How to do it
- Select a light resistance and sit down on the ab machine placing your feet under the pads provided and grabbing the top handles. Your arms should be bent at a 90 degree angle as you rest the triceps on the pads provided. This will be your starting position.
- At the same time, begin to lift the legs up as you crunch your upper torso. Breathe out as you perform this movement. Tip: Be sure to use a slow and controlled motion. Concentrate on using your abs to move the weight while relaxing your legs and feet.
- After a second pause, slowly return to the starting position as you breathe in.
- Repeat the movement for the prescribed amount of repetitions.
Form tips
- Start light and own the movement before adding weight.
- Control the lowering phase — don't drop into it.
- Keep breathing; exhale on the hardest part.
- Stop if you feel sharp pain (different from muscle burn).
