15 Min. SIT | Sprint Interval Training w/ Vest | Dr. Stacy Sims | Next Level

Hey Team, I am loving these SIT Workouts! The intensity from the quick sprints and longer recovery not only changes your body but COMPLETELY breaks up the monotony! The added WEIGHT VEST had my heart rate up Especially toward the last 3 sprints. It’s hard to determine if it was because my heart rate was still up or I just went harder. That’s it, be fit!
