The Fitter Over 50 Remote Trainer is a training mentor. It is quite possible that you won’t meet, but the trainer will use the phone and email to run through a similar process to an on-site trainer, in order to understand your objectives, timings, locations, available kit etc.
You will still run through a health questionnaire, a discussion about objectives, likes/dislikes and a variety of other relevant points.
So, hopefully you like the idea of training with a professional, who shares age, experience, outlook, and some of the same pains as you. What now?
