What You'll Learn

This guide explains how Limberjack's recovery tracking system works and how to use it to make smarter programming decisions.

What Are Recovery Rates?

Recovery rates show you when movements and muscle groups are ready to be programmed again. Instead of guessing whether your athletes have recovered from yesterday's squats, you see clear visual indicators.

How Muscle Activations Work

Every movement in Limberjack has muscle activation data showing which muscle groups it works and to what degree:

  • High activation: The primary muscles doing the work (e.g., Quads for squats)
  • Moderate activation: Supporting muscles engaged during the movement (e.g., Glutes for squats)
  • Low activation: Stabilizing muscles with lighter involvement (e.g., Core for squats)

When you program a movement, its muscle activations determine how much load each muscle group receives. This accumulates across workouts to show aggregate fatigue.

Visual Recovery Indicators

Each muscle group shows a bar and one of four fatigue levels in words, so the level reads clearly without relying on color.

Low Recovered. Safe to load.
Moderate Some fatigue. Watch volume.
High Heavy fatigue. Consider waiting.
Very High Avoid loading today.

These levels appear as you build workouts, giving you immediate feedback on whether you're about to overload a muscle group.

Example: Weekly Programming

Let's say you programmed these workouts:

Monday: Heavy back squats (loads Quads, Glutes, Low Back) Tuesday: Overhead press (loads Shoulders, Triceps, Core) Wednesday: You're planning the workout

When you open the builder on Wednesday, you'll see:

Quads: Moderate partially recovered from Monday
Shoulders: High pressed overhead yesterday
Low Back: Moderate still recovering from heavy squats
Lats: Low not loaded yet this week

This tells you that pulling is wide open, legs can take moderate work, and heavy pressing should wait.

Muscle Groups

Limberjack tracks fatigue across standard muscle groups:

Examples: Quads, Hamstrings, Glutes, Shoulders, Chest, Back, Core, Triceps, Biceps, etc.

Each movement's muscle activation data determines which groups accumulate fatigue when programmed.

Recovery Timelines

All movements share the same default recovery rate. Limberjack calculates the recovery rank automatically using exponential decay over time: the longer since a movement was programmed, the more recovered it appears. You can override the recovery rate for specific elements within a training cycle if your programming philosophy calls for faster or slower recovery on particular movements.

Using Recovery Data to Program

The recovery system isn't meant to be rigid rules. It's information that helps you make better decisions:

  • See patterns you might have missed
  • Avoid accidental overload of specific muscle groups
  • Balance variety with consistency
  • Program with confidence knowing you're accounting for cumulative load
