Third Workout in a Row

It's back to work for me tomorrow, so I hit the gym again today, my third workout in a row. To be honest, I wasn't really into it today. I stuck it out for 25 minutes on the recumbent bike, coaxing myself through 5-minute segments. Then I did some hammer curls, bicep curls, and shoulder presses with 5-lb dumbbells. Still bleh. Now that I'm home, I'm glad I did it. But I'm not used to three days of exercise in a row, and I felt it in the workout. Maybe I just need to shake things up a little bit. And maybe I need some rest.
