Insulin growth factor-1 (IGF-1) is a substance which in manufactured by recombinant DNA technology. IGF-1 is the primary mediator of the growth promoting effects of human growth hormone. As such, the substance also can stimulate the growth of bone, muscle, and internal organs. Its effects on skeletal muscle are also highly hyperplasic, meaning it causes an increase in cell number.
IGF-1 is basically a polypeptide hormone that has the same some of the same molecular properties as insulin. In fact, IGF actually stands for insulin-like growth factor. IGF-1 is primarily responsible for long bone growth in children and it also affects muscle growth and repair of adults. Long R3 IGF-1 is a more potent version of IGF-1. It’s chemically altered to prevent deactivation by IGF-1 binding proteins in the bloodstream. This results in a longer half-life of 20-30 hours instead of 20 min.

Mainly exercises the muscles of the upper limbs, waist and abdomen, especially the chest muscles. It is recommended to have 30 groups, and the action should be standard. Every 4 groups or so. At the same time, you can practice three heads.
Flexing arms and extensions:
The parallel bars are flexed and extended to practice the chest muscles, triceps and deltoids (anterior bundles), and the latissimus dorsi and trapezius muscles are also practiced. This action has multiple effects, and different practices produce different effects. Two chairs can be used at home instead.
Flat dumbbell press:
The action is as shown. The weight of the dumbbell is selected according to its own situation, a group of 8-12 4 groups.
The action is shown in the figure and can be done on the door frame at home. A group of 12-14, 6 groups. At first, you may not be able to do a few, or even pull it, but as long as you persist, your own strength will be increased.
Dumbbell presses can exercise the strength of the arm. Personal feeling that the one-arm effect is good, the left and right arms are made separately
Exercise your back muscles and triceps
There are two postures on the map, the second effect is better, and the difficulty is slightly larger.
