I love the instructor for your Yin yoga class (Laurence). Only wish is that she teaches more classes after work hours and at more convenient central location. The class was small and intimate which was great. Laurence explained in great details and have good knowledge of body anatomy. I think even for beginners, the class was not intimidating as Laurence tries to help and give a lot of options. Laurence has a very soothing voice which really relaxes you. The mat (very sticky so I really like it) and props are all great. Only thing is I wish there was an option to use therapy balls (hard ones) instead of soft tennis balls.
