I'm pretty new at this myself, but wanted to let you know that it's o.k. to just jump right in and play, i.e. "click. click. click". It's how I have been learning my way around. So far I have encountered only splendid, encouraging and helpful people. Stop by and say hello. I hope you try isometric exercise, it's perfect for adults with mobility issues, chronic pain, have been sedentary for a while, or who tire easily. Yet even if you're at the top of your game, isometrics can give you the added edge towards meeting your goals, even if that is finishing a triathlon! You can find the team on my page, just click the "Isometrics For The Rest of Us" icon.
