First Unitarian Church – 2125 Chestnut Street, Philadelphia, PA. We have decided to shift our focus to mat grappling in hopes to find others who are interested in wrestling and conditioning but may not have ambitions to compete. Our session will remain safe and controlled with some instruction but looking to have more fun and social element too. We welcome ideas from new and seasoned members alike. We are looking for members 18 years and up. We are open to all sizes and weight classes. Warm up with some aerobic and high intensity exercises Stretch with Yoga poses and pair up and work on assisted stretching Open the mats for some instruction and some fun ground grappling Suggested Gear: Wrestling Shoes or barefoot, wrestling singlets if you have or shorts and Tshirt.
