The Rule of Thirds Framework

Balance exercise selection

Problem it solves

Individuals who struggle to build and sustain consistent behaviors in peak performance, relying on willpower instead of systems that make good actions automatic.

Best for

Individuals seeking to maximize recoverable volume

Not ideal for

Those who cannot commit to regular exercise

Overview

Why this framework exists

The Rule of Thirds Framework is a structured approach to exercise selection, dividing movements into vertical, horizontal, and lateral rotary categories. This framework aims to balance exercise selection to maximize recoverable volume and minimize fatigue. By allocating a third of exercises to each category, individuals can optimize their workout routine and improve overall fitness.

Core principles

3 total
  1. Balance exercise selection to avoid overtraining
  2. Divide movements into vertical, horizontal, and lateral rotary categories
  3. Allocate a third of exercises to each category

Steps

3 steps
  1. Identify Vertical Movements
    Select exercises that work multiple muscle groups, such as squats, deadlifts, and lunges.
    Pro tipFocus on compound exercises that target multiple muscle groups
    WarningAvoid overdoing vertical movements, as they can be taxing on the body
  2. Identify Horizontal Movements
    Select exercises that target the glutes, such as hip thrusts, glute bridges, and back extensions.
    Pro tipIncorporate horizontal movements to target the glutes and minimize fatigue
    WarningBe cautious not to overdo horizontal movements, as they can still be taxing
  3. Identify Lateral Rotary Movements
    Select exercises that target the glute medius and minimus, such as hip abductions and lateral band walks.
    Pro tipIncorporate lateral rotary movements to target the glute medius and minimus
    WarningBe mindful of proper form and technique when performing lateral rotary movements

Example Workout Routine

A sample workout routine using the Rule of Thirds Framework might include 3 sets of squats, 3 sets of hip thrusts, and 3 sets of hip abductions, performed 3 times a week.

OutcomeImproved overall fitness and increased recoverable volume

Common mistakes

3 traps
Overdoing Vertical Movements
Failing to balance exercise selection can lead to overtraining and fatigue
Neglecting Horizontal Movements
Failing to incorporate horizontal movements can lead to imbalanced development
Ignoring Lateral Rotary Movements
Failing to incorporate lateral rotary movements can lead to neglect of the glute medius and minimus

Origin story

How this framework came to be

The Rule of Thirds Framework was developed by Dr. Bret Contreras, inspired by his work with strength coaches and observations of athletes' recovery patterns. He recognized the importance of balancing exercise selection to avoid overtraining and maximize results.
