How long should one do a diet designed to put on mass for it to be effective and worthwhile?
Im 6', weigh 190 and I'm a fairly skinny guy but have been training for years so I have some muscle (sorry to be imprecise on BF). I am planning on 3 or 4 weeks of 6 meals, ~275 g protein and 4000+ cals, starting 3 days ago. i chose this period because i have tried to gain weight in the past to no avail, but for reasons i now understand, and I thought 3 or 4 weeks would be a reasonable period to adopt such a demanding eating routine. It does seem to be getting easier though, and I might extend the time table if it would be beneficial.
Beginning today with legs, I am doing some 10x3 GVT variation i found here (no time to pul up the article now, ive got class) with a Legs, Chest/Back, and Shoulder/Abs day each week. I am dying for some shoulder development and liked what I read about Gvt so this seemed to be a good choice.
So, how long should I be doing this? Routine/diet suggestions are also welcome.
this is my first post, so if the info seems excessive its to avoid not giving enough info. Thanks!
