Hi, my name is Teo and I'm from Romania.ill tell you guys something quickly about me, I'm 20 years old, 176 cm tall and I have 151lbs and 14,5% body fat.I started working out 6 months ago and got some gains on my arms and back, a Little bit on chest and shoulders(only talking about upper body).Still I got imbalances like my left biceps is smaller and weaker than my right biceps and one of my lateral deltoid is smaller than the other.Is hard for me to build my chest but I got more mind muscle connection, by that i mean is more easy to contract my chest but is hard to fell my chest working when performing exercises..even my shoulders are hard to feel them properly when performing exercises for them, the most harder for me is the rear delt to feel it.I do have some internal rotation but I'm working on that.I need help to build my chest, the most important rear delts and fixing muscle imbalances..for me is a shame to have such a small chest.I hope I dont mind anyone with my long post but I really need help.Thank you
