Rowing in leau of running
This is a big year for me with the Outlaw Half and my 1st Ironman (Wales). Problem is 2 weeks ago I sprained my ankle. I haven't been able to run but I can use the rower in the gym without to much of a problem.
Here's the crux though, my perceived exertion level during rowing is far higher than if I ran with the same heart rate. Do I need to alter my HR zones like I have for cycling (i.e. subtract 5%)? Or is rowing just harder anyway.
Has anyone used rowing to maintain or build their endurance while injured and was it effective?
