Do you want to buy dumbbells for fitness?

No need, the gym is well equipped, and remember not to go every day after each workout, and go every other day. Every time you do anaerobic exercise, you should destroy your muscle tissue as much as possible, and then use enough time and nutrition to repair the damaged muscle tissue and let it grow. To put it bluntly, muscles grow out at rest after anaerobic exercise. Be sure to combine aerobic exercise to lose excess fat. If you only do anaerobic exercise, the fat layer will not decrease and the muscle layer will increase, which will make you fatter and the muscles will not be seen at all.
