Training Load Calculator (1RM Zones)
Calculate training zones based on your 1RM. Optimize periodization and progression with accurate load percentages.
Input Data
How It Works
Training zones are based on 1RM percentages and determine the number of repetitions and training objective. Each zone targets a specific physical quality.
Clinical Use
Essential for training periodization, load progression, and strength program planning.
Frequently Asked Questions
What is 1RM?
1RM is the maximum load that can be lifted in a single repetition with correct technique.
How to determine my 1RM?
It can be tested directly or estimated using formulas based on submaximal repetitions.
Which zone to use for hypertrophy?
For hypertrophy, 70-85% of 1RM is recommended, with 7-12 repetitions.
How often should I retest 1RM?
It's recommended to reassess 1RM every 4-6 weeks to adjust training loads.
Frequently Asked Questions
What is training load?
Training load refers to the total amount of work performed during training, considering both external load (objective measures like duration, distance, weight) and internal load (subjective/perceptual measures like RPE, heart rate). It is crucial for optimizing performance and preventing overtraining.
How is RPE-based training load calculated?
Session RPE (sRPE) = Training duration (minutes) × Average RPE (1-10 scale). For example, 60 minutes at RPE 5 = 300 arbitrary units (AU). This simple method allows comparison of load across different training modalities.
What is the acute:chronic workload ratio?
ACWR compares the current week's training load (acute) to the average of the past 4 weeks (chronic). Ratios between 0.8-1.3 are considered safe. Ratios > 1.5 indicate high injury risk. This metric helps guide training progression.
How can I prevent overtraining?
Monitor training load weekly, ensure adequate recovery between sessions (especially high-intensity), vary training stimulus, prioritize sleep (7-9 hours), maintain proper nutrition, and watch for signs of overtraining (persistent fatigue, decreased performance, mood changes).
