I keep these handy so I won't forget to do my routine. I cannot do some of the exercising suggested with the product because of trouble with knees, I'm 78.But I feel stronger, refreshed and ready! after a few minutes with the weights. Then I walk for the strenthening of my legs. I hope to work up to the 4 lb weights. Besides, they are pretty. Amazon.com sent these out fast. That's another good thing I appreciateRose
