Gravity Crunch

Model #3178


  • Resistance is set by adjusting the length of the chrome-plated foot bar.
  • Foot bar is the same diameter as an Olympic bar, so plates can be loaded for extra resistance.
  • Fully welded frame for maximum rigidity, strength, and durability.
  • Pillow block bearings are smooth, durable, and feature grease fittings.


Crunches and sit-ups are regarded with the same amount of enthusiasm as dental cleanings. The Gravity Crunch provides a refreshingly different means of strengthening those abs without requiring the users to get on the floor.

For quality, Legend gave the Gravity Crunch a fully welded frame for the ultimate in rigidity and minimal maintenance, then added thoughtful touches like grip tape on the stepping surfaces, tough yet smooth pillow block bearings, chrome-plated adjustment surfaces and a high quality pad made with high density foam and 32 oz. upholstery that is top-stitched for durability.

For functionality, the difficulty of the exercise can be adjusted by shortening or lengthening the reach to the chrome-plated foot bar. The lower the foot bar, the lower the user’s hips are from the pivot point, which increases the effort required to complete a crunch. The user keeps the upper body steady and upright with the extra long, foam rubber coated handles. For extra versatility, the round foot bars can accommodate weight plates.
