Apply Powerbooster 10 minutes before working out and stretch as normal. This will allow the cream to penetrate deep into the muscle and tissue, and provide the most effective relief. If you suffer from tight muscles and are prone to cramping after workouts, apply Powerbooster to the afflicted regions post-workout using circular motions moving outward. Great for use on the chest, shoulders, arms, wrists, back, waist, stomach, obliques, thighs and calves. Powerbooster restrains phosphodiesterase and activates protein kinases to separate fats and promote healthy skin. Non-slip and non-stick formula dries quickly to prevent slippage from oily skin.
