Bosu Trainer and home gym fitness equipment

Core training would be where I'd suggest anyone start with an exercise program. I believe that one reason my joints ache is that I don't have enough muscle structure to support them. The Bosu ball costs about $129, but is worth every dime, in my opinion. The professional version is what they have in gyms and can be bought through Amazon. For my "home gym", I have that and the Gold's stability ball, a jump rope, and 2.5 lb. ankle/wrist weights...everything but the Bosu ball is from Wal-Mart. The Bosu ball and the stability ball each have instructional CDs. That's all there is too it. You don't need treadmills, steppers, weight machines or anything else to get started.
