Once you connect to the HYBRD MCP, your AI agent will be able to: \n\n* Access and understand all your historical training data\n* Use that data to make workouts and training plans\n* Push those recommendations to your device (watch and/or phone) so you can execute the workouts\n\n**To get set up, just paste this into Claude / Muse / Instinct:** \n\nset up \u003chttps://hybrd.com/resources/mcp-setup/skill.md\u003e \\\n\\\nMillions of athletes already build training plans inside their favorite AI tool. But those tools have no access to wearable data, no memory from one session to the next, and no way to get a workout from the chat window onto an athlete's watch. HYBRD MCP closes that gap.\n\nThe first thing you should try with HYBRD MCP is to ask something like: \n\n* Across all my runs, when did I have the best ratio between grade adjusted pace and heart rate?\n* What was my most consistent phase ever? \n* What was the difference between my Napa Marathon prep and Boston Marathon prep?\n\nThen have it write you a training plan for your next goal: \n\n* Using the workouts I did most consistently, come up with a plan for Ironman California\n* Help me ramp back up to what I used to lift while maintaining my running volume\n* I’m traveling and will only have access to hotel gyms for a while, modify my current training plan\n\nHYBRD will write those workouts back to your wearable and phone, so you just have to click “start” and you’ll get guided through the plan\n\nYou can also use our companion mobile app to make tracking lifting easy, or track your runs using your phone’s GPS if you don’t have a smartwatch. \n\nHYBRD will manage your wearables connection, be a system of record for your training plan / completed workouts, and steer LLMs towards giving better fitness coaching\n\nThe experience gets especially magical with tools like Muse or Instinct, which can proactively check the local weather, block off time on your calendar, order the right fueling for you etc. \n\nSleep, recovery and nutrition data support are coming in the next few days. \n\nWe have a few thousand athletes on HYBRD so far, check out what they’re doing with it below: \n\n![uploaded image](/media/?type=post\u0026id=115915\u0026key=user_uploads/1315661/ba90bd48-3082-495a-97de-a5b4bcb80d5d)\n\n![uploaded image](/media/?type=post\u0026id=115915\u0026key=user_uploads/1315661/cd6fc55c-c6e3-4cd1-9adc-89e6e0429da4)\n\n![uploaded image](/media/?type=post\u0026id=115915\u0026key=user_uploads/1315661/df460c1b-8fe8-46bf-b60c-6b13ebbdebd8)\n\n![uploaded image](/media/?type=post\u0026id=115915\u0026key=user_uploads/1315661/1fa83022-70ae-49cd-8c18-613955ff486b)\n\n![uploaded image](/media/?type=post\u0026id=115915\u0026key=user_uploads/1315661/e99327d7-3a83-4373-8ce7-e1948cd1e8d3)\n\n![uploaded image](/media/?type=post\u0026id=115915\u0026key=user_uploads/1315661/9a2561b4-c0b7-4d60-822b-05f0184ee4df)\n\n","slug":"U9b-hybrd-turn-your-ai-agent-into-a-fitness-coach","created_at":"2026-09-17T20:41:16.655Z","updated_at":"2026-09-19T09:00:28.553Z","total_vote_count":5,"url":"https://www.ycombinator.com/launches/U9b-hybrd-turn-your-ai-agent-into-a-fitness-coach","share_image_url":"https://www.ycombinator.com/media/?type=post\u0026id=115915\u0026key=user_uploads/1315661/cd6fc55c-c6e3-4cd1-9adc-89e6e0429da4","company":{"id":30064,"name":"HYBRD","slug":"hybrd","url":"https://www.hybrd.com/","logo":"https://bookface-images.s3.amazonaws.com/small_logos/4d43a2e4ad2a1d85682aa3ad5a84240ff8cd7dca.png","batch":"Fall 2024","industry":"Consumer","tags":["Health Tech","Consumer","Fitness","Digital Health","AI"],"search_path":"https://bookface.ycombinator.com/company/30064"}}
