we all want big ass wings man, you need to learn how to train your back correctly befor you take synthol in them....
95% of people in the gym have no idea how to train their back(i will put money on this) first you need to learn how to pull with your elbows and not your hands, think of your hands being hooked to the bar, and concentrate on pulling your elbows down or back....
maybe your insertions are high, if this is the case you will always have a hard time with your back...
all these synthol threads are getting a little out of control imo,
if you want an honest opinion post a few pics of your back, this will tell a lot ....
