Look at your physique. If you haven't practiced before, start with the first style. If you exercise regularly, your health will be better and the interval will be shorter. You feel that, generally speaking, after the first group is finished, you can stick to at most two, and then stop. The second group can keep the same number as the first group, and the second group will not be exhausted. It is generally recommended to increase the number of the second group, which can improve your muscle strength.
Prisoner's fitness is about the control and application of muscles and strength, not the pursuit of numbers, quality is the most important.
