The lack of inertia and negative resistance enables safe, unspotted, high force, high speed, high intensity partial reps.

Protocol Example: Bench Press Partial Reps - After the completion of the standard 12 rep set, to exhaustion at full range of motion, reduce exercise movement to the top 1/4 of extended arms stroke position and have your trainer/partner increase resistance 20- 50%. Do as many Partial Reps as possible to exhaustion, ending in "micro-reps", very short 1 to 3 inch reps, fast (1 second maximum work and ¼ return), at full arm extension. Again, working the muscle to exhaustion with high speed, high resistance exertion in its strongest range of motion, produces incredible POWER increases fast.
