7-minute exercise can be divided into local exercise and comprehensive exercise.
Local exercise has a good local muscle exercise effect in the early stage, and comprehensive exercise has a good stretching and initial physical improvement effect. However, the limitations of the two are very great, and it is easy to reach the muscle bottleneck and enter the adaptation stage. At this time, they can only achieve the effect of warm-up exercise.
Fitness requires high-impedance exercise, and physical fitness is exercised through aerobic endurance exercise. Seven minutes of exercise can only improve physical fitness initially, which is basically equivalent to advanced warm-up. It needs long-term persistence to see the effect.
