Question about changing splits

[killamac27]

So I would normally do legs today but they are still sore, and I just lifted with my shoulder and back, and biceps yesterday and i'm not sore at all besides a little in my lower back, would it be okay to lift with my arms again today? or should I always give a day rest?

Look up a proper training split and keep to it, to not plan is to plan to fail
