I set a goal last year to gain 10 pounds. The one year anniversary is today and despite hitting the weights regularly, supplementing an average of about 30g of protein/day to my diet, all I have to show is a measly 4 pounds. Muscle definition has increased but not bulk. I don't wanna be a muscle monkey, no sir, I just wanna fill in a bit, improve muscle endurance and prevent overuse injuries . I dont want to give up on my cardio fitness so I cant stop biking. Besides biking is fun and keeps me semi-sane. The area where I can gain weight that will be useful should be in my long legs, but try as I might, its pretty tough to get any muscle mass on there. Anyway, I think I am at the point of reconciling myself at being 140#s and deal with it. While I have never been one to languish over my body, I find myself oddly wanting to gain weight for some reason. Being an ectomorph sucks as well .
