Squats is unique biomechanical structure exercise
Rod - Basic "free" is a tool bar; it is associated with all the power sports. History of this projectile begins with distant 1849. It is worth noting that the four main basic movements are performed with a barbell is: squats, bench press, deadlift, bench standing. Squats - Unique biomechanical structure exercise. The main burden falls on the muscles of the legs and back. Many believe that squats are the impact exercise for the legs.
In fact, back at work here, no less. The misconception arises because of the low trajectory. When you squat down, your body leans forward slightly. Of course, it is only straightening due to the muscles of the back. Small amplitude - this is only visual trick. In fact, weak back will not allow you to adequately perform the movement, since the beginning of the trajectory will be followed by an involuntary jerk of the pelvis, and it's pretty traumatic.
Bench - The most popular mistake beginners is too long range of motion. It is believed that the lower the lower the bar, the greater the load will get the chest. Some enthusiasts practicing lowering fingerboard repulsed with the sternum, ostensibly so that they improve their power characteristics. Speaking on the merits, the lowering of the bar too low makes you just as low down elbows. As a result, the pectoral muscles are in a rather unnatural position where they simply cannot be reduced at full strength because of the physical structure of the body. In such circumstances, perform repetition becomes hellishly difficult.
