A dedicated trampoline made specifically for batting practice!! By using a trampoline with an unstable base, you can strengthen your lower body, core, and sense of balance. It's effective for practicing swings that utilize the lower body properly to avoid arm-swinging. 【Most effective when used barefoot or with socks】 Removing your shoes creates a more unstable condition. The batting trampoline is less stable than a regular trampoline. By repeatedly practicing batting on an unstable base, you can develop a powerful swing that effectively uses your lower body!
