I have worked out 3x a week for mostly over 90 minutes, I did 9 weeks through now and I must say...Due to split for the last 3 weeks I am constantly sore somewhere, I skipped 2 out of the 4 days running cause I just didn't have the energy anymore the last 2 weeks. So I think it is time to take a break to replenish some energy, I just don't feel I am doing my best since I am overall a bit exhausted. I checked out some programs, and I was surprised in most of them are a week long breaks. Is a week not pretty long ? Do you still go running and just don't lift ? On a side note I SO badly just want to sleep for 20 hours straight through,i can't even hear the alarm clock anymore. I usually only get 7h a day. Do you sleep more if you work out to your max ? It is just not always possible with having a demanding job.
Maybe you're not eating enough? I don't know. I work out 3x a week for maybe 45 - 60mins. I don't do a lot of running/cardio because I'm already pretty slim. But it does seem like you're running yourself ragged. Seven hours sleep is more than a lot of people get (I'm shy of that, but would like to get more.). I'd suggest scaling your routines back a bit.
As for a break, keep it as short as possible. A week should be fine.
A good rule of thumb is 4-6 weeks on, 1 week off. You'll get varying answers on what constitutes "rest." Some will say that doing nothing at all for a week is what to do. Others continue doing some form of cardio. It's usually difficult for hard core worker-outers (i know, not a real term) to do absolutely nothing for a whole week.
It's really something that you just have to play around with and see what suits you--as with everything to do with working out.
