[cloud_strife]

hello, I am 30yo, 5ft 11in, 176 lbs and 13% bf

i have been training since 2003 ( starting from 112 lbs, I was very skinny) to 2006 but with some interruption because of university stress, then I am training regularly from 2007 with almost no interruption, except for one of 5 months from august 2010 to december 2010 (because of leg injury)

I have done a couple of mild cycles (mostly 300mg test and 200mg deca per week)and whilst I managed to add some mass to my very thin frame , but now I would like to increase the dosages to 400mg test and 300mg deca and look more massive, not just athletic

workout description

i am keeping the number of reps relatively high for now....

i currently train at home, so I left out one of my favourite excercises i.e. lat pulldowns.... but I am getting a lat machine in may

I do two different groups of workouts a and b, first week wo a, second week b, third week a again etc

I would like to currently focus on back and shoulders (my legs improve easily,so I am training them only once in two weeks to concentrate on my thinner upper body for now...and also because of recent injury(1 yr ago)
arms are almost ok and pecs are bigger that they should be compared to the back

the general rule is to train each muscle twice per week with around 12 sets for the big muscles and 8 sets for the small muscles; so a big muscle get 24 sets per week in total; i found that training each muscle twice per week works a lot better for me than only once per week
I wrote for each day the total number of sets per workout. I was usually doing 30 sets in total, but some gym fellows advised me to cut the volume so now I am doing only about 20 in total per wo day; i.e. except for the back where I kept near 30
