Today's Exercise Check Up

Okay, so I've been KICKING BUTT on the bike lately, to the tune of 7.5 miles in 30 minutes!I love my own butt - it's getting SWEET! I can also walk 4 miles on the treadmill. I decided to do some moving things around this afternoon that resulted in my having to walk about .7 miles home on a paved road...no problem, right? Yeah, no problem my aching thighs and calves! Apparently walking isn't as easy on real roads as it is on the treadmill...
