Is there a better sound on planet earth than a baby's laughter? I think not!

Lauren Pak is a prime example that you don't have to let your fitness fall by the wayside when you become a mama. She has found a way to get her workout in while entertaining her sweet boy, Kendrick at the same time!

Kendrick's giggle is motivation for Lauren to do more sit-ups! Everybody wins!

Lauren and her husband Jason own a gym called Achieve Fitness in Boston so physical health is extremely important to their family. Baby Kendrick is already learning the importance of staying active and he is only four months old! This fit family is pretty awesome. Thanks for sharing this sweet moment with us, Lauren!
