Which should you choose?
The Balance Board needs no equipment and scales through leverage, tempo and reps. The Smith Chair Squat fixes the bar path so you can push close to failure with less balance 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.
