More Sprints Less Jogging

The evidence keeps mounting against chronic cardio.

Why are you jogging six miles everyday?

Is it to get washboard abs?  To win a ribbon? Bragging rights?  Or perhaps your just a masochist who prescribes to the old saying “no pain no gain.”

The reality that chronic cardio may do more harm than good is a tough pill for me to swallow.  I love a good run.  Since summer started I’ve been doing 8 mile runs at least three times a weeks.  I thought I was doing good but since reading Mark Sisson’s Primal Blueprint I realize that I may want to trade my long runs for short intense sprint sessions.

Benefits of Sprinting

  • Increases testosterone production
  • Increases muscle fiber strength
  • Increases aerobic capacity
  • Increases muscle mitochondria
  • Increases insulin sensitivity
  • Increases human growth hormone production

Save Time

Not only does sprinting have more health benefits than excessive cardio training it also saves you time.  A 6 mile jog could take you an hour to complete, whereas a session of 10 sprints shouldn’t take you over 15 -20 minutes.

A normal sprint session should look like this:  Warm up/ stretch 5 minutes.  Start sprinting.  Each sprint should be between 10-30 seconds each with 30-60 second rest periods between each, or when you catch your breath.  After you have done 10 sprints you can cool down with some stretches.

You should never finish a workout feeling exhausted.  You will definitely feel it.  But it should be more of an invigorated buzz than a hands on your knees panting like a dog.
