I only train arms once a week since any more stress on my arms would detract from other lift that use these muscle as stabilizers and secondary movers. Also, I really don't care about arm size since in fighting they slow you down, at least for me they do. It does not mean I can't lift heavy since I feel arms can benefit from heavy weight, but I feel they respond better to controlled speed lifts....
Two days a week maybe for some who can heal that much
