Oblique Crunches - On The FloorOblique Crunches - On The Floor

A floor-based oblique crunch where you lie on your side and crunch upward, isolating the oblique muscles on each side of the abdomen.

Instructions

  1. Start by lying on your right side with your legs lying on top of each other.
  2. Keep your knees bent slightly for comfort and stability.
  3. Place your left hand behind your head, supporting your neck gently.
  4. Once in this set position, begin by moving your left elbow upward as you perform a crunch.
  5. The main emphasis is on your obliques, so focus on that area.
  6. Crunch as high as you can, holding the contraction for a second.
  7. Slowly drop back down to the starting position.
  8. Complete all repetitions on one side, then switch to the other side.

Tips

  • Breathe in during the lowering phase and out during the upward crunch.
  • Move deliberately and with control to maximize oblique engagement.
  • Keep your hips in place; only the upper body should move.
  • Support your neck with your hand but don’t pull excessively.
  • The floor-based position provides great stability and form control.
  • Perform equal repetitions on both sides for balanced core development.
  • When bodyweight becomes easy, try holding light weight plates.

Recommended starting values

Sensible novice starting points for each goal, for a lifter aged 25–40. Scale down for smaller frames or older lifters. Treat the first set of any session as a discovery set.
