Extended data:
Anyone who ties sandbags to his feet should practice his feet. People who practice martial arts since childhood are usually not very tall, because they may tie some training tools that they didn't have since childhood, or lift heavy objects. To give a few examples: Jackie Chan, Jet Li and Chiu Man-Cheuk, all of whom have kung fu backgrounds, are all martial arts practitioners.
In addition, athletes will also tie sandbags to their feet, and they will tie sandbags when practicing at ordinary times to make their feet adapt to that heavy feeling. After getting used to it, when the sandbag is removed ... the runner will feel like flying; When a Taekwondo player kicks an opponent, the opponent will feel that he has been swung by an iron bar. There are many uses such as "such as". If you want to strengthen a certain part, do strengthening or gravity training for that part.
Of course, it is best not to do this during the development period. After all, it's like gravity is heavier than others. After the development period, it is ok to tie some in moderation, but don't tie too much to avoid hurting your feet. Basically, there will be no side effects, but if you tie it for too long and don't take it off, your muscles will remain inelastic and stiff, so you can't run fast in the sprint. ?
So remember not to tie it for too long when practicing. It's best not to tie it to your feet when something goes wrong, and then tie it when necessary. Then take it off after practice, which is better.
