I think you'll have to decide for yourself if 6 days a week is too much - whatever works to keep you motivated
. I've been an on again/off again exerciser for 20 years. I always started up at three days a week, and I'd keep at it for anywhere from a couple of weeks to a few months. What happened to me was that I'd find (or make) excuses for that day to be an 'off' day, and eventually I'd get too many 'off days' to keep the habit. I've started up again as of a couple of weeks ago and I'm doing it everyday this time. This gives me no leeway to make excuses, and to tell you the truth, it does put me in a slightly different mental space to know that I can't put it off until 'tomorrow'. If it's part of the daily routine, like 'eat breakfast' and 'brush teeth' then you don't want to think about not having the time *today*.
I did start much more slowly than I have in the past though. With no days off for recovery, it is extremely important that I don't push myself too hard. I'm letting my body dictate the speed at which I increase my time and difficulty. The first few days I only did 10 minutes on the elliptical (very slow speed) and 10 minutes with weights. Now, two weeks later, I'm up to 35 minutes on the elliptical (reasonable speed), but I'm still at only 10 minutes of weights. My body doesn't want to go as fast with weights as with cardio.
After two weeks there's a huge difference in all kinds of things. I'm sleeping better, I'm not craving big bowls of pasta or pizza, and I've lost a couple more pounds. So - yes, you see results fast, even at a slow pace.
