this product was easy to set-up and easy to use....feels very sturdy while i am working out and makes doing sit-ups and crunches much easier to do....it keeps my legs and body comfortably locked in position so the only muscles that get worked are the abs...i weigh 220 lbs and the bench is solid under me, no rocking or creaking...a very good product to add to your daily workout routine.
Easy to put together. No need for 2 people like directions state. I originally purchased just to use as weight bench. Love it as an ab bench...works my ab muscles in ways I didn't expect! Very compact. I store it behind my treadmill that is a rollaway (also purchased on O). Great purchase/quality...you won't be disappointed for the money!
