I don’t have the words to describe how good Jack’s work is. From planning my fight camp nutrition, conducting metabolic testing to assess my individual requirements, educating me about which supplements are safe to take & introducing me to other high class performance coaches. Jack has helped me reach new levels in my boxing career, I wish I had started working with him years ago.

Professional Boxer

I used to engage in weight making methods which included starving & dehydrating myself during a training camp. Jack has shown me how to make weight safely without sacrificing my health or performance levels. In my last camp I lost 4kg of fat & retained all my muscle mass. I have never felt as fit or strong in my whole boxing career.

Jack helped me manipulate my weight safely during my training camp, educated me about safe & supplement use & catered to my dietary requirements (gluten free). The changes I made to my nutrition resulted in huge improvements in my performances in training & in the ring. I’d strongly urge any combat sport athlete that’s serious about performing at their best to get Jack on board as part of their support team.



Working with Jack has completely opened my eyes about nutrition & changed the way I approach my diet in & out of fight camps. I now feel stronger & fitter during training sessions, my weight has come down & my muscle mass has increased which has led to my punches carry more snap & power. The level of detail Jack goes into is immense & I would recommend any fighters who are serious about performing at their best in & out of the ring to get in contact with him.
