"Save time at the gym with this 10-minute cardio/sculpt session: Hop on a treadmill holding a three- to five-pound dumbbell in each hand, and set the speed to a brisk walk. Do a one-minute set each of shoulder presses, biceps curls, triceps extensions, side laterals, front laterals and standing triceps kickbacks one after another as you walk. I's an amazing upper-body challenge that also gets your heart pumping. Do this series two or three times each week. As you improve, work up to doing four-minute sets."
"Adding wall sits to the end of every run will strengthen your quads, hamstrings and glutes, improving your speed and endurance. Lean against a wall with your feet shoulder-width apart, then squat until your knees are bent at 45 degrees. Hold for 30 to 60 seconds; work up to doing 10 sets. Add a challenge by including heel raises: Lift your left heel, then the right, then lift both together twice."
"Stay motivated using a fitness report card. Jot down these subjects: Cardio, Muscle Conditioning, Flexibility and Attitude. Set goals (for example, doing 10 "boy" push-ups) and grade yourself A through F at least four times a year. When you see how much you improve, you'll want to stay in great shape."
"Why pay someone to clear snow from your driveway? Besides burning nearly 400 calories per hour, shoveling snow develops muscular endurance and power. But be safe: Minimize the amount of snow on each shovelful, and bend from your knees and hips, not your back."
"Sit on a stability ball to strengthen your core, and keep dumbbells or exercise tubing at your desk. Squeeze in 12 to 15 reps of exercises like dumbbell curls, overhead presses and ab crunches; aim for two or three sets of each. This gives you more free time to fit in fun workouts like biking or tennis."
