I just joined the gym and I've been using the treadmill for my exercise the past few days. I was just wondering what do you guys do when you are on the treadmill. The first time I put manual and kept the incline at 1.5 and I did about 2.5 miles an hour for the warm up (five minutes) and then 3.3 - 3.5 miles an hour for about 20 minutes and then cooled down for 5 minutes on 2.5 and then did my stretches. I kept checking my heart rate to make sure it was at a good pace.
This time I select Fat Burning (as opposed to Cardio) and the treadmill kept constantly asking for my heart rate and moving the incline up and down. I didn't feel to comfortable with it going up and down on me all the time. The speed didn't change though. I had to change that myself.
What should I be doing? Cardio or Fat burning routine? Or should I just select Manual and adjust it myself? What about the incline? Can someone elaborate on that please? I do feel my leg muscles differently with the incline.
Last question is about the heart rate. When I grip the bars for my heart rate I find that it is very inconsistent. For example I gripped the bar and it said 144 during my warm up. Absurd. I held it again (didn't change my speed or anything) and it went down to like 100. I find that each time I'm checking my heart rate it is very inconsistent. I have to check like three or four times before I get anything that looks normal. I can put my hand on the rails and it will go 144, 120, 140, 100, 130. Any thoughts? Am I doing it wrong? How long should I hold my hands on the rail before I pay attention to the reading?
