There's no way I'd get my husband to do any Cathe tapes. He'd claim it's because he doesn't get into working out to a tape - but I KNOW he knows that he couldn't keep up. Plus, he knows he'd look silly doing "girly" moves.
Actually, I caught a glimpse of my reflection in the window while doing KPC and I look like a total dork myself!
DH got a wake-up call when he went cycling with me one day. I have one of those trailers for toddlers that you attach to the back. It adds probably a 40+lb drag to your bike, but I'd take it 10 miles a coupld times a week. The one day he went with me and I had him put it on his bike, he couldn't do it. What a wimp! (for the record - he's probably about 80 lbs. heavier and a foot taller than me, so he really SHOULD have been able to do it as well as me).
