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.

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.
