Open Exercise Data
OrthoRep is built on transparency. Every exercise, every strength standard, every algorithm is open for inspection. No black boxes, no hidden formulas.

Data Sources
Our strength standards are estimated using pattern-based methodology derived from exercise biomechanics:
Movement Patterns
Compound vs isolation, push vs pull, upper vs lower body
Data used: Base strength multipliers by movement category
Equipment Adjustments
Barbell, dumbbell, cable, machine variations
Data used: Equipment-specific weight modifications
Training Principles
Established biomechanical and physiological principles
Data used: Bodyweight ratios, unilateral considerations
User Feedback
Anonymous community data from opt-in users
Data used: Calibration improvements over time
Standards are approximate estimates that improve with your workout history. See the methodology section below for details.
Methodology
Strength Standards
Bodyweight multipliers representing typical performance at each experience level. We use the average of multiple sources, adjusting for equipment type (barbell vs dumbbell) and movement pattern.
- Standards expressed as bodyweight multipliers (e.g., 1.5x = lift 1.5× your bodyweight)
- Dumbbell exercises show per-dumbbell values
- Separate standards for male and female lifters
- Five levels: Untrained → Novice → Intermediate → Advanced → Elite
RPE Prescriptions
Based on the Reactive Training Systems methodology, mapping Rate of Perceived Exertion to Reps in Reserve. Each RPE level has recommended sets and rep ranges optimized for that training zone.
- RPE 5-6: Technical practice and volume accumulation
- RPE 7-8: Primary strength building zone
- RPE 9-10: Near-maximal and maximal efforts
- Rep ranges adjusted to maintain target RPE across the set
Weight Suggestions
Two-tier system: bodyweight-based starting estimates for beginners, and 1RM percentages for experienced lifters. Equipment adjustments account for mechanical differences.
- Bodyweight multiplier × equipment adjustment = starting weight
- RPE-to-1RM percentages based on RTS research
- Warmup set recommendations scale with working weight
- Automatic adjustment for unilateral vs bilateral exercises
Exercise Scoring
EMG (electromyography) scores rate muscle activation effectiveness. Higher scores indicate greater target muscle activation relative to secondary muscles.
- Scores 1-10 based on EMG research
- Compound movements can score high for multiple muscles
- Beginner-friendly flag indicates lower technical demand
- Difficulty rating considers coordination and injury risk
