Day 12 – HiLo40 - Sprint Level
“Survival can be summed up in three words – never give up. That’s the heart of it really. Just keep trying.”
- Bear Grylls
Today’s workout is called HiLo40. This session is designed to improve your endurance, aerobic power and fuel economy. First we partially deplete your body’s carbohydrate stores with 10 minutes of sprint work (Hi), in turn, forcing your body to use more fat as a fuel during the Lo portion of the workout, a 30 minute run at your race pace. Training in this way builds fitness faster than either Hi or Low training by themselves.
Dynamic warm-up - 3 movements x 3 at 25 yards each
