My name is Chip Kelley, and I help guys who think think their mid-30s or later is past their prime with building a stronger and more athletic body. It is never too late to get back in shape. I am a competitive bodybuilder who did his first show in his 40s...and I still compete and win against guys half my age. I have been a personal trainer and gym owner, and I am now focusing on on-line training. If you are ready to commit, we will set up a consultation and look at program options that works for you, your goals, and your lifestyle. * App access requires paid coaching plan Terms of use: https://kahunas.io/terms-conditions Privacy policy: https://kahunas.io/privacy
