I invested a few minutes this morning configuring a timer for a high-intensity circuit training workout that I do. It’s less than 9 minutes long and can be done anywhere, and you feel great all day. In fact, there is almost never a reason to not do this workout before you shower in the morning. And better if you can do more than one circuit, but start with at least doing it every day before you commit to doing it more than one time per day.
The workout itself is available at ACSM’s Health & Fitness Journal website. And my time configuration is available at http://www.intervaltimer.com/timers/3184871, which you can import into a great $5 app called Seconds Pro – Interval Timer (that’s the iOS link, there is also an Android version at the Google Play store. The image on the right also links to the online timer.
