Weekly Routine Advice for Strength Building

[armweak]

Hello,
My goal in lifting is to build bulk and then work on muscle definition. I am in the bulk building phase and need some help in crafting the most effective plan to get big and strong in a manner conducive to healthy living (no injuries or long-term pain as a result).

My current routine looks like this:
M - shoulders and chest
T - biceps and triceps
W - rest
Th - rest
F - shoulders and chest
S - biceps and triceps
Su - rest, legs

Is it bad or stressful on my joints if I lift bi's and tri's the same day?

Thanks for the help!
Neil
