Lacey Stone’s Exclusive Fitbit Charge HR Workout #2


Welcome to Fitbit Charge HR Workout #2. If you haven’t conquered Fitbit Charge HR Workout #1, go do it now. The Fitbit Charge HR workouts in my four-week plan build on each other, so it’s important to do each workout three times in one week before moving on to the next. Got it? Cool!

Tips to Get Started

Loop the entire circuit two times, for a total of three rounds—which means you’ll be doing all seven of the exercises straight through, and then repeating the circuit again two more times.

After the first circuit, rest for 1 to 2 minutes max before starting the second circuit. Then rest again before going into your final round.

Since Fitbit Charge HR tracks your heart rate, I’ve included Heart Bump moves to give you a big bump in your heart rate. The moves will be challenging, and should elevate your heart rate to your max heart rate (MHR), which is about 171 bpm to 190 bpm. (Your heart rate will respond according to your personal fitness level.) Listen to your body and take a one-minute break if you need one.

During your workout, you’ll be in your Steady Set Heart Rate (SSHR) Zone, which could range from 133 bpm to 170 bpms, depending on your fitness level.

For all exercises use a weight that’s heavy enough that by the second set you feel like you might not be able to lift the weight for the last reps. In the pictures, I’m lifting weights that work for me. I recommend that you lift heavier for fastest results. However, form is king, so please don’t get overly ambitious.

This workout is 24 minutes, and you should aim to keep your heart rate in your SSHR Zone (between 130 and 170 bpm, depending on your fitness level). Stick with me for three more weeks and I’ll help you feel stronger than ever!

Before you start Fitbit Charge HR Workout #2, do a light jog on the treadmill for two to three minutes to warm up.

Ready. Set. Go: Fitbit Charge HR Workout #2!

  • My question is about the accuracy of the fitbit during heart pumping exercises. I’ve been doing anaerobic routines but the fitbit sometimes only gets to 115-120 bpm while my heart has leapt from my chest and is running down the hall on it’s own. any suggestions?
