The American College of Sports Medicine recommends that healthy adults under age 65 should do eight to 10 strength training exercises twice a week, along with 30 minutes of moderate cardio, five days a week, or 20 minutes of vigorous cardio, three days a week. But just knowing what you're supposed to do doesn't make doing it any easier. Where are some ways to help you through your workouts.

Count Backwards:Try counting backwards from the total number of reps you're doing instead of counting up from zero. This makes the finish line seem like it's getting closer, rather than a looming number in the distance till your final rep.

Mix it Up: Add as much variety as possible to your workouts. Cross training, or even just switching exercise programs every few weeks. This helps keep your body guessing and challenges it to adapt and improve, as opposed getting into a rut and hitting a plateau.

Eat Right: Limit yourself to small meals and/or snacks one hour before you exercise,. After your workout, eat a meal that contains both protein and carbohydrates, such as apples and cheese, within 90 minutes after you exercise.

Get Out & Play: Not only are sports and recreational games fun, but it gives you a chance to socialize with other like-minded people and an opportunity to also burn calories.

Bring a Buddy: Having friends along doesn't just make exercise more fun and it also makes you accountable. If you cancel on your workout buddy, she's going to want to know why. Positive peer pressure, plus the extra fun factor, will help keep you on track.

Adapt to Your Environment: Adapt your workouts to the conditions. If
it's such a pretty day that you can't force yourself to go into the gym, don't.Get your cardio in by running or walking outside instead, and use small hand weights, resistance bands or body weight exercises for strength training.
