CytoSport Fast Twitch is a power workout drink designed to give users explosive strength performance and fuel fast twitch (type II) fibers. It helps to amplify nitric oxide levels for total body pumps to help you protect lean muscle mass. Fast Twitch also has an endo-thermogenic effect which maximizes fat burning after your tough workouts. Awesome muscular explosiveness and size, formerly reserved for the genetically gifted, is the goal of Fast Twitch. Fast Twitch is the first formula specifically designed to fuel fast twitch (type II) muscle fibers for greater muscular power and gains. Fast Twitch helps increase post workout intensity while enhancing muscular repair. The harder the workout the more Fast Twitch can help. With Fast Twitch, you may run out of gym time before you run out muscle energy. Fueling type II fibers increases explosive power and speed. This translates into more sets, reps and weight lifted. Plus type II fibers have greater potential for overall muscle hypertrophy (growth).
