I've been coming for over a year and I still really love it! You'd think that it would start to get boring after taking a hundred classes or so - but, nope! They keep adding new and interesting elements that keep it fun and challenging. I have noticed a marked difference in my strength and posture. Muscles are definitely tighter and firmer. (And, there is a HUGE sense of accomplishment when you finally successfully do pretzel!) This is a great workout. Try it . . .you'll like it!
