I'm overweight by 60 pounds with artificial knee. Have not exercised in more than 4 years. Would like to start with something easy.Quick Core Foundatio

You're welcome :)

Just make the first step and start working out. You might even enjoy it.

You can find people to keep you motivated. Having a pusher is the best you can do, works for me.

Search for Monica Vela :) she is a good motivator..
