Don't use equipment to exercise casually. One may be injured at the beginning of training, and the other may be that some muscle groups are too developed and the body is uncoordinated.

There are two kinds of exercises in the gym, aerobic and anaerobic. Typical examples of the former are jogging, brisk walking, swimming and cycling. Typical examples of the latter are combined instruments, barbells, dumbbells and sit-ups.

Aerobic exercise can lose weight, but it is actually consuming subcutaneous fat. Anaerobic exercise can strengthen the body and build plasticity, which is actually to increase muscles.

If your goal is to increase muscle, you can achieve it through anaerobic exercise.

If your goal is to increase subcutaneous fat, then fitness is useless to you. What is needed is to increase nutrition and eat more foods that contain more starch and fat and are easy to absorb.

Pay attention to a lot of lean meat, chicken and fish in the diet, which is not conducive to increasing subcutaneous fat.
