If you do forty opening and closing jumps every day and persist for a long time, it will have an effect, but if the time is short and the number is insufficient, there will be no obvious effect in the short term. If you want to lose weight, it is suggested to reduce the intake of high-calorie food and do aerobic exercise (jogging, dancing, skipping rope, swimming and cycling) on the basis of conditions.

Jumping jacks open and close jumps.

Jumping Jacks, translated as opening and closing jump in Chinese, is called "star jump" by kindergarten students, and opening and closing jump is the most common in warm-up exercise.

Although the method is simple, it can quickly improve the heartbeat, make the body quickly enter the state of exercise, and continue to do it, and also exercise the muscles of hands, shoulders and legs. Because it is a full-body training action, it is also a very good choice to lose weight and consume calories!

Precautions:

1, chin slightly tightened down, eyes looking straight ahead.

2. Keep your arms straight and don't bend.

Be careful not to bend your knees inward, but face straight ahead.

Suggestion:

Each exercise can set a target number of times (for example, 100 times a day, 150 times), and it can be completed in three or four groups, and each group can rest for 1-3 minutes. You can also try to open and close as much as possible in a certain period of time! For example, within 30 or 60 seconds! This is an addictive action, but we must pay attention to the standard of action!
