People vary in their ability to recover as much as they do in everything else. Jim Williams, who was the first man credited with a 700 BP, allegedly trained his bench press every day. The Bulgarian Olympic lifters train up to five times a day.
You can go on a split routine, if you absolutely can’t stand not training. That would be something like chest, shoulders, and triceps on Monday, back and biceps on Tuesday, legs on Wednesday, start over on Thursday. That’s fairly advanced training, and I don’t get the feeling you have advanced that far.
If you want to try a split, do chest, shoulders and triceps on Monday, back, biceps and legs on Tuesday, rest Wednesday, and then repeat the cycle Thursday and Friday (or Saturday). That’s a more basic split. You can also lift on MWF and do aerobics on TRS.
Or even a three and one rotating split. There you train three days in a row, take a rest day at the end of each cycle, and always take Sundays off. Thus Monday you do chest/shoulders/triceps, Tuesday back and biceps, Wednesday legs, Thursday rest, Friday chest/shoulders/triceps, Saturday back and biceps, rest Sunday, Monday legs, rest Tuesday, Wednesday chest/shoulders/triceps, Thursday back and biceps, Friday legs, rest Saturday and Sunday.
On the other hand, I am of the old Peary Rader Iron Man magazine school that says that if you have the itch to train more often, just train your current sessions harder. Not longer, harder - cut your rest periods between sets down, add another ten pounds to the bar, shoot for every rep on every set to be absolutely perfect, that kind of thing.
