Pushing For Performance
HIIT Methods: Sled Training
A good high intensity interval training (HIIT) session creates a disturbance of metabolic homeostasis while minimizing stress on the joints and / or compression of the spine. Pushing a sled meets both of those goals. Sled sessions are time efficient, and they have the added benefits of improving leg strength, core stability, and they make you better at nearly every daily challenge. A well designed HIIT sled training protocol allows you to assess performance and track progress. Presented below are four of my most frequently prescribed sled HIIT protocols. Ditch the elliptical, cancel your Zumba sessions, and for the next month, give these a try.
I cannot tell you how much weight to use on the sled. In general, men can start with bodyweight and women with half to two thirds bodyweight loads. You will quickly learn if you have too much or too little on the sled. Any progressive gym will have several sleds and plenty of open space. The trainers at Fenton Fitness can get you started.
30 / 30 Protocol: Place a stopwatch so it is visible on the sled. The load on the sled should create a thirty second interval exertion rating that feels “easy”. Push the sled for thirty seconds and then rest for 30 seconds. Perform eight intervals.
10 – 20 – 30 – 10 – 20 – 30 – 10 – 20 – 30 Yard Interval: Load your sled and start the timer. Push the sled for 10 yards and rest twenty seconds. Push the sled 20 yards and rest twenty seconds. Push the sled 30 yards and rest twenty seconds. Repeat 10, 20, and 30 yards two more times. Finish all of the intervals and you will have covered 180 yards. Record your time.
60 – 30 – 15 Yard Interval: Be careful that you do not use too much load for this HIIT sled session. Push the sled 60 yards. Rest thirty seconds. Push the sled 30 yards. Rest thirty seconds. Push the sled 15 yards. Record your time.
15 Yards Times Ten: Use a load on the sled that allows you to move at a fairly steady pace. Think racehorse, not plow horse. Place a stopwatch so it is visible on the sled. Start the timer and push the sled fifteen yards. Rest ten seconds and then push another fifteen yard push. Perform ten, fifteen yard intervals. Record your time.
