Chest, Bis (after hitting chest it will be hard to give your tris a good workout as your tris are secondary (assisting) muscles for chest along with frontal delts and will be exhausted from chest workout)
Shoulders, tris (give a day inbetween chest and shoulders as frontal delts are hit hard with chest and you want to be fresh to grow those grapefruit delts)
You can either take two days off and start over or you can do an extra day of bis and tris the day after back and calves. Forearms are important. Dont leave them out.
Im sure there are a lot of variations on this but keep in mind that UNLESS you are using chemical enhancement (u know who you are...ahem) you should really give a muscle some rest before hitting it if you are using it as a secondary assisting muscle (i.e.-frontal delts helping your chest workout, triceps get hit hard also in your chest workout). If you try and do shoulders with chest or the day after chest it will not be as productive or as strong a workout as if you put a day inbetween because they are still exhausted from working as secondary (assisting) muscles. (After awhile you will be able to remove these secondary muscles a little more with hand placement, contracting, locking out and not locking out, etc but that takes awhile to go by feel). Have fun.
