The main muscles used are biceps, rear delts, and upper back. With the dip you ad triceps and chest. Of course all the other muscles that involve griping the bar or rings, and the kipping motion using core muscles.
The primary muscles involved in a pull-up exercise are the latissimus dorsi (back muscles), biceps, and forearms.
Exercise is the natural way to "grow" muscles, though there is no growing actually involved. If you want larger, better defined muscles, you work out.
Dumbbell curls are considered a pull exercise because they primarily work the muscles involved in pulling movements, such as the biceps.
No. The Kegel exercises are designed for toning and tightening the PC muscles, the supporting muscles of the pelvic floor, aka the pubococcygeus muscles. The exercises involve the contracting and releasing of these pelvic floor muscles in a controlled way. The large muscle groups that are exercised with jumping and trampolining do not exercise the PC muscles. So, unless you at the same time clench the muscles that you clamp to "hold it in" (like when you have to urinate) while you jump on the trampoline, you will not be doing any exercise of the muscles involved in Kegel exercises. There are no muscles called the Kegel muscles. See the related questions for more details.
Muscles get their strength from exercise.
With exercise bands, you can work out tons of muscles. Muscles that you can work out are arm muscles, leg muscles and back muscles. With leg muscles, you can work out the thighs, and calves muscles.
The primary muscles used in the snatch exercise are the quadriceps, hamstrings, glutes, shoulders, and back muscles.
The muscles primarily used in the farmer's carry exercise are the forearms, shoulders, and core muscles.
During a dumbbell raise exercise, the muscles primarily worked are the deltoid muscles in the shoulders.
During a lateral raise exercise, the muscles primarily worked are the deltoid muscles in the shoulders.
Lactic acid is produced by our muscles during exercise.
The skull crusher exercise targets the triceps muscles in the arms.
