Standing long jump: the main strength-thigh and calf muscles; Auxiliary strength-all other muscles (waist and abdomen muscles are more important); Negative effects-None
Simply put, the enhancement of strength will inevitably lead to the increase of weight. Both of these movements are aimed at overcoming gravity, so it is necessary to improve the strength of key working parts and reduce or try not to improve the strength of "useless" parts. Because different key parts are needed, there is a mutually restrictive relationship between them. Coupled with other factors, if you want to improve the performance of pull-ups and standing long jumps at the same time, my suggestion is:
1 If you are fat, you should have a foundation for leg strength. The primary goal is to reduce fat with aerobic body, and to train muscle strength of upper limbs and waist and abdomen.
If you are thin, focus on the strength training of upper limbs and waist and abdomen muscles, and cooperate with the muscle group training of lower limbs.
If you have a moderate body shape, you can use aerobic exercise to reduce fat in addition to the same exercise as thin people.
The above is the foundation. If you can improve your sports skills and physical coordination, you can greatly improve your grades.
Pull-ups: If the examiner has no strict requirements, you can provide a little upward motivation by swinging your waist and abdomen (kicking is useless), which depends on your own experience. If it is an elastic lever, this effect will be very obvious.
Standing long jump: when jumping into the air, try to stretch your body into a "C" shape (jumping from right to left). When landing, quickly tuck in your abdomen and stretch your body forward into an inverted "C" shape. This also needs more practice.
You didn't see the reward score was zero until you answered it. You are so stingy! This is all my own personal experience. Thanks!
