How to Perform

  1. 1

    Position your body for the exercise with proper alignment — joints stacked, core engaged.

  2. 2

    Move through the full range of motion with control. Bodyweight exercises reward quality over quantity.

  3. 3

    Focus on the muscle contraction at the hardest point of the movement.

  4. 4

    If the movement is too easy, slow down the tempo or add pauses. If too hard, use an assisted variation.

Common Mistakes

  • Using too much weight and compensating with other muscle groups. Isolation demands strict form over ego loads.

  • Rushing through reps without controlling the eccentric. The lowering phase should be 2-3 seconds minimum.

  • Cutting the range of motion short. Full range builds more muscle and healthier joints.

Pro Tips

  • Exhale forcefully as you contract your abs. This activates the transverse abdominis and makes the crunch or leg raise significantly more effective.

  • Think about shortening the distance between your sternum and your pelvis, not about moving your head or legs.
