Prevent cardio fatigue to keep you going

Ever wish you could do cardio, get beyond ripped and totally avoid cardio fatigue? Until now, this was seemingly impossible – a bodybuilder’s pipe dream – but breaking research shows that you can now do cardio, burn a lot of fat and still be amped after your session. And here’s the best part: It’s easy to do!

Scientists found that running speed and blood glucose levels were related. When study participants ran faster, the total amount of sugar in the blood decreased by a predictable rate. As this happened, concentrations of lactate also increased, leading to fatigue. Simply put, blood glucose levels are predictive of failure and fatigue when doing cardio. The researchers found that the most effective method of maintaining blood glucose levels was to drink a simple carbohydrate drink in divided parts, with an initial glucose load of 20 grams followed by subsequent doses of 5 grams each over the course of the cardio session.

FUSION FACT

The best way to not get fatigued during long cardio sessions is to maintain your blood glucose levels. Give this protocol a try during your next cardio session. This will help keep lactate levels from increasing, making sure that you don’t tire out before your time is up.
