I notice that when I'm running, I can easily get my HR up to over 80% by taking longer and faster strides - H.I.I.T. Run hard, rest, run hard, rest, etc. I breathe a lot harder and feel like I had a great workout. However, when I'm cycling, I can't seem to / don't know how to push myself harder to get the same effect as a running. So I was thinking of getting a HRM to try to get the same intensity from cycling as from running.
Any recommendations on some of the top-of-the-life HRMs for running that can also be used for bicycling and possibly swimming? I'd like to import the data into an Excel spreadsheet after my workout to plot charts, etc.
Also, how does a HRM work? Is there a wireless connection between the device and whatever is attached to my body? And what is attached to my body, a band around the chest? How does it stay in place and not fall when running, swimming, and cycling?
