Limiting Range of Motion Through Pin placements
Throughout Block IX, we will be limiting ROM (range of motion) with strategic pin placements while continuing our PAP (post-activation potentiation) through full range accessory movements.
To decrease ROM during squats, safety pins should be set to where the start position is a half-squat. For bench presses, the safety pins should be set approximately 3-5 inches above the chest. Starting the movement with a concentric action (raising the bar) while being able to reset and not endure the isometric action of each repetition allows individuals to continue truly training RFD (Rate of Force Development or Power) within their squat and bench press. This also means you are not utilizing the stored energy of the eccentric action (lowering of the bar).
This decrease in ROM will aid in relieving already stressed joints which is especially helpful as most individuals reach the peak of their summer season activities and sports. With that being said, full ROM in the accessory movements is necessary to continue increasing elasticity and strength in the working muscles while also increasing rigidity and strength in the tendons/ligaments involved. Which leads to our PAP (post-activation potentiation). We will continue with our PAP progression within our deadlift variation. We will make increases in weight over the course of these four weeks followed immediately by a lower body plyometric movement(speed & force). This PAP effect, with a higher intensity in the deadlift, leads to an increase in performance in the explosive bodyweight movement that follows.
