I was a total wreck today. Had a very long and tiring day yesterday and didn't have any energy what so ever. Due to this I skipped my chest and triceps day (following the 5 day bodybuilding split program). I'll probably go to the gym again tomorrow, but I'm not sure what to do. Should I start my week routine tomorrow (so do chest and triceps tomorrow, back and biceps wednesday etc.)? Or should I just skip chest and triceps this week and follow my routine like how it's planned (back and biceps tomorrow...)?
