are one of the best abs exercises you can do, and you can challenge your body in a whole new way with this same move by simply taking it off the ground.
To do it: Start standing with your feet together, hands clasped behind your head, elbows out to the sides. Shift your weight to your left leg, bend your right knee, and draw it up as high as you can to your chest as you turn your ribcage in toward your raised knee, drawing your left elbow to the outside of your right knee.
Slowly lower your leg back down and then repeat again on the same side. Do 15 reps with the right leg up, and then switch to the left.
Options: If it's too hard to balance right away, practice these with your right hand against a wall to start.
Give your workout a makeover to get better results faster.
