Since i started working with Jack, my back injury that i suffered 2 years ago, is no longer limiting me in sports and day-to-day life. In these 4 weeks i added lots of weight to my deadlifts, my vertical jumps has increased, my endurance has gotten a lot better and i fully returned back to boxing again. Thanks to Jack, i’m finally confident with my back. Feel like i’m 100% back in the game. Jack is a great coach with lots of knowledge and experience. Really easy to connect with through the app, great feedback and fast responses. I highly recommend Jack, he is a great coach.
