They come in very handy for runners: pacers. People who run along to provide the right pace. All you have to do is follow their lead.
As a mom you can use pacers too! You just wanna be really careful who you choose. For example, I would not recommend Angelina Jolie as you personal mom pacer! She's already got her figure back, looks gorgeous all the time, while travelling all over the world with her six kids and shooting movies left en and right. These are the kind of pacers you need like another kids' drawing on your living room wall.
So it's very important to choose the right pacer. One you know you can keep up with.
I would like to introduce you to mine! Here she is! Isn't she best mom pacer ever?!
