ForceDecks App Protocol

Starting Position Starting position varies significantly significantly depending on what type of test is being performed.  
For example: 
  • Isometric Posterior Chain: start lying on back with knees bent 90 degrees, heels resting on the plates on top of a box, and a loaded barbell resting across hips
  • Isometric Mid-Thigh Pull (IMTP): start in standing position with knees slightly bent, gripping IMTP bar with slight pre-tension
  • Athletic Shoulder (ASH) Test: start lying face down on ground, with hand placed on centre of plate.
  • Isometric Squat Hold: start in standing position with bar across the individual’s shoulders and squat to quarter depth, chest up and facing forward.
