Lay with your butt at the top of the Isophit emblem, separate your legs, and bring them to the outer surface of the sidebars. Then raise your legs about 80˚ (depending on limb length). While keeping your knees locked out squeeze your legs into the sidebars. Your legs should be making contact just below your knee. Lastly, straighten your arms in front of you, make a tight fist, and crunch up to the bar.
