Your Feet
Some moves require you to flex your feet. Others require you to point, or extend them. When flexing your feet, press through your heels to create length in your body, but keep your toes straight, not curled back toward your shins. When pointing your toes, create length by extending through your big toe, but don't overpoint, or overextend, by curling your toes toward your arches.
Your Neck
Don't arch your neck. Whether sitting or lying in position to do Pilates, you want a long neck. Concentrate on lengthening through the crown of your head and tuck your chin toward your neck slightly. Basic Ab Strengthener The benefits of this exercise are increased circulation as well as stronger abs, particularly your upper abs. Resist the tendency to work your upper body in this exercise. Relax your arms, and don't use them to pull your head and shoulders up. If your shoulders rise less than an inch, that's okay. Just do your best.
A. Lie with your back on the floor and your head and neck supported by a pillow or cushion. Your knees should be bent with your feet flat on the floor. Place your hands behind your head with your elbows out to the sides.
B. Press your abs down to your spine and exhale as you curl your ribs toward your hipbones. Inhale as you lower to the floor. Keep your navel flat throughout the exercise. Repeat.
