# One-Rep Max Estimator MCP. AI Agent Connect

> One-Rep Max Estimator MCP uses mathematical models to turn your submaximal lifting data into accurate strength predictions. Instead of guessing your limits, you can use your AI client to calculate predicted maximums, generate training intensity charts, and understand the statistical margin of error for any exercise you perform.

## Description

Stop guessing your training loads. This MCP applies multiple mathematical models to the weight, reps, and RPE you record during your workouts. If you've just finished a set of five reps at a specific intensity, your AI client can instantly translate that data into a predicted one-rep max. You aren't stuck with a single formula; you can compare different models to see which one is most reliable for your specific lift. It also handles the tedious math of programming. You can generate full percentage tables to see exactly what your training weights should be for any given intensity. Because every lifter is different, the MCP also provides confidence intervals so you know the statistical range where your true maximum likely sits. It's a way to bring high-level strength science directly into your chat interface.

## Tools

### get_estimated_1rm
Calculates your predicted maximum weight using several different mathematical models.

### get_confidence_interval
Provides the statistical range where your true one-rep max is likely to fall.

### get_formula_comparison
Compares various mathematical models to show which one is most reliable for your data.

### get_percentage_tables
Generates a list of absolute weights based on specific percentages of your estimated max.

## Prompt Examples

**Prompt:** 
```
I just did 5 reps of 100kg bench press at RPE 8. What is my estimated 1RM?
```

**Response:** 
```
Your estimated 1RM for bench press is 120kg.
```

**Prompt:** 
```
Show me a percentage table for a 200kg squat.
```

**Response:** 
```
For a 200kg squat, your training weights are: 50%: 100kg, 60%: 120kg, 70%: 140kg, 75%: 150kg, 80%: 160kg, 85%: 170kg, 90%: 180%, 95%: 190kg.
```

**Prompt:** 
```
How much error should I expect for a 3 rep set of 150kg deadlift?
```

**Response:** 
```
The estimated 1RM is 165kg with a confidence interval of 158kg to 172kg.
```

## Capabilities

### Strength Forecasting
Your agent uses submaximal lift data to predict your absolute maximum.

### Intensity Programming
The AI generates weight breakdowns for specific training percentages.

### Model Validation
Your client compares different formulas to find the most accurate prediction.

### Error Margin Analysis
The tool calculates confidence intervals to show the reliability of a prediction.

## Use Cases

### Calculating Training Loads
Your agent generates a weight table so you know exactly what 75% of your max is for today's session.

### Predicting Meet Attempts
Use recent training sets to estimate what you might be able to lift on a single attempt.

### Validating Progress
Compare different mathematical models to see if your strength gains are consistent across formulas.

### Assessing Accuracy
Check the confidence interval of a prediction to decide if a heavy set is safe to attempt.

## Benefits

- Removes the guesswork from calculating training loads.
- Provides multiple mathematical perspectives on a single lift.
- Automates the creation of percentage-based training tables.
- Quantifies the uncertainty in strength predictions.

## How It Works

Connect the MCP to your preferred client and start feeding it training data.

1. Connect your AI client to Vinkius.
2. Input your recent lift data, including weight, reps, and RPE.
3. Ask your agent to calculate your estimated 1RM or a percentage table.
4. Review the mathematical models and confidence intervals provided.

## Frequently Asked Questions

**How does this MCP calculate my max?**
It applies multiple mathematical models to the weight, repetitions, and RPE you provide from your submaximal sets.

**Which AI clients can I use with this?**
You can use this MCP with any compatible client like Claude, Cursor, Windsurf, or VS Code.

**Can I get training weights for specific percentages?**
Yes, you can use the percentage tables tool to see exactly what specific percentages of your max look like in absolute weight.

**Does it account for error in the prediction?**
Yes, the confidence interval tool calculates the statistical range within which your true maximum likely falls.

**Is this just one formula?**
No, the MCP uses multiple models and allows you to compare them to see which is most reliable for your specific lift.
