15 Minute HIIT: Workout to Burn Fat & Sculpt a Tighter Body

Please follow and like us:

Hi Everyone!

Today’s workout is quick, 15-minutes per round, but you can repeat it to create a more intense and longer workout. This is a full body workout. I use a dumbbell and a stability ball in this workout, but I also provide alternate exercises for those of you that don’t have a stability ball.

The weight is optional, but I recommend it because it will increase the burn & challenge of the workout.

As always, when doing a HIIT workout you really want to push yourself to get in as many reps per exercise as you can. However, do not sacrifice form. Less reps with great form is better than more reps with poor form.

I started several new articles, including a pregnancy workout update to share my progress and workouts thus far. I have to finish them up, but I will get them posted at some point this weekend.

I hope you all enjoy the workout! Fit Fashion in this video is from and you can always get 15% off your total order with the code BenderFitness at checkout.
