Poor Linda. Her glutes are so sore from all the classes she is teaching that she can't get up the stairs very well. Today, she told me she taught 2 Body Pumps; 1 TKD class and then did 30 minutes on the stair mill. To cheer her up, I found this funny joke about Big Foots (or is it Big Feets?) doing aerobic classes. Check out that booty on the instructor Foot!
