End your workout routines with great cool down stretch exercises to maximize calories burned while cooling down your muscles.

Workout Routines # 10. End with an invigorating stretch

Stretching is as important after running or walking as it is after weight lifting. A study found that regular stretching can increase your strength by up to 19 percent when interspersed between weight-training exercises. With additional muscle you'll have more calories burned throughout the day.

To keep your heart rate up while still stretching your whole body, try doing a series of 10-12 Sun Salutations, yoga's most aerobic move (it incorporates poses that flow from one to the next).

Here's a fast-paced variation used in many Ashtanga classes:

1. Stand with feet together and arms by sides. Inhale as you reach arms up overhead until palms touch. Look at hands.
2. Exhale to Forward Bend, knees slightly bent and hands to feet.
3. Inhale as you bend left knee and extend right leg back to a lunge. Keep hands on either side of your feet.
4. Exhale and bring left leg in line with right, keeping head, torso and legs in one line for Plank pose.
5. Lower legs and torso to floor, then raise head, neck and shoulders into a long Cobra pose.
6. Push onto hands and feet, lifting hips to the sky to form an upside-down V. This is Downward-Facing Dog.
7. Return to Cobra pose.
8. Bring right foot up and lunge, keeping left leg straight behind you.
9. Bring left foot up to meet right and return to Forward Bend.
10. Inhale; sweep your arms out and up.
11. Exhale and come back into the first standing posture, also known as Mountain pose. Repeat, moving quickly but without sacrificing your form or breathing.

Boost in calories burned: You'll burn another 50 calories after your workout routines.
