Hello and welcome! I’m Gav O’Brien and I’m a personal trainer based in Brighton and Hove in East Sussex. I am the author of How 2 Get Fit 4 Later Life, the must read exercise and nutrition guide for people aged 60 and above.

I offer a fully mobile personal training service right across Brighton and Hove and the surrounding area at your home, office, outdoors or in a private studio. My mobile personal training service perfectly fits in with your busy work schedule and is also ideal for clients who find a gym environment uninspiring, unfriendly or intimidating.

I firmly believe that age is but a number and I continue to develop my skills as an older adult personal trainer. So, if you live in or around Brighton and Hove, let me be the personal trainer who helps you achieve your fitness goal the 3Fs way - getting you back to being fighting fit forever!
