Finding a decent trainer can be tricky, so many you see in the world of social media may "look" the part, but don't have the in depth knowledge and years of experience I personally would want from a PT. This is however what you get from Simon "Diesel" Yates. As an elite level strongman and former champion bodybuilder he uses this wealth of experience to train anyone of any age, at whatever level and most importantly to whatever their goals may be.
I don't recommend personal trainers often. I would certainly recommend "Diesel"
