If you are a neophyte at Yoga or a seasoned practitioner, Greenhouse Yoga is the place to go. I am a middle aged guy who has very tightly wound muscles and is not very flexible. I road bike, play squash and snowboard but always feel sore the day after. My wife got me into yoga over the summer but I went infrequently. Recently, I threw my lower back out and could not do any sports for nearly a month. In that time, I went to Greenhouse Yoga almost 5 days per week. Under the tutelage of Alex and at times Patrick, I gained more flexibility and range of motion. As it turns out, many of the movements and stretches work on the lower back (along with your hamstrings,calves quads, hip flexors arms and trunk) while also building up your core. I am not naturally flexible and my body cannot do some of the poses and stretches. But at Greenhouse nobody judges you or tries to push you to do something you are not comfortable doing. After time, I noticed I naturally pushed myself as I got more familiar with the various poses and movements. All the teachers have a very gentle, soothing yet inspiring style that really engages everyone in the class. The studio is clean, well lit and calming. My only regret is that I did not discover Yoga earlier in my life! if you want a great cross training activity that really prepares your mind and body for most any athletic endeavor, I strongly recommend taking a Yoga class at Greenhouse Yoga. You will not be disappointed!
