What are the best forms of cross-training during marathon training?
Sometimes I like to take a break from running if my joints need some rest. One thing I’ve noticed though is that I can’t seem to get my heart rate into the same zones compared to running.
On the elliptical I’m usually only around 108 bpm at like 75rpm and on the indoor bike I’m sometimes even lower around 98 bpm. Incline walking is the only thing that gets my HR somewhat closer, but I have to do like 15% incline at 3 mph just to get around 120 bpm. Swimming is great but I don't have access to a pool at like 5am to 6am.
Whenever I try to push more to get my HR up, my muscles fatigue faster, my effort is really high but HR low, which is the opposite of when I run.
Anyone have any tips?
