# Back-off Set Planner AI Agent Connect

> Back-off Set Planner MCP handles the heavy lifting for your strength programming. It calculates weight, reps, and set counts to bridge the gap between heavy top sets and the volume needed for hypertrophy. Your AI client uses these tools to ensure you hit your volume goals without overtraining.

## Description

Stop guessing your accessory work. This MCP gives your AI client the math it needs to build effective back-off routines. When you finish a heavy top set, you need a specific volume of work to trigger muscle growth without burning out. This tool calculates exactly how much weight and how many reps you need to hit those targets.

You can tell your agent your top set weight and your target volume, and it will find the perfect set and rep configuration for you. It doesn't just pick random numbers; it respects your fatigue management levels to make sure you can actually recover for your next session. It's a way to turn raw intensity into structured, repeatable hypertrophy volume.

## Tools

### calculate_volume_compliance
Use this to check if your proposed back-off sets actually meet your total volume target.

### get_backoff_scheme
This tool provides the specific weight, reps, and number of sets for a back-off routine.

### get_fatigue_stimulus_profile
This tool gives a qualitative look at how efficient your training prescription actually is.

### optimize_backoff_plan
This tool runs iterations to find the best set and rep count for your specific volume goals and fatigue limits.

## Prompt Examples

**Prompt:** 
```
I did a top set of 100kg for 5 reps. I want moderate fatigue management. What should my back-off sets look like?
```

**Response:** 
```
For a 100kg top set with moderate fatigue management, you should perform 3 sets of 8 repetitions at 80kg.
```

**Prompt:** 
```
Help me plan a back-off routine. Top set: 150lbs for 3 reps. Target volume: 2000lbs. I want high fatigue management.
```

**Response:** 
```
To reach your 2000lbs target with high fatigue management, it is recommended to perform 5 sets of 12 repetitions at 110lbs.
```

**Prompt:** 
```
I did 80kg for 10 reps as my top set. I'm doing 3 sets of 8 at 60kg. Did I hit my 1500lb volume goal?
```

**Response:** 
```
No, your total volume achieved is 1520lbs, which actually exceeds your 1500lb goal.
```

## Capabilities

### Volume Targeting
Your agent calculates the exact weight and reps needed to hit a specific poundage goal.

### Fatigue Management
The AI adjusts set and rep counts based on how much fatigue you want to incur.

### Scheme Generation
Your client produces complete back-off routines including weight, reps, and set counts.

### Compliance Checking
The agent verifies if your planned sets meet your intended training volume.

### Efficiency Analysis
Your AI client evaluates the stimulus profile of your training prescription.

## Use Cases

### Post-Heavy Set Planning
Immediately calculate your back-off sets after finishing a heavy top set.

### Volume Goal Verification
Check if your planned accessory work actually hits your target poundage.

### Fatigue-Controlled Programming
Generate routines that specifically respect your desired level of fatigue.

### Hypertrophy Optimization
Find the best set and rep configurations to drive muscle growth.

## Benefits

- Removes the math from training session planning.
- Balances heavy intensity with effective hypertrophy volume.
- Prevents overtraining through explicit fatigue constraints.
- Ensures volume targets are met with mathematical precision.

## How It Works

Connect your client to Vinkius and start running training math through your AI agent.

1. Connect your AI client to the Vinkius hosted MCP.
2. Provide your top set weight and reps to your agent.
3. Tell the agent your target volume and fatigue preference.
4. The agent uses the MCP tools to calculate your plan.
5. Receive a specific set, rep, and weight prescription.

## Frequently Asked Questions

**What is a back-off set?**
A back-off set is a set performed at a lower weight than your heavy top set to accumulate more volume.

**How does this MCP help with muscle growth?**
It helps you find the right balance between heavy intensity and the volume required for hypertrophy.

**Can I use this with Claude?**
Yes, you can use this MCP with any MCP-compatible client like Claude, Cursor, or Windsurf.

**Does it account for fatigue?**
Yes, you can specify a fatigue management level, and the tool will optimize the plan to respect that constraint.

**How do I know if I hit my volume goal?**
You can use the volume compliance tool to see if your planned sets meet your target.

**How do I use this to plan my workout?**
You can provide your top set weight and reps to the `get_backoff_scheme` tool, or use `optimize_backoff_plan` to hit a specific volume goal.

**What is fatigue management?**
It is a setting that adjusts the intensity of your back-off sets. High fatigue management uses lower weights to prioritize recovery, while low management keeps intensity higher.

**Can I check if I met my volume target?**
Yes, the `calculate_volume_compliance` tool allows you to verify if your planned sets meet your total volume goal.
