Well, I can tell you no matter what your size or workout routine, inversions are tough. I finally got upside down for one of them then slid down the pole and thought I broke my shoulder! I guess they are serious when they say don't try those without a spotter!
The great thing about the removable poles is that you can slide your cocktail table out of the way and put it up in the living room or even in the kitchen, then take it down when you are done with it.
The lessons are a good idea - it's so different when you have someone show you in person as opposed to the videos. If you can go to a strip club it's always a fun night out, especially if you are bi or at least can enjoy watching pretty women dance, but be sure to go to one that is either couples or woman friendly. Also some are seedy and the dancers just aren't that good - but there are some really nice clubs with classy dancers in some areas.
