Push-ups and sit-ups generally speaking, one action is four groups, and a group of 8- 12 is exhausted. According to the training intensity, the training effect to be achieved in the plan and the training effect to be achieved in the plan, the interval rest time ranges from 30 seconds to 3 minutes.

Fitness people, athletes and ordinary fitness people all adopt the method of collective exercise, because a large number of scientific experiments and events show that through collective exercise, muscles can be more stimulated and grow faster. When the number of groups is 4 and the number of times is 12, the muscle stimulation reaches the maximum and the growth is the best.

Extended data:

It is best to do 100 ~ 150 push-ups a day, divide them into working groups, and do 20 ~ 50 push-ups at a time. The total number can be adjusted according to the compressive strength of human body. The best time for sit-ups is 2 hours after meals and 2 hours before going to bed, which can promote digestion and absorption of the stomach and improve sleep.
