For quite some time I've done the 4-day and 5-day splits which have worked quite well but I think I've been over-training as a result.
I've changed to an 8-day split so I'm training the same body part every 8 days:
Sun - rest
Mon - chest (for example)
Tue - train
Wed - train
Thu - rest
Fri - train
Sat - train
Sun - train
Mon - rest
Tue - chest (repeat after 8 days)
I've found that I'm gradually getting my energy and enthusiasm back and it's working pretty well for me. I'm more endomorph than mesomorph (60%/40% endo I'd say) by the way.
What do the group think about the split? Is this too much recovery time? Is it acceptable to making good gains or good for cutting up? Or is it a waste of time?
