- Attach cable ankle straps to both ankles, then attach ankle
straps to cable. Lie supine on floor or mat, back far enough
so cable is taut. Grasp support behind head.
- Raise legs by flexing hips until fully flexed. Raise hips
from floor by flexing waist. Return until waist and hips are
extended downward. Repeat.
- Rectus Abdominis and Obliques only contract
dynamically if actual waist flexion occurs. With no waist
flexion, Rectus Abdominis and External Oblique will only act
to stabilize pelvis and waist during hip flexion. Waist flexion
will occur earlier in lift if legs are straighter or Hamstrings
are not that flexible. See Spot
Reduction Myth and Lower
Ab Myth. Also see Cable
Lying Straight Leg Raise.
