Workout Reserve

I was taking a look at the blog, and their concept of Workout Reserve seems to be a copy of MPA. I’m not saying this to tattle, it’s more that they’ve seen a good idea in Xert, and copy it, or ended up there on their own. I wouldn’t be surprised to see TrainerRoad trying to implement something like MPA as well.

MPA isn’t that unique to Xert, is it? for instance as W bal graphs and allows you to plot them when designing workouts.

We skipped the whole W’bal thing because it’s flawed, fundamentally so. Anyone with a basic understanding of physics and human physiology would see this once you look closely at how it works. distinguishes between W’ and what they call Workout Reserve. It’s really quite interesting From their blog:

Q: What are the benefits of Workout Reserve vs. W’?

A: The benefit of Workout Reserve and its advantage over the W’ is that it’s a mathematical, not a physiology-derived construct. The likely fault in W’ is that It assumes an equivalent strain on the system across a variety of effort durations following the CP hyperbola. However, fatigue in the heavy and moderate domains is dynamic. Workout Reserve, therefore, is an umbrella that encapsulates physiology (integration of systems: nervous, respiratory, cardiovascular and musculoskeletal) into the performance potential without dwelling on how the performance/output is actually achieved. Beautiful in its simplicity we feel. Users might fall in love with this or may be critical. While our work is based on a deep understanding of physiology, our aim with the performance potential lies in practical application, bringing everything to a common denominator.

Q: Can I compute the Workout Reserve on my own?

A: Yes, have a look at the formulas in the pre-print paper (Zignoli 2023) at this link: they can be easily implemented in an Excel spreadsheet.
