“I’ve done this with all my celeb clients,” says Mathews. “We work up to a heavy set of four to seven reps, then drop the weight by 30–50% and do 8 to 12 reps.” Reducing the load and cranking out more reps without rest allows you to keep training the muscles past where they would normally fail, adding more stimulus for growth. Try dropsets on dumbbell presses, curls, and machine exercises. For more on Mathews’ training, visit ronmathews.net.
