Load up a Leg Press with a weight that would be about your 15 rep max. Use feeders as necessary to approximate this loading range. Perform sets of 5 reps as repeating clusters with 15 sec rest between them. Continue until you can’t get 5 controlled reps.
How to Progress
Progressions on “METAL” are very straightforward—Load and/or the total number of reps (as a function of the cluster sets) completed can be increased.
