    Why won't the handle turn to select the desired weight on my Stairmaster TwistLock Dumbbell?
    • B
      Brenda BenitezJul 31, 2025
      If the handle on your Stairmaster Fitness Equipment won't turn to select the desired weight, make sure the handle is fully depressed down into the cradle. The locking mechanism won't release until the handle fully engages the cradle. Once engaged, the handle should turn freely. Weight selection changes are impossible without full handle engagement.
