Ensure that the body is in a state suitable for jumping, which includes: warm-up, stretching, adequate sleep and diet, and good health. Stand on a stable plane, such as a balance board or a low box, take a step forward and shift your center of gravity to your front foot.
Then, the front foot quickly squats to prepare to bounce, and the back foot takes a step forward and is placed behind the front foot. When the hind foot touches the ground, use the strength of both feet and the contraction of leg muscles to bounce quickly. At the moment of take-off, the arm naturally stretches upward, and the strength of the arm helps you complete the jump.
When landing, the center of gravity moves back to the front foot, while keeping the body balanced and bending down to absorb the impact. Repeat the above steps until the required number of jumps or jumping targets are completed.
Precautions for sports:
Muscle aches after physical exercise. It may be a sign of excessive exercise, reflecting that you are not suitable for excessive exercise.
It may also be a natural reaction after exercise, because during exercise, muscles will produce a substance called lactic acid, which will stimulate your body and make you feel sore.
As long as you keep exercising, this phenomenon will gradually disappear and your physical fitness will be improved in this cycle of physical reaction. If you stop exercising because you feel muscle soreness, it will weaken the fitness effect of physical activity until the muscle soreness disappears.
