There are many benefits associated with cardio and aerobic training, but also many negatives. Cardio training will lower your resting heart rate, lower blood pressure, keep your brain young by increasing circulation to the brain and aids in detoxification by stimulating the lymphatic system.
But long distance cardio training decreases testosterone levels, decreases the immune system post exercise, and raises stress hormone levels (cortisol). Increased levels of cortisol stimulate the appetite, will increase fat storing and slow down or inhibit exercise recovery.
So how do we get the benefits without the negatives? Burst train to burn fat.
Burst training involves exercising at 90%-100% of your maximum effort for 30-60 seconds in order to burn your body’s stored sugar (glycogen), followed by 30-60 seconds of low impact for recovery. This causes your body to burn fat for the next 36 hours to replace your body’s vital energy (glycogen) stores.
You only need to do 4-6 sets of 30-60 second bursts 3 times a week to see marked changes and improvements. More is not always better–make sure you have days of rest.
