just curious to hear a few of yours routine on the treadmill.. i was planning on doing stairmaster, but then i realized that the machine i thought was a stairmaster was some kind of cross country crap machine... so anyways.. i was wondering how you guys do it.. do you do like 5mph at an incline of 5?? or 8mph at 0 for 2 min then 5mph for 2 min or what?? just trying to get some ideas for my PWO run/jog/walk.. starting at 20 min intend to get up to 30-40 eventually.
