Welcome to JKF Fitness & Health


Smart, Innovative, Funny, Entertaining, and always a little Irreverent


The focus stays on our clients as they achieve the bodies they want.


And We’re back!

Well, at least in this mode.

The past two and a half years have been quite the journey for myself and JKF Fitness & Health. With many thanks to my faithful and persistent clients who have stuck with me and/or joined up during covid, it’s because of them and you that the business and thus our services carry on.

I would like to think the company is stronger - with in-person training fully back on and a robust and more fully developed portfolio of virtual training available. It’s now easier and more efficient to start and keep up with your workout routines with JKF Fitness & Health.

So thank you for being on this journey with me and cheers to what comes next.

People are Talking . . . 

Read in the words of current and past clients why they love John and JKF Fitness & Health

If you want to use every ounce of energy and feel the most alive you ever have, John is you trainer. I started with a low level of fitness and over a year and a half, have been replacing pounds of body fat with muscle month after month and feeling better in every way. John is extremely knowledgeable about body composition, exercise and nutrition and puts together a plan that fits the goals you want, be it strength, speed or if you just want to look like him ;) Everything is tracked so you can see your progress which helps when it gets tough. It does take time but you have to trust the process, it works. He will push you to your best, you'll grow muscles you never knew you had but theres always fun and good laugh to be had. It doesn't get easier, you just get faster stronger and lift heavier. Flexibility is great, whether its your local gym or home gym (my preference) and if the session starts late, you'll go until your finished. If you are looking for a personal trainer that actual cares about your health/wellness/fitness, John is all that, and more.

Healthy Recipes

After talking endlessly about my tasty black bean dish to client Eli, he finally demanded I send him the recipe. Then he sent me evidence of him adding it to his diet. Couldn’t be a prouder #trainer.

Master the Squat

Checkout the ultimate squat progression

Squats are one of my favorite exercises and one that I try to make sure all of my clients (no matter age or ability) master.


As I tell them, if standing up is something you're going to be doing for the rest of your life, then squatting is going to need to be a part of your exercise routine.
