SYNERGISTIC MOVEMENT This is the bread and butter mass-building exercise and is referred to as the synergistic movement as a result of the fact that several primary muscle groups and secondary muscle groups work synergistically or symbiotically together to perform the lift. This is where the vast majority of muscle fibres will be stimulated and it is no secret that the big compound, multi-joint, “synergistic” movements are the best for overall muscle mass development. A prime example of such would be the bench press, which targets the entire pectoral girdle, but also utilises the input of the deltoids and triceps as secondary movers to complete the lift. THE MYOTATIC REFLEX This is where the real “wizardry” of the training method comes into play. When a muscle is extended in a deep stretch movement beyond its usual range of motion, it is purported that as a defence mechanism or almost as an emergency reaction the body can activate a far wider, and sometimes deeper, lying spectrum of muscle fibres on the upward, concentric, or “flexion” portion of the movement. An example of such would be a lying incline dumbbell curl. The positioning of this movement takes the arm’s range of motion way behind the shoulder and the hand extends way beyond the hip on the downward or eccentric portion of the lift, and as such out of the bicep’s regular “comfort zone” in terms of its usual movement. To avoid possible damage or trauma to the biceps, more muscle fibres are recruited or activated at the bottom portion of the lift, at the stretching point, during the concentric, as the weight is raised upward to the shoulder. This is great news for us as greater stimulus to overall muscle fibres results in better overall development! PEAK CONTRACTION Peak contraction is where the muscle contracts powerfully in an isometric contraction, against resistance. In the POF workouts, Steve usually advocates this as a “finishing” move, and it is suggested the above order of “flexions” be followed, however the order of such movements is not set in stone and one can play around with the order to see what works for them. Steve suggests that the contracted position under resistance, of a muscle, is the best way to finish off a muscle group having undergone the above two mentioned “flexions” and as such create the best training environment for overall muscle fibre stimulation and thus growth. A good example of a peak contraction exercise would be the leg extension machine for quads or the concentration curl for the biceps. >> ! G I B T E G www.muscleevolution.co.za 67
