Understanding human body movement – physiology – is the key in lifting heavy weights. Skeleton and muscles make a lever system that works together – the lever system (human body) has a rigid rod (bones), a pivot point (joints) and force applied (muscles). This biological mechanism is designed to move the particular way (biomechanics).
Keep your body form, be the machine
When you do chest press on the exercise machine you want it to be intact and move smoothly. If some of the steal parts are bent, damaged, broken you will report that to a gym instructor or a personal trainer for it to be fixed. When you do free weight exercises, there is no machine – except your own body. Correct body form is essential for the biomechanics function smoothly and at its highest capacity.
Weight training is resistance type of training. Many people think that lifting weight you just have to resist gravity so that the weight goes up and down. For example, the poor understanding – squat is an exercise where you lift bar on your shoulders up and down. If you try it in this straight forward fashion – you will only be able to lift a negligible percent of your true potential or you will end up in a hospital, or both. Squat puts pressure on the whole body engaging agonist muscles (prime movers), synergist (muscles assisting agonist), fixators (muscles that prevent movement at joints other than the ones employed to exercise) and relaxing antagonist muscles (opposing muscles that relax allowing agonist do the work). Just focusing on the obvious task – lifting weight up and down – prime movers and synergist muscles engage, while fixators do not resist the weight properly (due to not focusing on them as they don’t lift the weight directly). That results in broken body form.
Just like any broken machine, human body in poor form does not work neither smoothly nor safely. Hence, specific technique must be applied to coordinate different body parts and muscle groups to lift weight in a firm and flawless form. Learning how to keep the correct posture under resistance is what everyone should start from. Free weight training without the form is inefficient and dangerous. To a degree that applies to most weight training exercises, not only big compound movements like dead lift or squat. Performance on bench press, pull ups, bent over rows and even standing biceps curls can be improved dramatically by keeping the tight, neutral form.
