Difficulty: Moderately Easy
Step1
Lie down on your back on a comfortable surface with your feet extended straight out in front of you. Help to engage your leg and abdominal muscles during your pull-downs by flexing your feet, pulling your toes in towards your torso. Protect your back by keeping your abs tight and tucking your tail bone in slightly.
Step2
Hold one blade with both hands, positioning the blade so that it is horizontal to your body. Extend your arms straight up towards the ceiling, keeping your elbows bent slightly. Begin to shake the blade up and down towards your feet and up above your head, using rapid, short motions.
Step3
Drop the shaking blade slowly behind your head, coming as close to the ground as possible and then hold the position for 2 or 3 deep breaths. Bring the blade back up and drop down as close to your stomach as possible, again, holding and shaking for 2 or 3 breaths. Repeat the pull-downs, lifting up and down, for 1 to 5 minutes depending on your level of fitness.
Step4
Get a more advanced workout for your abs during your body blade pull-downs by lifting your feet a few inches off of the ground. Remember to keep your feet flexed and toes pulling in throughout the exercise.
