Just suggested to an overweight friend that he ask his GP to refer him for ‘ exercise on Prescription ‘ which is funded in the UK by a lot of health trusts. I downloaded the referral form for him off the internet. His GP signed the form for him and the following day he had an appointment!
In Norfolk where he lives you are offered 12 weeks course of some kind of exercise to suit your needs, with assessment, monitoring and support
Sure lots of people doing the BDS would be eligible, just search ‘exercise on prescription’ plus your county / city.
