Are personal trainers helpful or just a money making con?

The world of fitness often gets a bad reputation. It started with the expensive gym memberships, where we were seduced by shiny surfaces and trendy cafe spaces, and then once we paid our fees we discovered that we just didn’t feel like turning up every week. Then it moved on to personal trainers with boot-camp army-style tactics, who wanted to ‘push’ us but didn’t seem to have the empathy to realise that we’d used the majority of our willpower just to turn up for the session.
