How to use Muscle Imbalance Detector
Detect left/right and agonist/antagonist imbalances from strength tests with corrective priorities.
Choose measurements that describe your actual session or situation, confirm the units, then calculate. Read the result alongside its assumptions and use the tool again when your inputs change.

Right leg press (kg)
Enter a measured or estimated value (minimum 20) (maximum 300), using the unit indicated in the field label.
Bench press 1RM (kg)
Enter a measured or estimated value (minimum 20) (maximum 300), using the unit indicated in the field label.
Barbell row 1RM (kg)
Enter a measured or estimated value (minimum 20) (maximum 300), using the unit indicated in the field label.
How to interpret the output
Follow the tool-specific testing protocol and review any unusual outcomes with a qualified professional.
Repeat measurements using similar conditions when monitoring trends. Numerical predictions can vary with input accuracy, measurement method and individual circumstances.
Limitations and responsible use
Small asymmetries are normal. Significant imbalances (>15%) or those causing pain should be addressed with professional guidance.

What does the Muscle Imbalance Detector estimate?
Detect left/right and agonist/antagonist imbalances from strength tests with corrective priorities.
Which information do I need for this specialized tool?
Provide Left single-arm bench (kg), Right single-arm bench (kg), Left bicep curl (kg), Right bicep curl (kg), Left leg press (kg), and any additional fields shown above. Use your own relevant measurements and the units indicated in each field.
How should I interpret the result?
Follow the tool-specific testing protocol and review any unusual outcomes with a qualified professional. Compare results with your goals and other relevant observations rather than using a single output to make a major decision.
