Still bike periodically, but with the heat my biking gets more sporadic. I'm concentrating on P90X right now. Here's the link: http://www.beachbody.com/product/fitness_programs/p90x.do.
It's a great workout and so much fun to do from the comfort of your own home (in air conditioning). :) Super excellent for toning. OOOh yeah.
I'll get back to biking in the fall, once things cool down a bit.
As a side note: I've lost a total of 20 lbs this spring/summer due to healthy eating and bicycling.
Thanks and roll on. ;) Later.
