Hate working out? This Exercise is a very simple movement; you can do in your living room or office. This series of movements will take about 12 to 15 minutes. You can do them three to five times per week. Your entire body will be stimulated and you will feel rejuvenated, without all the added stress of having to go to the gym. After completing one movement, immediately continue with the next one. After you've completed all the movements, perform them one more time. Attempt 20 to 25 repetitions of each movement. Don’t worry if you can’t perform all the reps. It will come.

OK, lets’ go.

1. PUSH UPS

Lying face down on the floor, place your hands a little wider than shoulders-width apart. Your thumbs should be lined up with your chest. Your toes should be curled under, and your feet should be hip width apart.

Be sure to maintain hip alignment throughout the entire range of motion. Avoid sagging in the midsection of your body. Contracting the chest muscles, raise your body until your arms are fully extended.

2. CHAIR SQUATS

Perform this exercise with the aid of a sturdy chair. Stand in front of the chair with your back toward the chair and feet shoulders-width apart. Keep your head up as a natural extension of your spine.

Begin to sit in the chair, lowering your body until your legs are at a 90-degree angle. Contracting your quadriceps (front part of the thigh), slowly return to the starting position, stopping just short of the legs being fully extended. Keep a slight bend in the knees.

3. AB CRUNCH

Lie on your living-room carpet on your back. Make sure your lower back is relaxed against the floor during the exercise. Bend your knees until your legs are at a 45-degree angle. Keep both feet on the floor and place both hands crossed on your chest. Contracting the upper abs, raise your head and upper torso off the floor until your shoulders are slightly lifted.

Slowly return to the starting position, stopping just short of your head touching the floor. Focus on really contracting your abs during the movement.

4. CLOSE STANCE WALL PUSH

Stand facing the wall with your feet shoulders-width apart. Place your hands on the wall so that your fingers are slightly lower than your shoulders. Your hands should be close enough that your thumbs and index fingers form a triangle. Your feet should be a distance from the wall that forces your body to be at an angle slightly greater than parallel. Bend your elbows downward and lean your upper body toward the wall, making sure to project your chest forward. Your arms should be supporting your body.

Stop the motion when your face nearly touches the wall and your chest touches your hands. Contracting the triceps muscles, slowly return to the starting position, stopping just short of the elbows being fully extended.

5. AB VACUUM

In a seated position, exhale all the air from your lungs. After completely exhaling, pull the abdomen in inward and hold for 20 to 30 seconds. Continue to breathe lightly through your nostrils, but make sure you are pulling your abs in as if you are attempting to make your abs and back touch.

This exercise works the transverses, the main muscle that pulls your abs in. In fact, it's the most effective exercise to flatten your stomach.

There you have it -- five exercises performed for two cycles in just 12 to 15 minutes. Upon completion of the two cycles, you will eventually perform 50 total repetitions of each exercise (except for the vacuum).

You'll begin to notice a tighter feel in your muscles in a few weeks, and you will naturally perform more reps as time progresses. All in 12 to 15 minutes.
