1. Engage in circuit training to maximize your workout time and results
2. Drink something like Contrex® (a mineral water with magnesium and calcium) to replace essential fluids, curb hunger and provide much needed calcium
3. Eat foods high in nutrients—don't try and spike your energy with high sugar snacks and caffeine. It might work but it doesn't help you at all.
4. Incorporate interval training into your cardio
5. Perform full-body workouts for the best health benefits. Avoid the "spot-reduction trap". Don't just work on your abs or your arms.
6. Use combo moves to maximize your time
7. Vary your workouts so you don't get bored and give up.
8. Choose an event as a fitness goal, like a race or a walk for a good cause.
9. Workout with a partner. Nothing guilts you into going to the gym like having to meet your friend there...
10. Keep a simple food and exercise journal so you can track your progress and have a record of just how much you accomplished.
