Push-ups mainly rely on the muscle strength of upper limbs, chest, back and abdomen.
The arm flexion and extension of parallel bars mainly rely on pectoral muscle, triceps brachii and deltoid muscle (toe), and latissimus dorsi and trapezius muscle also play a role.
Relatively speaking, compared with the other two kinds of sports, the pull-ups require higher upper limb strength and latissimus dorsi strength. In the whole pull-up process, the comprehensive strength of each part is greater than the weight of the body to complete, and none of them can be done, which is why the strength is not enough to support the weight of the body.
Practice method:
For people with insufficient strength or heavy weight, you can use elastic belt as an aid or ask someone for help. At the same time, they can do straight arm hanging, arm bending hanging, low bar oblique pull-ups, hanging swing, low bar supine pull-ups, all kinds of push-ups, arm bending pull-ups, sit-ups and so on. You can also exercise latissimus dorsi with pull-down equipment.
