hey guys,
after 13 weeks of hard and strict training i´m taking some days off now, actually i´ve also got a light cold....but after that rest, i´m planning to train hard again and will try to gain some 20lbs in the next 15-16 weeks, until may.
therefore i´ve made up a wourkout routine and diet. what do you guys think of it ?
i´m 19, 6´4´´ and ~200lbs; natural; body fat: don´t know exactly, not ripped to shreds, but visible abs
