What's the difference?
I realize that there is a difference in heart rate for both, but what is better?
My target heart rate (being 22, 139 lbs, and for 20 minutes) is 158. If I choose random at level 2 on the elipitcal, my heart rate goes as high as 180. Is that bad? I realize the HR monitor might not be very accurate, but if it starts at 120-140, then obviously my HR is going up fairly high.
Also, is there a major difference between the stair climber, elipitcal, and bike? I get tired so quickly on the eliptical and stair climber, but feel like I could sit on the bike for an hour and not tire as quickly.
Is it better to stick at one level on the eliptical? Is it better to go to a higher level and only do it a short period of time? My biggest fear as I go through the weight loss is that I'll have to do more and more cardio to keep my weight down. I can't see myself on the eliptical for *gasp* an hour!
