Thought I’d pass this along. This is the training method developed by Dr. Phil Maffetone who has trained some very successful athletes (Mark Allen) using a very simple method that uses an aerobic base building method getting to get the body to fuel itself on FAT, not carbs. It’s a perfect match with a keto plan. A significant benefit of aerobic base building is the ability to run faster at the same effort, that is, at the same heart rate. A heart monitor can help objectively measure these improvements using a test he developed in the mid 1980s called the maximum aerobic function (MAF) test.
I live in the central valley of CA and I’ve used this training method to build an aerobic base such that I can get into high altitudes with minimal acclimatization. Last June I got to the top of Mt. Shasta (3rd time) with NO HEADACHE. This with minimal high altitude training last year due to high snow pack. I’ve done this twice now…it works well for me. Nothing quite like this out there that I’ve found. Hope someone finds it useful. I’d like to hear what the experience of others has been.
