Correct technique of workouts is important
Remember that if doing the workout weights move along a wrong trajectory it can cause the formation of microtraumas in joints and sinews which in due course can provoke a serious injury. Therefore all movements should be done in a plane natural to a given joint.
Full amplitude of movement is also important. This means that you should stretch muscle as much as possible at the beginning of the movement and constract it at the end of movement. It is necessary in order that the muscle would develop throughout all its length - from a sinew to a sinew. Generally, movement should be smooth, without stops and delays.
