Which should you choose?
The Barbell Split Squat lets you load the heaviest weights and progress in small, steady jumps. The Weighted Sissy Squat adds external load to a bodyweight pattern for direct overload. 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.
