Crunches without the knee strain: the low-impact design guides your movement so you can build your core without hurting your joints
-
No wobble during your set: the coated frame with reinforced support bars keeps you balanced through every rep
-
One machine, your whole core: this ab machine works your abs, arms and legs together instead of isolating just one muscle

-
Built for real body weight: rated up to 220 lb so most adults can train with confidence on this crunch machine
Traditional crunches on a hard floor take a toll on your neck and lower back, and this ab machine changes that — the assisted-resistance system supports your motion so you can work your abs, arms and legs without straining anywhere you don't mean to. It's built for beginners easing into a routine and for regulars chasing a safer, more controlled crunch, and the low-impact design keeps the strain off your knees and joints the whole time.

This ab trainer runs on nothing but your own effort — no batteries, no cords — so it doubles as sit up machine time whenever you have a few free minutes. The coated, reinforced frame folds to about 1.6 x 1.3 x 0.8 ft (0.5 x 0.4 x 0.2 m) for storage, works for men and women, and holds up to 220 lb (99.8 kg), so it functions as real ab workout equipment for stomach exercise equipment routines without giving up permanent floor space.
