This is a simple and short HIIT option that I use to finish off my workouts. 30 seconds of sprinting - and I mean really push yourself here - and 30 seconds OFF the treadmill. Repeat this 10x (10 minutes) Like and save this video to try it out later, and share the knowledge! 💙 #strongin60 #HIIT #treadmillworkout #burner #finisher #treadmillchallenge #sprinting #cardiotraining #cardio #fitnessjourney #fitness #letsgetit #oneractive #fitnessmotivation #bbb23 #esteira #treino #treinoemcasa #onlinecoaching #personaltrainer
