Cracking the Code: My Physiology First Tabata VO2 Max Deep Dive

A comparison graph showing cumulative average power decay over three Tabata sets, highlighting higher initial intensity in Set 1 and more stabilized power in Sets 2 and 3.

Cracking the Code: My Physiology and the Tabata Triple Threat Preface: The Metabolic Green Light vs. The CNS Red Light Before I even turned a pedal, the data was already telling a nuanced story. I woke up with a solid 83 sleep score and a body battery that recharged to 85—clear signals that my recovery […]

Altitude, Heat, and the Power Curve: Practical Physiology for Endurance Athletes

Two people in conversation at an outdoor table with rolling hills and cloudy sky behind them

Elite performance is built on a careful balance between stress and recovery, biology and behavior. This article translates practical lessons from applied sports science into usable guidance for endurance athletes and coaches. It covers how simulated altitude works, why erythropoiesis is not as simple as “more red blood cells = better,” how heat affects different […]

Using Ergometer LOAD vs. % SLOPE for DFAA-1 Base Training

DFAA-1 Base Ride Data Using Ergometer Mode

“PerfPro Studio is such a fantastic product for training and analysis. It allows a cyclist to ride at a load based on an ergometer, or a load based on % slope. Yesterday, after assessing my DFAA-1 heart rate, SmO2 and wattage values, I decided to ‘test’ the values….”

The Road to 300 Watts FTP

Moxy DFAA-1 Vo2master PerfPro Studio

Right Now, It’s NOT about 300 Watts; It’s About Raising LOWER THRESHOLD

The goal of base is to train the body for Economy. Stamina is the fundamental Pillar for Polarized Training. When you train using DFAA-1, you can get a clearer picture of how your body is responding to the training. Wattage and traditional heart rate become

DFAA1 – Curb My Enthusiasm

Using DFAA-1 to determine whether to continue with a ride, or call it a day.

I thought A Good Night’s Sleep Would Lead to A Good Ride. My Heart Said Otherwise It’s frustrating – today’s ride started off with the best of intent. However, the FatMaxxer App, monitoring the DFAA1 fractions on my Heart Rate Variability, showed more strain than my wattage allowed. In other words, for the PRESCRIBED Heart […]

The Heart KNOWS Best.

It's really critical to get a good night's rest before assuming a good day's ride. Garmin Connect Sleep Score can help me predict good watts and heart rate with a good DFAA-1.

DFAA1 With the Help of FatMaxxer and Garmin Connect Sleep Leads to a GREAT RIDE! My economy is up, my heart rate is down, my weight is down, and my power is up. SmO2 is also tracking, and I’m starting to adapt. I know none of this is new, but I do enjoy blogging the […]

October 9 2021 Post-Ride Analysis

DFAA-1, Moxy, and Vo2Master ALL worked to help with traditional 'base' measurements of Zone 2 heart rate and wattage.

Bouncing Between DFAA1 0.75 and 1.00 for Optimal Fat Burn and Aerobic Base Improvement   Having the FatMaxxer Android software on-screen in realtime has brought a new element to my base training. I use the screen to try and keep my intensity between DFAA 1.00 and 0.75. The advantage to this is that I can […]

Base Ride Number 2 – Pre-Brief

Garmin Sleep Score is a result of good weight management, lower intensity, and recovery.

Ya Gotta SLEEP in order to PERFORM! Apparently, the winner of this year’s Tour de France, who also won the race LAST YEAR, has a secret. He knows how to SLEEP and RECOVER. I obviously do not. I’ve tried everything; blackout curtains, weighted blankets, cold room, no caffeine past 10am, less than two beers a […]

First Ride Using FatMaxxer For Aerobic Conditioning

First Ride with Fatmaxxer App

Trying to Keep DFAA1 Between 0.75 and 1.00 Today’s Ride was just the first step in what will arguably be a four to six week effort to establish a BASE of AEROBIC Fitness. I rode just under 60 minutes, and used the information from FatMaxxer to keep my riding intensity at maximum aerobic intensity. Yesterday, […]
