Sunday is a day of rest.  But try not to sit on the couch all day, you will feel better if you move around a bit but don’t “exercise” today.  Do some pull-up’s on the playground,  walk the dog, walk your spouse, or just walk around the block (or mall).  Enjoy your day away from strict routine.  This would also be a great time to get your food prepared for the week.  Go to the grocery store and get some healthy foods you enjoy.  Happy Sunday!
