If you have searched Hevy AI recently, you are not alone. Thousands of lifters are curious whether their favorite workout tracker has finally gotten a real AI upgrade and whether it is worth using. The short answer is that Hevy now has an AI feature called HevyGPT, and it is a genuinely clever idea. But there is an important ceiling to what it can do, which is exactly where Proxima picks up. What is HevyGPT?HevyGPT is a custom GPT that Hevy built on top of OpenAI ChatGPT platform. The idea is straightforward. You open ChatGPT, describe what kind of program you want, and then ask it to save the program directly to your Hevy profile. The routines appear in a folder inside your Hevy app, ready to log.It is a smart integration. Hevy is already the gold standard for workout logging, and offloading program generation to ChatGPT means users get a conversational experience without Hevy having to build their own AI from scratch. To use it you will need a Hevy account, a ChatGPT Plus subscription, and Hevy Pro if you want to import more than four routines. There are also some notable limitations worth knowing about. It only works in the ChatGPT browser app on Android due to OpenAI platform restrictions. The exercise library is capped at around 100 exercises to keep the AI API calls stable. It can only create routines and cannot edit or delete existing ones. And the AI has no awareness of your training history, current fatigue, or past performance. In other words, HevyGPT is a program generator. You describe what you want, it builds something that looks reasonable, and you take it from there. It will not adapt as you train. What is Proxima? Proxima is a standalone AI fitness platform built specifically around one goal: generating science-backed, periodized training programs through a conversational AI agent. Where HevyGPT borrows ChatGPT general intelligence and points it at fitness, Proxima AI is purpose-built for programming. It understands periodization, progressive overload, training splits, and exercise selection at a deeper level. You chat with the agent, tell it your goals, equipment, training history, and schedule, and it builds a full multi-week program with proper structure rather than just a flat list of exercises. Proxima also integrates directly with Hevy, meaning you can build your program in Proxima and track it in Hevy, giving you the best of both tools. Which one should you use? Use HevyGPT if you are already a Hevy power user, you have ChatGPT Plus, and you want a quick way to generate a program without leaving the Hevy ecosystem. It is convenient and surprisingly capable for straightforward requests. Use Proxima if you want a program that is actually periodized, adapted to your goals, and built with the kind of structure you would expect from a knowledgeable coach. Proxima is not bolted onto a general-purpose chatbot. It is designed from the ground up to build training programs, which shows in the quality of what it produces. If you are serious about your training, the combination of Proxima for programming and Hevy for tracking is genuinely hard to beat, and since they integrate, you do not have to choose. The bottom line HevyGPT is a clever feature that shows Hevy is paying attention to where fitness software is heading. For casual lifters who want a quick AI-generated routine, it works well. But it is constrained by its dependence on a general-purpose AI with no fitness-specific memory or periodization logic. Proxima was built to solve exactly that problem. If you have been searching for a smarter way to program your training, it is worth trying, especially given that it connects directly to Hevy, the app you are probably already using to log.
