I came up with a great ab exercise today, very challenging! It requires a paralell bar station with overhead handles, usually used for hanging knee or leg raises.

1) Grip the handles as if to do hanging leg or knee raises. make sure your grip is FIRM, or else this can go badly!

2) Swing your legs up untill your legs and torso form a perfect vertical line from the ceiling to floor, as if in a handstand position. Your upper body and head will be slightly tucked in, your upper back and back of head should be near parallel to the floor.

3) Tuck your knees towards your chest, untill thighs and abs form a right angle, then thrust up to start position. This is one rep. Do three sets of 15 w/ 3 minutes rest between.

Hope you enjoy and find this to be an effective upper and lower ab move!
