My husband and I both do grow young and love it. Deron is fun to work with and a good motivator. The exercises are easy to follow and very effective. I would recommend it to anyone who wants or needs to get fit. My husband will be 80 in August and I am 77. We like the balance exercises, they are very helpful. The core and strength training are also good and fun. You ever have to get down on the floor, you do everything from a chair or standing by the chair. I have recommended it to friends and even told my doctors about it. If anyone is thinking about doing this program, my advice is to stop thinking and just do it. And as always…..Keep it movin’.
