Convertible Ab Wheel Roller with Large Knee Mat for Core Abs Rollout Exercise. Double Wheel Set with Dual Fitness Strength Training Modes at Gym or Home

Perfect kit to get you started on improving fitness and toning, sturdy equipment and easy to use and love the mat for knees.

The product does exactly what it's supposed to do, it's stable, the foam grips are comfortable and it's a bonus to be able to progress from double to single wheel.But there's no way those foam grips were getting on the bar without lube. I tried without and it felt like the foam grips would rip immediately.Another reviewer mentioned the instructions suggested wetting the bar with water before twisting on the grips. Firstly, my instructions didn't mention this. Secondly, you may get the grip on a wet bar but I don't think those grips are coming off in one piece when you come to convert from double wheel to single wheel.Do yourself a favour and spray the ends of the bar lightly with WD40 before twisting on the foam grips for the first time. Then hopefully there will still be enough WD40 under the grips when you come to convert the wheels to avoid ripping the grips.Have some kitchen roll standing and make sure you wipe up any WD40 residue after you've assembled, so the grips aren't left slippery.With the WD40 spray, it installed in seconds and was completely safe to use after the residue was wiped away.

Well I seem to have bought a new torture device, this contraption when used correctly will leave you aching and wondering what you did wrong to treat yourself so badly 😁In all seriousness, what a bargain! Really well made, includes the mat for your knees and has 2 modes, dual wheel for beginners and single wheel once you’ve mastered it (will that ever happen for me 🤔) This really works your abs and the first time you use it you’ll realise just how fit and flexible those YouTubers showing it off are.. and how unfit and stiff you are 😭 Practice makes perfect though and I can stretch a little bit further each week 🏆 so I will persevere!Good luck fellow sufferers 😁👍

This product met all my expectations and requirements. You can change between gaps to make it more stable and easier or central ( wheels interlocking) to make it slightly harder.I read about people giving it lower marks cos they can't get grips on!? It's them that need to get a grip.Little bit of olive oil, coconut, face cream, ky jelly before putting them on and they fly on easy. Didn't think that would be hard to figure out but.... There ya go.Anyway awesome product and my abs and core know all about it! I can only do it from kneeling atm but when core and abs strengthen I'll do it from standing to horizontal. Hard AF but seen it done.Effort and consistency = Abs and strong core.I recommend having bought some cheap rubbish in past.

It is easy to use. Be careful as it will stretch your abdomen muscles. Look at videos before using as it is recommended.

Not bad, but should be a way to lock the devices together and fix the handle covers in place

A useful tool for using at home. Pretty solid, and comes with either two wheel (bit more stable) or one wheel alternatives. Main reason for 4 rather than 5 stars is the tiny mat for kneeling on it is about 14 x 6 inches and 1/2 inch thick. Probably best to replace with something like folded yoga mat, pillow or (clean) gardening pad. The rubber sleeves are difficult too get on unless you follow the instruction to put water on the shaft and inside the sleeves, then it is relatively easy to put sleeves on with screwing motion. Instructions say use a hairdryer to warm up sleeve at 60c. Which I am guessing is about medium as my hairdryer doesnt show temperature settings. So far no sighs of marking the carpet which is a big plus.

Good quality, limited assembly required, is very comfortable to use on the hands, not so much on the abs but I guess that is the whole point!
