How to do Decline Bent Leg Reverse Crunch

  1. Begin by lying on a decline bench with your head at the higher end and place your hands on the side edges of the bench for stability. Bend your knees at 90 degrees and lift your legs so your thighs are perpendicular to the bench and your lower legs are parallel to the floor.
  2. Engage your core and lift your hips off the bench, curling your knees towards your chest while keeping both legs bent.
  3. Lower your hips back to the starting position with control, keeping your knees bent at 90 degrees. Repeat the movement for the desired number of repetitions.

Form tips

  • Keep your core engaged throughout the exercise to maintain stability and support your lower back.
  • Avoid using momentum to lift your hips; focus on using your abdominal muscles for the movement.
  • Breathe steadily throughout the exercise, exhaling as you lift your hips and inhaling as you lower them.
