Which should you choose?
The Barbell Standing Twist lets you load the heaviest weights and progress in small, steady jumps. The Cocoons need no equipment and scale through leverage, tempo and reps. 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 abs adapting.
