1. Progressive overload: gradually increase your training load. The load is related to the following factors: ① training weight; 2 times; ③ Number of groups; ④ The group is intermittent.
2. Measure the relative intensity of weight-bearing training with RM: RM of training weight is related to three factors: times, number of groups and interval between groups. The strength training group has a long interval and sufficient rest, one group has 3~6 times and the other group has 5 times.
3. capacity = weight x times x number of groups: some exquisite people will multiply the distance to work.
