Overview

This is a foldable sit up bench built around a steel frame with three spring loaded resistance levels (35, 44 and 57 lbs) for ab, leg raise and push up style exercises at home. Rated for users up to 220 lbs, it suits apartment dwellers wanting one compact station instead of separate ab and bench equipment.

The spring resistance system is the actual mechanism here, not just padding: switching between the three preset levels is how a sit up turns into a harder crunch or a leg raise. Because it folds flat, storage under a bed or sofa is realistic, but the 220 lb weight rating is a real ceiling worth checking against your own weight before buying.

  • Steel frame, foam cushioned
  • 3 resistance levels: 35, 44, 57 lbs
  • Folds for compact storage
  • US patented design

Who it's for

Suits beginners and casual home exercisers who want core, push up, and leg raise moves in one folding unit without a full gym setup. Not built for anyone over 220 lbs or lifters wanting free weight loading.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out
  • Folds flat for storage under a bed or sofa
  • Three spring resistance levels for scaling difficulty
  • Foam cushioning on frame contact points
What to check first
  • Fixed 220 lb weight capacity limits who can use it
  • No free weight loading, resistance is spring only

Performance notes

Resistance comes from three spring settings (35, 44, 57 lbs) rather than adjustable plates, so intensity changes happen by switching springs, not adding weight. The steel frame and foam cushioning are meant to keep the unit stable during sit ups and leg raises, and the spring mechanism is built to move quietly enough for use in front of a TV.
