Which should you choose?
The Bent Knee Lying Twist needs no equipment and scales through leverage, tempo and reps. The Dumbbell Squat works each side independently and demands more stabilizer control. 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 glutes adapting.
