So, I am normally a bicycle commuter. Also, I am normally late, so I sprint through company property (occasionally being chastised) to get into position on time.
Sadly, I have been diagnosed with tendinitis (I imagine from the treadmill.) Therefore, I've been told I should try not to run or bike for two weeks!
Therefore, my question is: what can I do to maintain cardio? My access to a lap pool is limited, but it exists.
Edit: Looking, basically, for what cardio I can do that does NOT involve my lower legs supporting much weight or taking a beating. The nature of the restrictions are to rest my left Achilles, if possible.
