Bis and Tris?

[yellowcard6006]

Do Bis and Tris take longer to grow than your other muscles?

[imperfectly_lou]

They are smaller muscle groups so usually, yes.... but it really depends on genetics. Some people can grow bis like crazy and struggle with their legs..

also depends how you hit them, i've invested alot of time and reading into arms training. it's too long to type out, pm me if you'd like more info

I think they do take longer to grow, that is seems for me to be much easier to add an inch to chest or back or other major muscle groups, than it is to add an inch to your arms. But proportionately, I'd say about the same to grow if you train all bodyparts equally, that is besides genetics.

same.. chest and back seem to grow alot more mass faster.. but then again they are much bigger muscles..
