I started doing pushups only. I reached a maximum of 30 at one time and then squeezed in around 100 pushups every day. This was going on for a few months.
Then I joined a gym. I do a full-body workout every other day and, for the sake of rest for the body, I don't do any exercise on the non-workout days.
The problem is that I am not able to do as many pushups now as I could before joining the gym.
Q1: What could be the reason?
Q2: Should I do pushups every day and squeeze in 100 in a day no matter what?
