This Skill addresses the tedious process fitness enthusiasts face when manually entering training plans—whether on paper or in digital formats—into the Hevy app, requiring them to input each exercise, sets, weights, and other details one by one. By leveraging Hevy's API, it allows users to describe their training plan in conversation or upload it directly, enabling AI to automatically parse the content and generate a workout schedule that syncs seamlessly to their Hevy account, eliminating repetitive manual entry.
Usage is straightforward. After installing the Skill, users simply describe their training plan in Claude (e.g., “Help me create an upper-body strength workout with squats, bench press, and deadlifts”). The AI then invokes the tool, guiding the user to confirm details or directly create the corresponding Hevy workout—all without leaving the chat interface.
It is ideal for fitness enthusiasts, athletes, or strength coaches who maintain regular workout routines and use the Hevy app to log their training data. The efficiency gains are particularly significant for users who frequently adjust or create new training plans.
Before use, ensure you have a Hevy account and know how to obtain an API key. Since the Skill relies on Hevy's official API, its capabilities are limited by what the API supports—for instance, it may not handle highly complex custom workout templates. We recommend starting with a simple training plan during initial use to familiarize yourself with the workflow before moving on to more complex routines.
Key Features
Unlike general fitness guidance or plan-generation Skills, this tool deeply integrates with Hevy's official API, enabling “one-click creation and syncing” of workout plans. It directly writes AI-generated plans into the user's actual Hevy account, creating a seamless closed loop from planning to logging—rather than merely providing text-based suggestions.
Limitations
It only supports integration with the Hevy app and cannot be used with other fitness tracking platforms (e.g., Strong, Keep).
FAQ
How do I obtain a Hevy API key?
You need to log into Hevy's web version settings page and generate a dedicated key in the Developer or API options section.
Can I modify a workout that has already been synced to Hevy?
Currently, this Skill focuses primarily on creating new workouts. For modifying or deleting existing workouts, it is recommended to perform those actions directly within the Hevy app.
