I'm drunk for over 30 kinds. Fitness focuses on precision and sharpness. It is enough to train each part for about 5-6 times. Doing too much just increases the burden on the body in vain. Self-weight training includes many things, such as back pull-ups, chest muscles, arm and back push-ups, and double-wall bar flexion and extension. HIIT training is also a good choice if it is to reduce fat, but simple self-weight training is not enough. In order to make the muscles of the whole body develop harmoniously, it is necessary to separate the parts. There are many such equipments in the gym, such as Smith machine, which can help you get long-term development in fitness.
Fitness is about persistence. As long as you have perseverance, you will eventually reach the figure you want.
