I love ab wheels and this wheel has not let me down.

Have yet to embrace my feet, but from my knees I have been pleased.

One of the best tools for developing your abs and core. Much better than crunches! Well made and easy to use (but not easy to do), highly recommended.

Torque Athletics(www.torqueathletic.com) "Ab Grinder" is far better constructed(like comparing a Ford Ranger truck to a Peterbuilt) and has a lower center of gravity allowing a more productive workout.

This is another extraordinary piece of equipment made by Lifeline. The simple fact is that there are instances where only a specialized piece of exercise equipment can do the best job in hitting certain muscles in a certain way. There is no substitute for Power Wheel pikeups, or certain animal movements. I consider the Power Wheel to be one of the top 3 pieces of exercise specific equipment a person could have. Plus it can be used as an ab wheel....two birds with one stone. And it is $25 less than the "Ab Grinder."
