Battle Rope ST has been my introduction to what a quality workout is. As a cardio fanatic for many years, I didn't know how important strength training was to looking and feeling truly fit. Battle Rope ST is the perfect combination of cardio and strength training and has defined muscles I didn't know I had! Even though it is a very high-intensity workout, I never feel that my body is absorbing shock and stress- the fluid movements w/ the ropes build muscle and endurance in a healthy way while toning ALL of the muscle groups. It is, by far, the most fun and rewarding fitness training I have done. Thank you, Battle Rope ST!
