This may not look like the picture, but you can figure it out for yourself.
Start from a push up position with your legs spread.
[1]Lift your RIGHT arm, and move your LEFT leg through so it's in front of your RIGHT leg.
[2]Move your right leg so that your right foot is behind the left foot (your legs will be crossed left over right).
[3]Move your left foot in a small arc so your legs are uncrossed. At the same time switch your hands (pick the left one up and put the right one down).
[4]Extend your right leg and sweep it around (wide) in a counter-clockwise arc so that your left foot ends up covered by your right knee joint and your right foot is almost touching your butt (NOTE: steps 3 and 4 should be down in quick succession).
[5]Put your left hand back down on the ground, and move your left leg back to where it was in the push up position.
[6]Move your right leg back to where it was in the push up position, and you find yourself back at the beginning. Now, go back to step one and repeat.
