Reverse Crunch
HOW TO DO IT
  1. 01Lie on your back with the arms flat beside you and the knees bent over the hips.
  2. 02Press the lower back into the floor and exhale.
  3. 03Curl the pelvis up and in so the hips lift a few inches off the mat.
  4. 04Lower slowly until the hips touch down, keeping the back flat throughout.
COACHING CUES
  1. 01Lift the hips, not the feet.
  2. 02Lower back stays printed on the floor the whole set.
  3. 03Exhale on the way up — the breath is what gets the ribs down.
COMMON MISTAKES
  1. 01Swinging the legs to generate momentum, which moves the work into the hip flexors.
  2. 02Letting the lower back arch on the way down, which is where most people feel it the next day for the wrong reason.
  3. 03Pulling with the neck or the arms instead of curling from the pelvis.

Note: Reference material, not a prescription. Load, volume and whether this movement suits you at all depends on your assessment — if something hurts, stop and get it looked at.
