Yes4All Glute Hamglider Black - Commercial and Home Gym Multifunctional Roller - Hamstring Curl Abdomen and Leg Workout

The item is sturdy and strong. The wheels are standard rollerblade wheels with bearings which work well. The problem is that the bolts do not work well, when tightened they lock up and when loosened to adjust become unstable. I hacked the wheels by buying decathalon spacer and bolts set for in line skates and replaced the axel and spacers . Works perfectly with the change. If you buy do consider making the change. Seller should include them in the product

Worth every cent.

Solid build. This thing’s a tank. The wheel axle could definitely be better but it wasn’t really an issue for me. I tossed the lock washers and used a single flat washer on each wheel instead (on wheel side between wheel & frame). Wheels run smoothly as long as you don’t tighten completely as instructed. Lock nuts don’t seem to be loosening. Of course I’ll upgrade to longer bolts if needed but so far so good. Buy this item especially if it’s on sale. Incredible piece of gear for hamstring curls and chest flyes.

This is such a good hamstring butt workout! I use this at my home gym in place of hamstring curls. It rolls smoothly in the floor, even over the little grooves in the floor mats. I’ve been using it for a while now and looking for ways to add more resistance, as my strength is building. I started putting a dumbbell on my hips to make it a little harder. Seems to do the job!

love this product but am gutted at the same time ,,assemble this as guided and found out it wont roll so try loosing the bolts abit but then the wheel miss in line when you put presser on it ,,had to buy diffint bolts with washers just so a can use it
