Freestyle sports are dynamic and exciting, gaining popularity within the UK for providing participants with the ability to express themselves creatively through movement and an incredible range of tricks. To help capture the power and explosive nature of freestyle, British Gymnastics has developed a new club-based activity called FreeG, which comes indoors and introduces a range of freestyle-specific training techniques to take your trick learning, to a new level.
