This move can be do with 3 pound hand weights for a more advanced abdominal workout.
Lie on the floor, stretched out. At the same time lift both legs and upper body up into a V-position with arms reaching up on an angle, shoulders down and chest lifted. Slowly return back to out stretched positon. Repeat 8x
Next come up in same V-sit but twist to the right then return back down. Come up in same V-sit but twist to the left then return back down. Repeat 8x
Next come up in same V-sit, but bring right leg up only then return back down. Come up in same V-sit, but bring left leg up only. Repeat 8x
Next come up in same V-sit, but bring right leg up, then left leg up, then return back down. Repeat 8x
Finally come up in same V-sit, but weighted hands are use to brace you as you lift both legs up and hold for 5 seconds then return back down. Repeat 8x.
In my class we repeat each sequence 8x then 6x then 4x. This helps us learn the move while getting a great abodominal workout.
