A group represents an action that takes different time to complete, such as doing push-ups You do 50 at a time, then rest 1 minute and do 50 again. This is called two groups. So repeat this many times, how many groups did you do?

So the training you are talking about is: do five groups of push-ups and then do sit-ups every day, which is also five groups, so that you can develop pectoralis major and abdominal muscles in one day. If you want to train other muscle groups, you can add different movements. Remember that the rest between groups should not exceed 65,438+0 minutes, which can stimulate the effective growth of muscles. It's not that you do 50 push-ups and then play for two or three hours before doing them. It just didn't work as expected.
