An advance on the classic "pencil routine" advocated by some brass teachers, Chopsticks are a way to help strengthen your chops while away from the instrument. Typically done as a 15 minute routine. Pilot tested with University of Arizona students, this kit incorporates a specialized exercise set that reduces the stiffening effect that simply holding a pencil can sometimes cause. Shown to make improvements in range, endurance and control. Includes five stainless steel weights, Methodology Booklet and Deluxe Clip-On Bag. Pro version also contains a set of three supplemental weights for adding weight and balance.
