I always do small workouts during the week. For example, this week, I ran 2 miles on Monday morning, did Jillian Michaels on Tuesday morning, did a Denise Austin ab workout yesterday morning and last night I changed things up a bit. Instead of my normal "medium" run, I did steps.
Our town is the home of the William McKinley National Monument. There are 108 steps. I only did 3 laps but it is a good workout! This morning I was back to a 2 mile run on some sore legs!
