How to do it

Lie on a decline bench, secure your feet, and perform crunches by lifting your upper body toward your knees, engaging the core.

  1. 1Feel your upper and lower abs firing as you curl up on a declined bench
  2. 2Keep your core tight and controlled throughout the full range
  3. 3Exhale as you crunch to intensify the contraction

Common mistakes

  • Avoid pulling on your head or neck
  • Don't let your feet lift or use momentum to get up
  • Avoid arching your lower back as you descend; maintain contact with the bench
