Decline Bench Knee Raise Instructions

  1. Grab a decline bench and set the angle to around 30 to 45 degrees. Lay on the bench backward, with your head on the highest end.
  2. Hold onto the pads above your head for stability.
  3. With your feet and knees together, point your legs out straight so your body forms a straight plank. Your legs should not be resting on the bench. This is the starting position.
  4. Execute by slowly pulling your knees up towards your chest as high as possible.
  5. Then extend your legs back to the starting position. This is one rep.
  6. Repeat for desired reps.

When I do these I lift my butt up. I was always taught this way it engages/tatgets the lower abs.

Correct me if I'm wrong, but I think you really need to contract your waist more at the top of the exercise, otherwise you're really only working out the iliopsoas.
