What the RSD one-handed training bat is built for The RSD is the ideal weight to facilitate better use and growth of a hitter's forearm strength. That includes both the bottom hand and the top hand. The shortened length isolates each hand individually. The hitter can feel where their swing is breaking down and fix it. The RSD has found its way into professional organizations and become a favorite among pro athletes. Many use it as part of their daily routine. How to use the RSD in practice The RSD works in several drill types: One-handed drills. Take swings with the top hand alone, then the bottom hand alone. This isolates each hand's path through the zone. Soft toss. Use the RSD with a soft toss feed to focus on barrel control and grip strength. Short-distance overhand BP. Move closer to the feeder for high-volume reps focused on contact quality. Workout finishers. Add a set to the end of a hitting workout to lock in forearm engagement.
