See thats a problem right there, although push ups are great, they are for cutting up your body. So this is a possible reason why your getting more cut and toned rather than getting more bulk.
Incorrect once again.
The only thing that matters is your calory balance. If you've ate more than you've burned you will gain weight. If you eat less than you burn you will loose weight.
Incorrect once again ? Seriously you need to stop trying and proving me wrong all the time, like I said before find something I have said that has been wrong, if you can't than close your mouth.
There are different exercises for bulking and for cutting up. Just like there is different exercises for anerobic exercise, as there is for aerobic exercise.
L_I_S said before he does pushups for 2 minutes, this is an endurance exercise, and will not help in bulking. He is not lifting heavy and he is doing many reps. For eg. it is like doing 10kg benchpress for 2 minutes, probably even lighter.
You should check out the rest of the post where you got my quote from, because im sure i said you have to EAT, and im sure ive said it before in other posts that you have to eat if you want to bulk.
