Exactly. She's the perfect messenger!

Well, it might make you feel awake and refreshed, but unless you're truly out of shape, a leisurely ride does not do all that much for one's fitness level. That's one trouble with cycling being just too damn efficient.

Firstly, fitness isn't as simplistic as "calories burned". It's about things like endurance and strength. A relaxed spin won't do much for those. Secondly, you will burn more calories over the same distance if you work hard and move fast.

True, but there are tons of variables. Two summers ago, I got a job 1.5 miles from home. Driving took longer than cycling, and of course, cycling is more fun, so that's what I did every day. I GAINED five pounds on my hips and thighs and my waist didn't grow, so it was all muscle growth. I definitely got stronger from just a little bit of cycling.

The cats, my friend, the cats. They are indeed strategically placed to increase the viewers' attention span, for sure, especially if the viewer is not a straight male (if he is, I gather from the comments that no extra animals are necessary to hold his attention ). Every time I was about ready to stop watching, a cat wandered by, or jumped on something, so I watched just a little bit more.
