This MCP server provides specialized strength training calculations to help athletes manage training volume. By using the get_backoff_scheme tool, you can determine the ideal weight and repetition ranges following a heavy top set. You can also use optimize_backoff_plan to automatically find the best set/rep configuration that hits your target volume while respecting your chosen fatigue management level. It is designed to bridge the gap between heavy intensity and effective hypertrophy volume.

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

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

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

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

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?

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

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.
