Exactly four months ago, I firmly started to go to gym lifting weights 6 days a week and I've been able to do that at 90% success. But I'm not happy with results. I wanted to build some muscle and put a bit of 'healthy' weight as I'm a bit slim. I eat well and healthy and yet no difference. It seems I never excercised.
One problem maybe that as my doc told me I have a fast metabolism which doesn't allow me to build muscle. But I could be wrong on that. I'm acutally a bit disappointed and need some advice
