So I jumped right in and did 3 sets of 15 concentrating on form and extension. I had to dial it back as I was starting to strain some of my lower ab muscles, I still use it regularly but I needed to build a bit more before jumping on as many reps and sets. Also the wheel is high quality and so your aware it only rolls in one direction when you start out as it is loading a spring as you roll out, so start with the wheel close to your body otherwise you can run out of travel on the return. Great tool but easy to over do it as your building ab strength, to be fair I work out no less than 3 days a week and often 5 or more times a week.
I prefer my workout mat to the knee pads that come with it though. I did buy a cheaper ab carver before and returned it, but I totally like this one. It's bigger sized to be more stable, with spring inside to assist working out, and the whole thing is still quite light.
MY husband bought this to firm up his tummy a little, getting close to 40. And with diet, this this has made cuts in his stomach, and he's not even sore. It's amazing.
There were also beginner directions that made it much easier for my first time. Anyway, you absolutely feel the burn in every movement. After our first day, my boyfriend and I couldn't sneeze or cough without feeling sore lol but the good sore, that makes you feel accomplished. I definitely recommend this product. You can tell it's working in the first week. Just make sure you do ab stretches before and after! My friend was just messing around trying it and ended up pulling a muscle. So stretching before and after is important. Overall, I think it's worth the price. I love it!. I love this thing! The first time I used it though I thought it was too hard lol but I went on the website and downloaded a pdf for the 21 day workout.
Fits well. Bottoms just a tad big but top was perfect! I’m 5’9, 180 lb, D cup, full butt. I ordered size large. Love the strappy design. Functional yet sexy. Only complain, which I overlook because I love this suit, is a little bit of the rubber sticks out of the band on top and pokes into my back. I only notice when I wear the suit all day.
