You've all heard me advocate for out-of-the-pool resistance training in the form of weights, but I wanted to pass along this article as extra incentive. Even using bands & body weight can be an effective way to stave off Type II diabetes, osteoporosis and other issues. Plus, you'll see benefit in the water in the form of more explosiveness off the walls, block and general strength.
Please consider incorporating weight training of some kind into your weekly regimen. If you need help with ideas, please let me know!!
