Not everyone can or wants to join the gym. My opinion is that the gym (for most people) is a waste of money. I am a fan of Beachbody products that allow you to get a great workout in the comfort of your home. I have used several at home DVDs and have gotten great results.
For those that are new to exercising or have limited mobility, I have found 5 easy in-home exercises that most people can use. I must advise everyone to please consult their doctor before beginning any exercise program, especially if it has been a while since working out.
