DS has always been quite self-consious as is tall and skinny.
He recently started hanging out with friends who all work out a lot, and there is a lot of talk about body shape/ muscles/ protein etc.
He tends to believe too much of the advertising hype around e.g. protein shakes etc and rubbish his friends spout.
I'd like to help him by directing him to more reliable sources for realistic gym programmes and eating plans for a lad of his age.
Any advice?
