There are many things you can do for legs but not much of them are "on" the pole.
Moves like the side climb, star, crucifix, caterpillar performance climb are all great for the lower body. Working on conditioning moves is a good idea, these will not only strengthen the lower body but also help you improve your lines. In the lessons some examples are Pole leg lifts, sexy squat, booty lift.
If you are using the lessons and ever wonder what muscle groups are being used take a look at the description below each lesson and you'll see I have listed all of the muscle groups used. You'll also find a group of "related lessons" under the main player that will help build the strength or flexibility needed for that move. https://www.studioveena.com/img/smilies/icon_flower.gif
