I am trying to get my arms bigger in size. I have been training for about a year with some results. I don't go to a gym I work out at home with free weights. I dont have a bench. What are some suggestions from you guys on what exercises to do including # of sets and reps, and how many times to work my arms a week. Right now I work my arms 3 times a week and the exercises i do are done to 5 sets for each exercise and 8-10 reps.
