Definitely. I've recently started exercising more. My bare minimum commitment to myself is to walk a half an hour a day. I regularly do more, but if I only do 30 minutes I don't feel guilty. No matter how long of a day I've had, I'm never too tired to walk for 30 minutes. It's also a good way to build self control through habit.
