I’ve always struggled with my weight. I underwent a 4 month physical transformation with amazing @ewiswelshfitness.

“The left is me at 98kg, the right is me now at 73kg I lost 4 stone and I’m in the best shape of my life at 41 years old.

Was it easy? never. So many sacrifices with my loved ones and it’s been hard work but it’s one hell of a ride I’m proud of and it hit me in the gym.

Anyone can do it if you put your mind to it and be persistent. Many thanks to ewiswelshfitness. My fitness journey is complete.
