Plan ahead for your workout routine. For example, if you exercise in the morning, set out your clothes before you go to bed. If you go to the gym in the afternoon, pack your bag in the morning. This way, when it's time to exercise you're ready to go and have no time to make excuses.
When you are planning your gym regimen, make sure that you include cardio as often as possible. An hour on the treadmill will not only help you to tone your body, but can reduce the excess fat that you have on your stomach, arms and legs. This will go a long way to improving your appearance.
