Car rides, airplanes, desks: We spend so much of our time sitting, why not make the best use of it and get those legs in shape?
Raise your heels to work your calves. With a carry-on bag, a stack of magazines, or a heavy Sunday paper on your lap for resistance, plant the balls of your feet, lift your heels from the ground, then lower them.
Try toe raises, too. With your heels on the ground, lift your toes upward. Either hold them in place or raise and lower them.
Work those thighs with leg extensions. Placing your feet underneath the seat in front of you for resistance, try to lift your legs as you contract (squeeze) the muscles of your thighs. This can also work without a seat in front of you. Simply extend your legs forward and hold.
Lean forward as though you're going to get out of your seat. When your rear end is barely off the seat, hold that position. See how long you can hold it, using only your arms for balance.
Strengthen your inner thighs. Place a pillow, blanket or small carry-on between your feet. Try to lift the item off the ground and squeeze your legs together at the same time. You can also place the blanket, pillow or other soft object between your knees and squeeze.
Burn those buns with a gluteal squeeze. While sitting, squeeze the muscles of your rear end. Hold, then relax.
