75 XSS for 75 Days – First 14 Days

75 XSS for 75 Days – What’s Happening to my Fitness? XSS Stands for Xert Strain Score. It’s a way to combine time and energy at different intensities. It’s a measure of Cycling Volume. While I unofficially began thinking about this goal in late May, I announced the plan on this forum later, in Mid […]

75 XSS (Per Day), for 75 Days: A New Self-Challenge

75 Days of 75 XSS (Xert Strain Score) Points – Let’s See Where This Leads 75 XSS per day, roughly 5 days per week? Can I achieve this? The Xert Strain Score (XSS) is a volume-measuring tool that looks at a cyclist’s time, wattage, energy expenditure, and overall fitness signature. The calculation is unknown, but […]

Xert Breakthrough With Physiological Metrics

Xert Is On Board With Some Serious Physiological Observations My Client, Dusty, achieved an Xert Breakthrough while I observed his Physiological Metrics. This is Part 2 of what will now be a 3-part series of videos. In Part 1, I described the physiological phenomena behind a good warmup. Today, we’re going to show how Xert […]

Why A Coach Will Help You

A Coach Will Help You Salvage A Workout, Better Than Any Prescibed Program Failing a workout is always frustrating. A good coach will help you understand why, and how, but a great coach will help you get something good out of that workout. This will help you physically, physiologically, and mentally. Let’s find out why. […]

Xert Breakthrough With Physiological Metrics Part One – Warmup

We Use a Moxy Monitor, a Vo2 Master, PerfPro Studio, and Xert To Show a PROPER Warmup I continue to learn something almost daily when it comes to mixing Physics and Physiology. The data that we get and use for wattage training, is almost always complemented by the information I collect from physiology. We have […]

Xert FTP Tested

Xert Claims my FTP (Functional Threshold Power) Sits At 265 Watts. Is It Accurate?

I’ve always wondered if calculated Functional Threshold Power Values are accurate. Since 2017, however, I have relied on the Xert FTP value.

For years, we relied on the “20-Minute” Test. Riders would perform a 20-Minute effort, all out, and then subtract 5% from that value. The new number was considered “Threshold”.

Later, physiologists looked at 90% of a 3-Minute Maximal Effort.

There’s the 5-1-5 test….

Step Tests (25w steps every 3 minutes)…

Ramp tests (15-20w every minute)…

The latest ‘Testing’ asks for a 20-minute, 5-minute, 1-minute, and 5-second effort.
