Turn Claude into a Personal Fitness Coach

aitrendz_xyz · x · 2026-07-16

This post shares a prompt template that turns Claude into a "personal coach." By simply inputting age, weight/body fat goals, available equipment, training days per week, session duration, injury limits, and fitness level, Claude generates a 12-week training plan. This includes weekly schedules, exercises, sets, reps, and rest periods.

The author emphasizes that this isn't generic fitness advice, but a customized plan based on real-world constraints. The prompt also requires the model to explain the underlying training logic, helping users understand exactly why the plan is designed that way.
