hello--- i work out on the treadmill for about 45 min/day... i vary the incline and speed , (only run for about 3 min after 10 min.)..will cardio coach help me--- i listened to a clip and it seemed as if he just encourages you.... when he says to bump it up--- are you using heart rate to tell you how fast or slow to go? what is the true benefit of it? also, do most of you buy several cd's at 20 dollars?, (i know there are sales) or do you just replay one over and over? if i just want to buy one, which would you recommend???
