A friend had a similar mishap a few weeks ago -- dog collision, busted up her arm and elbow. She tried to do the Zwift thing for awhile but apparently it wasn't practical with her arm temporarily disabled. A road bike on a trainer still demands the same ergonomics -- not suitable for upper body injuries. Maybe a more upright spin bike, one of the older style types.
Good time to work on those legs. Squats, lunges, etc.
At least that's what I tell myself when my neck is aching too badly to ride. Like today. On the plus side I had some great rides with friends Friday and Saturday before the neck thing kicked in again.
It's been sunny and fairly warm today but the last thing I want to do is clean the mud off the Univega from Friday's rainy ride. Can hardly lift my right arm to do anything useful.
Sometimes the best thing to do is rest, or activities that don't aggravate the injury.
