Description

Crunches focuses on controlled movement and maintaining proper body alignment throughout the exercise. The goal is to create tension where needed while avoiding unnecessary strain or momentum. This helps improve movement quality, joint stability, and overall physical control.

Instructions:

  1. Lie flat on your back with your feet flat on the ground, or resting on a bench with your knees bent at a 90 degree angle. If you are resting your feet on a bench, place them three to four inches apart and point your toes inward so they touch.
  2. Now place your hands lightly on either side of your head keeping your elbows in. Tip: Don't lock your fingers behind your head.
  3. While pushing the small of your back down in the floor to better isolate your abdominal muscles, begin to roll your shoulders off the floor.
  4. Continue to push down as hard as you can with your lower back as you contract your abdominals and exhale. Your shoulders should come up off the floor only about four inches, and your lower back should remain on the floor. At the top of the movement, contract your abdominals hard and keep the contraction for a second. Tip: Focus on slow, controlled movement - don't cheat yourself by using momentum.
  5. After the one second contraction, begin to come down slowly again to the starting position as you inhale.
  6. Repeat for the recommended amount of repetitions.

Exercise FAQ

How often can I do this per week?

2โ€“4 times per week works for most, depending on recovery and total training load. Keep at least one easier day if intensity is high.

How hard should I push the pace?

Aim for a pace you can repeat. Start moderate, then increase intensity over time while keeping your technique consistent.

How do I avoid unnecessary impact or joint stress?

Use softer landings, keep your posture tall, and avoid overstriding. Quality movement reduces wear and tear.
