Stand with your weight on the balls of your feet, heels slightly lifted, knees softly bent. Take small hops, rotating your clenched hands by your hips as if jumping rope
Standing Crunch- Boost energy while working your legs, obliques, and back
Stand with arms straight above your head. Lift your right knee out
to your right side as you bring the right elbow to meet it. Return to
starting position, then repeat on the left. Keep alternating.
Stair Climbing- cardio and build leg strength
On your way to pick up lunch, hit the nearest staircase and climb two flights, taking the stairs two at a time to maximize the cardio workout while also building leg strength. Head back down the stairs with quick, light steps, then repeat until five minutes are up.
Midafternoon:
Jumping Jacks-

Focus and energize before a big meeting
Hop feet out and raise arms to shoulder height; pause. Jump feet together and lift arms above your head; pause. Hop feet out and lower arms to shoulder height; pause. Bring feet together and arms down to sides. Repeat.
Arm Circles- When the afternoon slump hits, boost your circulation and release shoulder stress.
Standing or sitting tall, extend arms out to your sides and start making large circles, working down to small circles. Reverse direction. Repeat with arms to the front and above the head.
Office Laps
Refresh your mind and body with a fast walk around the office, outside the building if weather permits, or up and down the hallways. Walk quickly, pump your arms, and resist the temptation to stop and chat until your five minutes are up.
After Work:
Vacuum
Everyday activities count as exercise, too: You can burn more than 200 calories an hour -- and scratch a to-do off your list -- by vacuuming. Tackle one or two rooms, bending to pick up stray socks and moving quickly as you clean.
Mall Walk
Turn your holiday gift buying into an exercise stint by taking a full lap around the mall before starting to shop. You will not only add another five-minute interval to your day, but also get a preview of all the stores -- so you'll know where to go and shop more efficiently.
Evening:
Shake It Off
Release tension as you bump up your heart rate by putting on a favorite five-minute song and dancing however the mood strikes. Stevie Wonder's "Boogie On Reggae Woman," Justin Timberlake's "Senorita," and Madonna's "Vogue" all fit the bill.
Spine Stretch Forward
Sit with legs slightly bent and feet just wider than hip-width apart. Inhale, sitting tall. Exhale and draw your navel in to the spine, making a C shape with your back as you fold forward, reaching for the toes. Inhale and roll back up. Repeat.
