Which should you choose?
The Band V-Up gives accommodating resistance that peaks at the top of the range. The Machine Seated Crunch fixes the movement path so you can push close to failure with less skill 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 abs adapting.
