Hey, it's great that you are checking out different classes and the such. There truly is something for everyone, you just have to look and keep an open mind.
I just stopped my gym membership... i stopped attending classes, they just weren't for me... I prefer doing yoga alone in my living room with my TV.... and I finally purchased a barbell to add to my little "home gym" corner in the spare room. I just haven't gone to the gym in about a year now, and I have still kept up my exercise, and I can still make my abs and glutes burn from home. But, I have spent over 2yrs learning what worked for me and I tried everything more than 2xs over before I figured it out.
