One Rep Max Property

The One Rep Max (1RM) Property allows coaches to prescribe exercise loads as a percentage of an athlete's maximum strength rather than entering a fixed weight value.

When used, CoachMePlus automatically calculates the prescribed weight based on a selected baseline measurement (typically a 1RM assessment) and the percentage entered in the exercise prescription.

This property is commonly used for strength training programs, periodized loading schemes, Olympic weightlifting, powerlifting, and return-to-play progressions.

What Does the One Rep Max Property Do?

The One Rep Max property converts a percentage of an athlete's stored maximum value into a prescribed training load.

Formula

Training Weight = Baseline Max × Percentage

Example

Athlete's Back Squat 1RM:

300 lb

Prescription:

80% 1RM

Calculation:

300 × 0.80 = 240 lb

The athlete will see a prescribed weight of 240 lb.

One Rep Max %

Determines what percentage of the athlete's stored maximum will be used.

Example

This allows coaches to prescribe training intensity without manually calculating loads for each athlete.

Shared Baseline

The Shared Baseline determines which stored performance measurement will be used to calculate the prescribed load.

Common examples include:

• Back Squat 1RM
• Bench Press 1RM
• Deadlift 1RM
• Clean 1RM
• Snatch 1RM
• Custom Strength Assessment

The selected baseline should correspond to the exercise being prescribed.

Example

Exercise:

Back Squat

Shared Baseline:

Back Squat 1RM

Stored Athlete Max:

315 lb

Prescription:

75%

Calculated Weight:

236.25 lb

Calculated Weight Increment

Determines the smallest weight increment that calculated values can use.

This helps ensure prescriptions match the available equipment in your facility.

Common Increments

Rounding Method

After calculating the prescribed load, CoachMePlus can automatically round the result based on the selected increment.

Round Down

Always rounds to the nearest lower increment.

Example

Calculated Weight:

236.25 lb

Increment:

5 lb

Result:

235 lb

Round Up

Always rounds to the nearest higher increment.

Example

Calculated Weight:

236.25 lb

Increment:

5 lb

Result:

240 lb

Why Use One Rep Max Programming?

Using percentages of a maximum allows training intensity to automatically scale to each athlete's ability.

Example

Workout Prescription:

5 Sets × 5 Reps @ 80%

Every athlete performs the same relative intensity despite using different absolute loads.

Common Use Cases

Strength Training

Prescribe loads based on:

• Back Squat 1RM
• Bench Press 1RM
• Deadlift 1RM

Olympic Weightlifting

Prescribe percentages of:

• Snatch
• Clean
• Clean & Jerk
• Front Squat

Powerlifting

Create percentage-based peaking and progression programs.

Return-to-Play Progressions

Gradually increase loading using percentages of pre-injury strength levels.

Team-Based Programming

Allow a single workout prescription to automatically individualize loading across an entire roster.

Example

A coach creates the following exercise:

Back Squat

• 4 Sets
• 4 Reps
• 85% 1RM

Configuration:

• Shared Baseline: Back Squat 1RM
• Weight Increment: 5 lb
• Rounding: Down

Athlete's Stored 1RM:

315 lb

Calculation:

315 × 0.85 = 267.75 lb

Rounded Down to Nearest 5 lb:

265 lb

When the athlete opens the workout, CoachMePlus automatically displays 265 lb as the prescribed training load based on their stored maximum strength value.
