this (especially as it is drawn). It could harm your mental health by not reaching your goals in such a short period of time. Your goal could be to get abs within a year or so, but again it heavily depends on your current body state.
