How this MCP server connects to your AI agent

One Rep Max Calculator estimates your true maximum weight capacity without needing to risk an actual max lift. It runs established scientific models—Epley, Brzycki, and Lander—against any set of weights and reps you input.

You can also calculate your current training load percentage to make sure every workout is hitting the right intensity zone.

What AI agents can do with One Rep Max Calculator Automation

Get brzycki estimate

Calculates your predicted 1RM using the well-known Brzycki formula.

Get epley estimate

Predicts your estimated 1RM using the Epley method, a popular standard in the industry.

Get lift intensity

Determines what percentage of your maximum strength you used for a given set.

+ 1 more capabilities included
Estimate 1RM

Calculates your predicted one-rep max using three distinct, proven strength formulas.

Assess Training Load

Built on the Model Context Protocol (MCP) for Claude, ChatGPT, Cursor, and more

The Model Context Protocol standardizes how applications expose capabilities to LLMs. Instead of operating in isolation, your AI gains direct access to external platforms, live data, and real-world actions through secure, standardized connections.

This connection provides 4 powerful capabilities that interface natively with Claude, ChatGPT, Cursor, and other compatible AI platforms. No middleware. No custom integration required.

The Guesswork of Training Intensity, Solved with Vinkius AI Gateway

Right now, figuring out if your workout was hard enough is guesswork. You lift a weight, you note the sets and reps, and then you have to stop and calculate what that means relative to your actual max—a calculation fraught with manual effort and formula confusion.

With this MCP, the process changes completely. Input your session data once, and your agent instantly returns multiple scientific estimates of your maximum strength. You get a precise, quantifiable metric without doing any math yourself.

Get Multiple 1RM Estimates with One Click

Before this MCP, you might have to consult three different textbooks or online calculators, each using a slightly different formula (Epley, Brzycki, Lander), and then manually choose which one was most accurate for your specific lift.

Now, simply passing your data through the tool automatically runs it against all three models. You don't pick an estimate; you get three objective numbers to analyze and build a stronger program around.

What your AI can actually do with this

You don't have to bust out on a max lift attempt just to know how strong you are. This MCP lets you predict your one-repetition maximum (1RM) safely and accurately. By connecting this tool through Vinkius, your agent takes your known workout data—like 'I lifted 100kg for 5 reps'—and runs it against multiple established formulas.

Instead of guessing or relying on memory, you get three different scientific estimates: one using the Epley method, another using Brzycki’s approach, and a third using Lander’s model. It also determines your training intensity percentage so you know exactly what kind of load you're working with. You just input the numbers; the MCP handles the complex math.

Questions you might have

How accurate is the One Rep Max Calculator using get_epley_estimate? +

It provides a scientifically recognized prediction, but remember it's an estimate. The Epley method is popular because it’s straightforward and reliable for general programming adjustments.

Do I need to know my actual 1RM before using get_brzycki_estimate? +

No, you don't. You only need the weight and reps you actually lifted in a given set; the tool calculates your estimated max from that data.

What is the difference between get_lift_intensity and 1RM prediction? +

Intensity measures load percentage (e.g., '85% of maximum effort'). 1RM tools predict the absolute weight number you can lift once.

Can I use this MCP for different types of lifts, like pulling movements? +

The models are general enough to handle various compound strength movements. Just ensure your input data (weight/reps) is consistent with the type of lift you're tracking.

Does get_lander_estimate use a different math than Epley? +

Yes, it uses a more complex statistical model that factors in multiple variables. This often provides a unique perspective compared to simpler ratio methods like the Epley formula.
