Which should you choose?
The Backward Jump needs no equipment and scales through leverage, tempo and reps. The Bosu Ball Squat adds an unstable surface that raises core demand. If your gym has both options, neither is a wrong choice: pick the one that feels strongest through a full range, and swap after 6 to 8 weeks to keep the quads adapting.
