Some quick calisthenics are good for flexibility and blood flow, but they can also provide a boost of energy. The next time you feel yourself lagging, try these three stretches for a pick-me-up.
Sit in a chair and place your hands on the back of your head. Press your elbows backward to open your chest up. Stay evenly seated on the chair and move your right elbow towards the ground, bending at the right side of your waist, then return to center. Next move your left elbow to the ground, bending at the left side of your waist, and return to center. That is one rep. Do two sets of 10-12 reps.
Standing up, slightly bend at the knees and reach your hands towards your toes. Hold 15-30 seconds. Return to standing. Repeat 2-3 times or as necessary.
Sitting or standing, reach your right arm straight across your chest and hold your right elbow with your left hand and hold for 10-15 seconds. Return to center. Now reach your left arm straight across your chest and hold your left elbow with your right hand and hold for 10-15 seconds. Repeat as necessary.
