Hello, i have been riding now for almost a year and my brother has recently decided to start riding with me. I have already built pretty good fitness by simply riding, and don't want to push him too hard especially now at the start. He is 1.9 m (6'2") and weighs around 120 kg (266 lbs). I really want him to continue riding with me, albeit at a slow pace to start, and i want to find a way to keep him motivated without crushing his body. His main goal is to lose weight (I think his main goal is around 90 kg) any suggestions as to a training regimen or diet plan would be greatly helpful. Thanks.
