IT'S ALL RELATIVE
As a person who, 25 years ago, could do over 2000 sit-ups in 1 1/2 hrs. I now find myself with much less energy and a more sedentary job and 60 years old. I have shunned all the other "hide-under-the-bed" exercise scams. I took a chance on this one and must say that the construction and theory are not bad in practice. For someone who wants to watch TV/listen to music/meditate while springing back-and-forth, I notice positive ab muscle tensioning. It's easy to sit there and rock; and before you know it you're rocking more and more, and easier and easier. Since the abs are the key to lower back muscle strength how can this tiny device, at a mere $100 hurt more than the first few days? This item will NEVER be under my bed. I'll wear it out and ask for one made from stainless steel! I think it's the best ab device available, if you need a device to motivate you to do ab exercises. Apt dwellers, this I recommend for you.
