I'm aware that not everyone has the privilege to workout in the comfort of their own home but havin exercise equipment such as an elliptical or treadmill, & strength training DVD's, like P90X or Jillian Michaels' is so convenient. Havin the option to simply go workout in your basement with your favorite series/show/movie on makes it that much easier to workout. Plus, not havin to go outside & drive in the cold makes it more motivating to get your fitness on bc you don't have a reason not to.
I understand that purchasing an exercise machine is costly but memberships can be quite spendy too! I got a Gold's Gym Stride Trainer 500 (Elliptical) on Craig'sList for $125, P90X on C.L. too for $60, & I have both of Jillian's workout vids for $10each. My membership at Lifetime is $60/month.
