This is a great exercise for strength and hypertrophy, and it'll give you more time under tension in your ab routine.

You'll need a band and a GHR (glute-ham raise) station. Secure the band under the machine or to a dumbbell and wrap it around your torso.

You're going to use a slow and controlled movement here. No flailing around. Notice this is a "partial" movement.

  • Come down only until your torso is parallel to the floor.
  • Stop at the top just before you lose tension in the abs.

Think "time under tension" not reps.
