How each one starts

  2. Engaging your abs, lift your legs and upper body off the ground simultaneously, reaching your hands towards your toes.

  1. Sit on a stability ball with your feet shoulder-width apart and flat on the ground.
  2. Hold a weight in one hand and place your other hand on your hip.

Decision

Which should you choose?

The Band V-Up gives accommodating resistance that peaks at the top of the range. The Weighted Side Bend (On Stability Ball) 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 abs adapting.

Can I do both the Band V-Up and the Weighted Side Bend (On Stability Ball) in the same program?

The primary muscle is the same: the abs. Supporting muscles differ slightly — hip flexors for the Band V-Up versus obliques and lower back for the Weighted Side Bend (On Stability Ball).
