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

Limberjack uses a combination of color and symbols to ensure recovery status is clear to everyone.

โ— Ready Fully recovered (< 55% fatigue). Safe to program.
โฌŸ Notice Minor fatigue (55-65%). Generally safe.
โ—† Caution Moderate fatigue (65-75%). Monitor volume.
โ–ฒ Warning High fatigue (75-85%). Consider avoiding.
โ˜… Danger Very high fatigue (85-95%). Do not program.
โœ– Stop Max fatigue (> 95%). Complete rest required.

These indicators 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: โฌŸ Notice partially recovered from Monday
Shoulders: โ— Ready fully recovered, only worked Tuesday
Low Back: โฌŸ Notice still recovering from heavy squats

This tells you that leg-dominant movements might be okay, but heavy posterior chain work 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

Different movement types have different recovery timelines based on intensity and volume. Limberjack calculates this automatically, but you can adjust recovery rates if needed for your specific programming philosophy.

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
