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
Isometric Squat Hold: start in standing position with bar across the individual’s shoulders and squat to quarter depth, chest up and facing forward.
