Go fast to go slow

My buddy, David Jass, was talking last night over a vodka tonic about fat burn. Ironic isn't it. He was tell ling Nelson and I that we actually burn more of our fat reserves by going slower. Nelson and I had just done an hour and thirty minute run at an extremely low heart rate. It was painful. It is actually easier to run faster that slower! I think your body has a natural rhythm and pace and when you alter it faster or slower its tough. He was saying that when you run fast your body gets energy from the first and fastest place it can, the food you recently ate. When you go slower your body doesn't need the energy immediately so your body gets the energy from fat reserves, in my case love handles. I thought this was great info. I know it works because we have been building our base by running at slower heart rates and I have been losing weight. We have also been lifting more which is also a low heart rate workout. Apparently we have to go slow now, build our aerobic engine, and work on fast later. I have the slow part down we will see how the fast part turns out. C ya. Move Faster.
PS Schmidty I did spellcheck this!
