If you want to lose weight, don't pay too much attention to speed and frequency. What you need is to spend more time. For example, if you are divided into three groups in an hour, the interval between them should not exceed two minutes, or you can even be divided into four groups, with only one minute's rest. The reason why we don't pay attention to speed and frequency is because speed and frequency are made by athletes, because they need explosive power! Just like doing push-ups, if you just want to exercise, you can do several groups every day, but if it is easy for you to do several groups, you can strengthen the difficulty of push-ups, such as pushing every group!
