What Ive been told...
1. Fish oil
The cells in our body have "metabolic engines" known as
mitochondrion and peroxisomes. Omega-3 fats increase
levels of important enzymes that in turn boost the calorie-
burning ability of both cell engines. They can also increase
levels of fat-burning enzymes and decrease levels of fat-
Basically it was 1 ml of fish oil to 1 percent body fat... for a max of 4 weeks... then crank it down to 50% that level.
He went on about burning glycogen... the initial sprints burn up those glycogen reserves fast... so the more you stress your system to replenish, your body will start ganking energy from 'other' reserves (your fat stores) to replenish the glycogen. The more you burn up the glycogen (Glycogen forms an energy reserve that can be quickly mobilized to meet a sudden need for glucose)... the body will make it a priority to fill em back up.
So the deal is ... get your heart rate up to 90% of your max... then stop/rest and wait till your rate slows to 60% of your max... then blamo, back up to 90%... then repeat for 30 minutes. Do whatever exercise will get your bpm up ... doesnt matter. 3x a week
