Learning about health and fitness is interesting and fun if you know about your vital measures. Take them by hand or with a fitness tracking device. If you want, you can even build your own device with a Physbot kit available from extensionpubs.osu.edu. No matter what you choose, you will come away with very useful life skills. A PDF is now available from the Oho 4-H Books and Resources web page. Printed copies will be available in October 2021. ©2021.
