I need some advice from bodybuilders with 18+ arms. Currently my arms are 17.5 inches and would like to get them to 18 inches. I can curl 120 pounds for reps with good form:no back leaning or using legs.
For triceps I use tricep pulldowns using the whole stack for 20+reps. What are some things I can try to get my arms larger. Should I shoot for 135 pounds in the curl with good form and what are some tips for the triceps.
I must note that I cannot do tricep extensions because they put too much stess on the elbows. Also, what is a good arm size for a natural bodybuilder?
