Push-ups and pull-ups cannot be separated and will not have a good effect.
Do it in groups. The number of people in each group depends on you. If you do it in a short time, don't do it more than 20 times in each group.
Count by yourself until you feel just tired, just count a few more times, then rest and do your own thing. After seven or eight minutes, do the second group and do five groups every day, and the effect will be very good.
Then according to your own situation, continue to increase the number of each group and the number of groups. Pull-ups are the same, but the muscle positions are different.
