When you reach failure in a particular exercise this
technique will come into play. At the point of failure,
begin to slightly use your other muscle groups to get a
couple of more reps. This will allow you to target more
muscle fibers than you could imagine! For example, lets say
you are doing alternating dumbbell curls and reach failure
at 10 reps. At this point you would slightly begin to use
your back and delts to lift a few more reps.
