“Time to raise that heart rate! Join Jeff for an accessible heart-pumping interval routine that you can do on any piece of equipment (treadmill, rower, elliptical, etc.). You can even opt to walk or jog along and up your intensity at Jeff’s cues – no equipment necessary! You’ll have two full minutes of recovery time after each one-minute work interval, so this is a great choice for beginners.
