Is your workout schedule on auto pilot? Monday-treadmill, Tuesday-upper body, Wednesday-elliptical, Thursday-lower body, Friday-spinning class. It's predictable and boring. Take some time to mix it up. Instead of the treadmill Monday, go to that hot new Salsa cardio class you've been wondering about. On Thursday, if you normally only use machines, throw in some squats and lunges using free weights. Make a Saturday date to run or hike with a friend. Ride your bike to work Friday instead of going to spinning class. When my workout gets too routine, I find that I just go through the motions. That's when I know it's time to mix it up. How do you vary your routines?
