There is a simple reason. If you walk in front of a bag of 50 kg of rice for a while, you will feel much lighter after you put the rice down, and everything will become easier when you walk. This is the same reason. If you keep tying sandbags to your legs for exercise or walking, you will find that you are much lighter when you take them off ~
Leg lifts and leapfrog! These are all explosive exercises.
And long-term exercise will increase bounce! !
But pay attention! !
The human body is balanced.
When a part is strengthened, it will definitely affect the balanced development of the body.
For example, people who exercise their muscles too early are not tall.
Excessive muscle exercise will become a common problem when you are 40 years old. ..
Lead substitution. In fact, the effect is not great in a short period of 1 month to 3 months.
I just felt very clear when I took it off, and it was too heavy after a long time, so I couldn't take it off.
I will feel very light, but I will feel uncomfortable after a while, as if I have lost a piece of meat ... I will feel weak in my toes.
You can't run fast or jump high! !
So I conclude: wear sandbags or lead plates. ..
Generally, wear exercises before the body, that is, the root bonds and bouncing ligaments of the feet grow up.
Don't train too early, it will cause the decline of physical function ... people are not tall and so on.
Therefore, the second grade of junior high school to the second grade of senior high school is the best time to wear it. ..
Of course, the first 1 is ok, but because of the lack of human strength and support, it is best to add up to 1 kg.
Then generally 1~ 1.2 kg ... and it's useless to run any more squats or jumps! !
