As a personal trainer, i've dealt with many clients experiencing muscle sore & aches all over their body as a result fo bas posture & desk-bound for prolonged period of time. With YŪGUN, it helped me to reserve my energy to train my clients better. It targets trigger point which release more effectively at different parts of the body, which comes together with its exchangeable 6 heads. I love the 6-speed percussion, it gives more variability for my clients with different tolerance level towards the trigger point experience compared to other massage gun in the market. YŪGUN's design definitely looks lit & its functionality is top notch, like the cool factor you're using an iPhone to other phone brands!
