In the week I often have a sleep-deficit and some stress. Would it make sense to concentrate on resistance training in the week-end and cardio in the week?
I understand these conditions are best for resistance training, but perhaps the same is the case for cardio?
For me the important thing is balance between results and side effects (such as DOMS). Performance is not important. (If you train hard, and want max results pr session, things are probably a bit different)
Cardio sessions might not be so different, but they are less eccentric.
