I have finally started to use my treadmill. My goal is to be able to jog, so I started by doing a walk/jog interval. I briskly walk (3.5mph) for 3 minutes and then jog (5mph) for 1.5 minutes. I do this 5 times a week and I am just starting on my second week. Has anyone had experience with this? I was just wondering how long would it take to be able to jog much longer than 1.5 minutes. Thanks.
That is how I started out, but I did it outside on the sidewalk and path near our house. I was surprised at first how little I could jog without being out of breath and not being able to jog further and having to walk again. I did about the same as you 3 minutes walk, 1 to 1.5 minutes jog.
Now, 3 months later, I am able to jog for more than 30 minutes without needing to stop. It took awhile, but I just kept pushing and made myself go longer and longer each week. You can do it, just keep it up. The body adapts quite nicely.
A little tip that helped me: Jog outside. You will keep going if you see other people out there. I kind of felt if they saw me stop jogging and walk, it would be embarrassing, so I kept jogging, LOL. That helped somewhat.
