Xert Magic Buckets (XMB) – Knowledgebase

Magic Buckets is an Xert training feature that helps athletes efficiently reach daily Low, High, and Peak XSS targets by dynamically adjusting interval intensity, duration, and recovery. It offers both structured and flexible real-time training options, adapting to accumulated strain and real-world conditions to optimize energy system development.

Definition

Magic Buckets (XMB) is Xert’s training feature that helps you hit your daily Low, High, and Peak XSS targetsefficiently. Using an adaptive algorithm, it calculates the interval intensity, duration, and recovery needed to accumulate the right amount of strain across your three energy systems.

You can use Magic Buckets in two ways:

Real-time data field: adapts continuously during your ride, turning any ride into guided training.
Generated workout: creates a customizable structured workout you can send to supported apps/devices.

What It Represents

Xert is based on the idea that effective training balances strain across three energy systems, depending on your goals as an athlete. To improve a specific aspect of fitness, you need to apply strain to the corresponding system:

Low XSS — Endurance / aerobic development; trains your Threshold Power system
High XSS — Sustained hard efforts above threshold; trains your HIE system
Peak XSS — Short explosive efforts; trains your Peak Power system

For example, if you want to improve sprint power, you’ll need more Peak strain. Magic Buckets makes this practical by guiding you—either in real time or via a generated workout—toward the right Low/High/Peak balance for the day.

Note: Magic Buckets is not about holding a specific power target. It’s about accumulating the right strain (XSS) in the right systems.

How Magic Buckets Works

Magic Buckets looks at:

What you've already accumulated today (including earlier rides), and
What Low/High/Peak targets remain

It then calculates the most efficient interval and recovery guidance to fill the remaining buckets. In the real-time data field, this guidance updates dynamically as your ride unfolds—so you don’t need the “perfect” stretch of road to execute intervals.

Common Misunderstandings

Magic Buckets isn’t “cheating” training - it’s a more flexible way to hit the same training targets.
You don’t need perfect terrain or a perfect route - Xert adapts targets based on what’s available.
Group rides and races can still count. You can accumulate strain during the ride, then “top up” what’s missing afterward.
