Trainers Shaman DeArco and Mark Lebos share some of their best exercises for getting in shape.

Pushups — Chest

Beginner: Modify the plank position by dropping your knees to the floor and placing your hands shoulder width apart on the floor or against a sofa or coffee table. Lower chest down, push up and repeat.

Intermediate: In a straight plank position, push up from the floor or against a counter.

Advanced: With your hands on the floor, maintain the plank position and elevate your feet on a sofa, chair or an inflatable exercise ball to increase intensity.

Dips — Triceps

Beginner: With elbows bent behind you and hands pointing toward you on a coffee table or chair, lower your body down with knees bent at a 90o angle. Push up and repeat.

Intermediate: Straighten your legs, keeping feet on the floor. Advanced: Elevate your feet on a chair or exercise ball.

Single Arm Rows — Back

Grab a jug of detergent or a bowling ball. Place your left hand and knee on the surface of a sturdy chair or coffee table. Bend over, positioning your back perpendicular to the floor. With your right hand, pick up the jug of detergent or ball and lift slowly, bringing the object to chest level, back down and repeat.

Back Extensions — Back

Lie face-down with an exercise ball or ottoman under your hips, feet pressed against the floor or the wall for stability. All at once, raise arms in a reverse fly and arch your back up slightly. Use dumbbells, soup cans or water bottles as resistance weights.

Front and Lateral Raises — Shoulders

Using your resistance weights, raise arms out in front of you, down, out to the side and down again. Keep shoulders down, a slight bend in the elbow and don't raise arms above 90 degrees.

Three Way Lunge — Legs

Repeat forward, side and reverse lunges on each leg. Focusing your weight on the heel, lower the leg to no greater than 90 degrees. Don't let your front knee extend past the toe of your front foot.

Ball Squats -- Legs

Place an exercise ball against the wall and lean against it with the ball centered in the small of the back.

Beginner: With your weight in your heels and shoulders over your hips, squat down until thighs are parallel with floor and raise up.

Intermediate: Hold resistance weights by your side. Advanced: Add curls, or front and lateral raises, with resistance weights.

Single Leg Glute Press — Glutes

Beginner: On your back with both feet on the floor and knees bent, raise only your hips off the floor by pressing down through your heels. Lower down and repeat.

Intermediate: Extend your left leg parallel to the floor. Raise hips by pressing down through your right heel. Lower down and repeat on opposite side.

Advanced: Elevate feet on a step or fireplace hearth.

Crunch — Abdominals

Beginner: With your hands placed behind the base of your head, knees bent and feet on the floor, contract your abs while raising your head and shoulders slightly off the floor. Lower down and repeat.

Intermediate: Balance your back on top of an exercise ball, feet on the floor and crunch.

Advanced: With your back on the exercise ball, increase the intensity by holding a resistance weight or medicine ball while crunching.

Bicycles — Abdominals

With your back on the floor, bring your left elbow to your right knee. Switch to the opposite side and repeat.

Don't forget to warm up before any exercise and to stretch when you're done!
