This MCP server provides specialized tools for strength athletes to measure Time Under Tension (TUT). By inputting repetition tempo (eccentric, pause, and concentric phases) and rep counts, users can use calculate_set_tut to find total duration, get_phase_distribution to see time allocation, and analyze_training_goal to determine if a set favors hypertrophy or strength. It also provides recovery guidance via recommend_rest_period based on training objectives and intensity.

I did 10 reps with a 3s eccentric, 1s pause, and 1s concentric tempo. What was my total TUT?

Your total time under tension for that set was 50 seconds.

Is a set with 60 seconds of TUT good for hypertrophy?

Yes, a 60-second TUT is generally well-suited for hypertrophy as it provides sufficient metabolic stress.

I'm training for strength at high intensity. How long should I rest?

For high-intensity strength training, a rest period of 180 seconds is recommended to allow for full ATP replenishment.

You can use the `calculate_set_tut` tool by providing the number of repetitions and the duration of the eccentric, pause, and concentric phases.
