1, action times.

Training the muscles of a certain part of the body usually requires practicing several groups of movements, and each group of movements contains thousands of repetitive movements. It is generally believed that muscle exercise should not exceed 15 times at most and not exceed 6 times at least. In addition, large load, few times and few groups can improve muscle strength and muscle volume, while small load, multiple times and multiple groups of exercise can reduce fat and make muscle lines clearer.

2, the weight of the instrument.

Everyone's strength is different How should a friend who has just started fitness decide the weight of the equipment that should be used in exercise? One way is to practice an action (such as doing push-ups with a barbell) if you can practice 12 (the last two or the last one) at a specific weight (such as 60 kg).

This weight is the right weight to practice this action; If you can easily do 12 or more than 8 exercises, then this weight is not suitable for beginners. Another way to choose a suitable weight is to be able to lift the weight more than 15 times without any discomfort, and this weight is the correct weight.

3. Increase the load.

Fitness bodybuilders, through a period of exercise, their muscles become stronger and more powerful, so as to continue to increase their muscles: strong or keep a good body.

All human activities need muscle contraction, which is an important guarantee to maintain the basic viability of the body. People who lose muscle function can't take care of themselves. In physical exercise, the body should have certain muscle strength, and this strength comes from exercise. Sports skill training is an important basis for improving sports technical level and sports level.
