It's two months later and this ab trainer is still holding up very well. If you use this thing regularly, it will definitely strengthen your core. And do a great job of it. it's helped me get a nice, flat and strong set abdominal muscles. For not that high of a price.

I have a back injury that prevents me doing traditional situps.This thing really gives you a work out far beyond what I expected. Even though it's light weight, it seems to be engineered to take the forces, I'm 5'11" and 220lbs and haven't bent the bars or made anything creek yet.

It’s easy and it works! I have in my living room in front of the TV & I use it several times during the day. Started out with 5 reps. Now I do 5 reps at least 20 times a day!
