Fitness and health are a lot like that, yet it's not only easy to put ourselves on the back burner, it's fairly common. Too often, it's expected. Women are not "supposed" to be selfish. If you're a caregiver, you come second. At least, that's what we've been taught to expect, to believe, to act like.
There's a great article from Precision Nutrition that addresses this issue and even did an informal study of their female clients. Read it here: "who takes care of YOU?" If you read all the way to the end, note that it essentially turns into a sales pitch for the Precision Nutrition system. It's not a hard-sell though, and the rest of the article is a good reminder on this Mother's Day that we all - women, men, parents or not - need to take care of ourselves first, so that we can care for others.
It's not selfish.
People watch what you do. Especially little people. Lifting weights will make you strong; leading by example will empower others to be strong, too. Moms can be mighty powerful. If you happen to be one, Happy Mother's Day.
