The objective of this exercise is to make Pilates work the obliques, the alignment and stability of your posture.
Begin by lying down on one side. Keep the lines of the shoulders and hips perpendicular to the ground. Stretch your legs in the body axis, the arm above the head. Place the head on this arm. Place the upper arm to the chest, parallel to it.
Now exhale while returning to the belly. Then breathe in while contracting the abdominals and lifting both legs to the sky.
Exhale and lift more than the leg, without putting the leg below the ground.
Finally, inhale and pull the upper leg on the lower leg.
At no time should you use the arm resting on the ground to lift you. Keep the right upright when you get abs.
Try to do them in 3 sets of 15 movements (45 movements in total). If you are accustomed, made 80 movements.
Pilates is good but to get fit in real life you must also sweat out. Programs like TurboFire, P90x, Insanity, Tae Bo will make you fit.
