One of the pleasures of a holiday is taking a break from your usual routines by turning off the alarm clock, lounging a little longer at dinner, and seeing friends when you normally might not have time. At the same time, taking a break from your routines is one of the things that makes it so difficult to get back into them post-holiday!
As you crawl back into the routines that you likely took a break from over the Memorial Day weekend, don't be too hard on yourself. Mondays and Tuesdays are never easy, but they can be a particular challenge after the holidays. You WILL get back to the gym when you're ready, and you WILL try that diet on for size again. Letting yourself break out of your routines for a couple days, however, is one of the most important occasional breaks you can give yourself.
