What I don't get about this comment, and many others, is why do you have to choose one type or the other. I believe a varied exercise plan will be more helpful than just focusing on a single exercise type.

Run one day, lift for upper body the next day, HIIT the third day, abs and light cardio the fourth day, lower body lift the fifth, rest day and go for a bike ride on Sunday.

Sites like fitnessblender.com can help you get there. (I've been mentioning them in these threads because I love them, the changes in my body and most importantly, in what can I do with my body have been nothing short of amazing in a relatively short amount of time)

The Starting Strength book recommends that to maximize your strength gains, on your rest days, you really do /rest/. This facilitates recovery, and muscle growth and strength increase happen when resting, rather than when exercising.

I occasionally run/cycle/hike/shovel snow/etc. as well, but working for the three weight lifting workouts per week. I'm not faithfully "doing the program", but incorporating elements that work for me into my life.

There's probably a comma missing in my sentence, I meant, if starting the routine on Monday, rest day on Saturday and in Sunday go for a ride.

I agree rest days should be rest days. I've paid the price of not resting a couple of times too many already.
