Avoid harming your neck when doing squats by touching the bar to the tops of your shoulders. Holding it against the lower portion of your neck causes compression of your spine via the entire weight on just that area. This can most definitely lead to major muscle and spinal injury that could prevent further workouts.
Exercise during commercials. Long periods of television watching has been shown to encourage obesity. If you’re going to watch television, you can at least get moving during the commercial breaks. Do some light jogging up and down your stairs or skip rope for a few minutes until your program comes back on. This will help you to burn calories, even while doing something potentially unhealthy.
