In fact, you don't have to use dumbbells to exercise, but you can also achieve the effect of exercise in other ways. A series of aerobic exercises, such as pull-ups, push-ups, sit-ups, running, etc. , can make the body get a good exercise. The key to exercise is not to have good fitness equipment, but to have an optimistic heart. The most important thing is to have perseverance and perseverance. If you don't have perseverance, then even the best fitness equipment will be furnishings.

Plastic bags hold things. What's in it? Sand? Even if the weight of your homemade dumbbell reaches, have you thought about the volume? Is it convenient to hold it? Can some actions be done? It is also possible that the action is not standardized and causes accidents, and so on. You should consider all these, and don't let fitness turn into a tragedy in the end! If you want to do it yourself, I suggest you go to some building materials markets or waste recycling centers, buy some steel pipes and iron blocks and go to other people's welding materials processing places to spend a few dollars for them to weld for you. If you want to be beautiful, you can buy a bottle of your own paint (choose your favorite color) and spray it down, so that the homemade dumbbell will be fine, not much worse than the one you bought, and it is also very cheap!

We will succeed as long as we firmly believe. Come on!
