New Yoga Lover?

Yes I think I am. I have never really participated in a good yoga class before. There was one I went to once awhile back with mostly older people and it was slow and boring. This new yoga class I went to last night was a mixture of all ages and it wasn't as easy as it looks. In the beginning and the end there is alot of stretching which feels really good but in the middle there is alot of core strengthening through poses and other exercises. I actually was sweating and breathing heavy in the middle section of the class. It was an hour long class that I took last night at my gym. Today I'm feelin pretty good. I never thought I would say this but I think I love yoga and will definitely be going next week.
