Workout library

The workout library holds the standalone workouts you build in the workout editor. Open it from Training Plans → Workouts. Use labels to organize the library with your own categories, then combine filters and search to find the right workout quickly.

​

Build a workout

Click Create Workout to open the editor. Pick an activity type (Run, Cycling, Swim, Hike, Walk, or Strength) and give the workout a name and description, then build its structure from the block palette.

​

Blocks

A workout is a sequence of blocks. The palette offers ready-made block types — Warm-up, Run, Recovery Run, Cool-down, and Interval — plus a Container block for grouping steps that repeat together and a Basic block for anything else. Click a block type to add it to the sequence, then select it to configure:

• Block Length Target — either Distance (Pace Range) or Duration (Heart Rate Range), depending on how you want to prescribe the segment.
• Block Intensity Target — a Pace Zone (Z1 Recovery through Z5 VO2 Max) or a custom pace/heart-rate range. NexRex loads the athlete’s own zones when available and falls back to default guidance if it can’t find any.

​

Interval blocks

An Interval block is a container: drop Run and Recovery blocks inside it, then set a Repeat Count for how many times the pattern repeats. Garmin devices cap repeats at 1–30, so NexRex enforces the same limit here to keep exported workouts device-compatible.

​

Preview and save

The editor shows the workout’s intensity profile as you build — bar width is distance or time, bar height is the zone — the same preview used in the library picker (see Preview before loading from the library below). Save when the structure is ready; only standalone library workouts get the Labels field described next.

​

Label a workout

Labels are short, coach-defined tags on a library workout, such as “track”, “base phase”, or “return from injury”. When you create or edit a standalone library workout, the editor shows a Labels field.

1. Open a workout from Training Plans → Workouts, or click Create Workout to start a new one.
2. In the Labels field, type a label and press Enter to add it.
3. Remove a label by clicking the remove control on its chip.
4. Save the workout.

Rules for labels:

• Each workout can have up to 5 labels.
• A label can be up to 40 characters long.
• NexRex trims surrounding whitespace and rejects empty labels.
• Duplicates are rejected. Matching is case-insensitive, so “Track” and “track” count as the same label.

Workouts saved before labels existed simply have none. Add labels the next time you edit them.

​

Who can edit labels

Only coach-side roles (assistant coach, coach, head coach, admin) can add, change, or remove labels. If an athlete submits labels when saving a workout, NexRex rejects the request.

​

Where labels apply

Labels exist only on standalone library workouts. The editor does not show the Labels field when you build a workout inside a training plan, a plan instance, or directly on a calendar day, and labels are not copied into those contexts.

​

Filter and search by label

The library’s filter bar has three category filters: Activity, Sub Type, and Labels. The Labels dropdown lists every label currently in use across your library, sorted alphabetically. Pick one to show only workouts carrying that label, or choose All Labels to clear it. Filters combine: selecting an activity type, a sub type, and a label shows only workouts matching all three. Labels also participate in text search. Typing in the search box matches against a workout’s name, description, type, activity type, and labels, so searching for “track” finds workouts labeled “track” even if the word appears nowhere else. Each workout card in the library shows its label chips, so you can scan categories at a glance.

​

Preview before loading from the library

The Library button in the workout editor opens the same library as a picker. It has the same search box and Labels dropdown, so you can narrow by label there too, and its search matches labels as well as names and descriptions. Each card shows its label chips. Click a workout card to preview it in the bottom half of the picker before loading it. The preview shows the workout’s intensity profile (bar width is distance or time, bar height is the zone), the block sequence with repeat counts, and the total distance, estimated time, and step count. Click Use this workout to load it into the editor. If the editor already has blocks, NexRex asks you to confirm the replacement first.
