“I rely on core strength, balance, timing and an overall level of very specific conditioning and fitness that allows me to do the kind of stunts that I do in my trick shot show.

Jason Krantz has created Sonic Boom Golf, which will provide golfers of all ability levels the opportunity to use greater levels of fitness to improve their form and function and enjoy a better, longer lasting golf career. I would highly recommend the Sonic Boom Golf fitness programs to anyone interested in taking their golf game to the next level through a greater level of golf specific fitness”
