Not that a ten minute spin yesterday was a major undertaking, but so far today, I have no heel pain. I also did a 5 minute warmup on the Airdyne before my weights workout today, so it seems like my heel can handle small amounts of cardio work at this point. Hey, I'll take what I can get.
Speaking of weights, today's workout took me to a place I hadn't been to in many years — to the edge of puking and passing out. I downed a cup of strong coffee just before the workout (which I've done before), then hit it HARD. I not only increased the intensity on every lift, I also added sets and ended up extending the total workout time to 68 minutes. Too long, based on most knowledgeable opinions. I was training on nerve, starting to get shaky, getting tunnel vision and feeling pretty queasy. I've been hitting my entire body in each workout, but from here on out, I'll be splitting up body parts in order to keep the workouts short(er) and intense, without the overwhelming desire to drive a porcelain bus.
I hope to do another stint on the Airdyne over the weekend — probably only 10 minutes again, just to play it safe.
