My left knee feels no worse than it did before the bike ride.    We had a
"cold front" move in today (temps still in the upper 70's) but the humidity
and rain made my knee hurt more than it did yesterday.

I took the anti-inflamatory meds after the workout, but didn't go thru the
trouble of icing.    And when it was all said and done, i actually spent 2
hrs on the bike.    Nice easy pace of about 11 - 12mph at level 1
resistence, then for the last 15 mins I did a interval setting that went
between level 1 for a couple mins, then up to level 7 for a couple mins then
back to 1 and cycled thru.  That made me work up a very minor sweat, but not
enough to even make my shirt wet.

www.caloriesperhours.com   one of the most common websites we quote for
calories burned and calories consumed.

Also, my bike allows to put in height, weight and age.

Oh, I don't trust them as "true" numbers.    But to have such a difference
300 cals...  that's just nuts.   It'd be one thing to see a difference in 50
cals or so.  But another to see a 300 cal difference.

While on vacation I had access to the ellipticals.  I'd spend 15 mins
warming up on the bike, then go to the elliptical.   I could do about
45 - 1hr on that thing.   But I got a much better workout.

on the bike, because of my knee right now, I was just going at a slow,
easy pace.  It was like sitting and just moving my feet for an hour.
Its NOTHING like spending even 8 mins on an elliptical.   :-)

You are doing good at 25 mins.   Don't count yourself short on that.

I watch my soap on tape while on the treadmill.  I don't really have a
*rule* but the other day while contemplating skipping the TM, my only
thought was "But when will I watch Y&R?" (Like there aren't 2 other vcr's
in the house?)

Exercise - it's a habit like brushing your teeth.
