Not only is endless treadmill running boring, it's better to mix up the movement/impact. My current favorite routine is a 10-15 minute run, then 30-45 minutes of rowing (talk about boring, try being on an erg for a couple of hours). I also don't think its as effective to split it up to two workouts a day if you're doing under an hour, total. 20 minutes of cardio barely gets you going.
i usually mix it up every few days, but even with longer times unless i just run, i usually don't feel like i really worked out. but with mixed in with regular running, i run intervals, sometimes i do this simulated hill walk (my own, not the stupid treadmil profile). this morning i ran for 30 minutes and then did the hill walk for 15. it wasn't too bad, but by the end of the 30 minutes i'm so burned on running mentally. my condo's gym only has treadmills, elipticals, bikes. maybe i'll try running in combination with something else tomorrow. haha, but based on your times, i see it's a minimum of 40 minutes up to an hour? damn... (= hopefully the changing movements will help bc that's beyond my limits for interest in the gym, unless i'm lifting. edit 4/20/06 - been doing the hour this week (well monday i did 45 minutes). yesterday i did 30/15/15 (run/eliptical/bike) today i did 30/30 (run/elip). it definately helps to change movements to combat boredom. hopefully upping the time and changing movements will kickstart my ass into getting into better summer shape (haha, oh the vanity!)
