Hello all Iam 18 and have been lifting for about 4 years. My arms have never really been that big and Iam trying to change that. I have been doing a ton of arm stuff latly and I cant even feel it in my bies and tris after lifting. It is really anoying. This is what I do for my arms. alternating dumbell curs 4x10 60 pound dumbells 4x15 50s and 3x35 30 pounds. Concentration curls 4x15 40 pounds and seated alternating curls 4x15 with 50s. This is all I can do at the moment cause my car is broke and I dont have transpertation to the gym now. What the hell is wrong with me that Iam not even getting sore. What can I do to increase my arm size? Iam looking to go naturally cause I dont have money for supplements. Thanks for the help.
