I've been doing about an hour on a spin bike 5 days a week (and then jogging for the 6th, 7th I take off) for about a month and a half now, but just this past week both of my achilles have started bothering me. They only hurt a little bit, but they feel tense and I occassionally get a "zing" feeling. They feel very "precarious" so I'm taking a break.
I've read that pedaling too much on your toes can cause this (see here http://www.caree.org/bike101bikefit.htm ) and I've made the necessary adjustments for that. I will try spinning again in about a week, but I was wondering if anyone else has any other suggestions.
Other things to note: I'm using a Sunny Health and Fitness SF-B904 spin bike (quite cheap, but the only magnetic spin bike I could find in my price range). The highest resistance level isn't much to speak of so I quickly found myself needing to constantly sprint (not sure if this could increase the chances of injury). I plan to add more resistance by adding extra magnets. The bike is quite small--it just barely fits me at my height of 6'2", but I'm still well under the weight limit.
