If your forearms and wrists are hurting, have ou ever considered using straps?
I have got bad wrists from years of skating, and I find using straps helps so much! They are dead cheap, here is an example: <a href="http://www.amazon.co.uk/dp/B004K1WMYM/ref=asc_df_B004K1WMYM10487449?smid=A3R93BZTZIK0F7&tag=hydra0b-21&linkCode=asn&creative=22242&creativeASIN=B004K1WMYM&hvpos=1o5&hvexid=&hvnetw=g&hvrand=2216177101169137680&hvpone=&hvptwo=&hvqmt=">straps</a>
I find these especially useful when doing shrugs, deadlifts etc..
Also, recently switched pre workout supplement to Muscletech Neurocore. Not usually a fan of Muscletech products but after reading good reviews I thought I'd give it a chance: Feeling pretty positive about it so far, really good 'pumps' (hate this phrase) and good concentration.
