I also know that as a runner all I want to do is run. I don’t want to stay at home doing sit ups and trying to reach my toes!” – Carla Molinaro “SCY is a total game changer. I have tried to incorporate strength conditioning and yoga into my training for years, but just found it so boring that I never managed to do more than a couple of weeks, before giving up. But these videos are so stimulating, short enough to easily fit in, designed for all types of athletes, with adjustments that can be made if wanted. The exercises are so unique and dynamic. I love Carla's enthusiasm, and that it’s ok to struggle to get into some of the poses which other yoga teachers do effortlessly. I love that it's especially designed to make me run better, and injury free” - Karen, SCY member "It’s a small commitment with massive reward.
