What is Gymnastics Strength Training?

GST stands for Gymnastic Strength Training and is a method of physical conditioning utilizing gymnastics exercises. It covers all aspects of physical fitness and is capable of producing immense strength with no compromise on flexibility or joint range of motion, hereby differing from traditional weight-based strength training. Progressions are scaled back for adults, starting from complete beginner and leading right up to the most advanced gymnastics strength and flexibility feats.

World Class Training

Our GST classes are designed by Coach Christopher Sommer, long-time U.S. Junior National Coach who has over 30 years experience of coaching elite national & Olympic-level athletes. The same method of structured, progressive exercise has been used to successfully produce many elite level gymnasts and is now being taken up by many fitness enthusiasts around the world. We are proud to be amongst the first globally to share and spread this amazing approach to fitness.


GST produces steady gains in both strength and mobility. Here we use the word mobility to describe having strength throughout the entire joint range of motion. By encouraging strength throughout a greater range of motion, the joints open up, restoring lost movements and actually begin to strengthen as well. Better posture is also a side effect as the core is strengthened and weakness and tight areas are addressed, so that the body gradually moves towards balance.
