Howdy. I’d class myself as an ectomorph. Started at about 60kg(132lbs)(6’) with the skinny-fat look some people talk about at times on the forum and in T-Mag. 3 years later I’m still not HUGE, but definitely bigger. Now at 75kg(165lbs) and leaner. 10lbs a year aint bad, and my growth has been steady, primarily due to learning better techniques and principles as time goes by. My best growth phase was actually in my third year, when I started the SEE-food diet. I SEE food, and I eat it! Man, you’re gunna have to eat a f@ckin’ sh!t load of food to gain weight! I wish I’d properly realised that when I started… [shrug]
Like the other guys said, read T-Mag religiously, and follow the principles it teaches you. You CAN do it bud! Never think it’s impossible!
