When you exercise, you are very tired after doing a group of actions (such as birds). If the interval is short, you can't keep up with the second group How to practice this?
It stands to reason that it is best to do three or more exercises at a time. If one group is tired, you can finish one group and then lose weight until you can finish the first group, and so on for the third group. Of course, the best way is to practice several groups of movements in cycles. Each set of movements practices different muscle groups. After completing one set of actions, take a break and do the next set of actions.
