Liftosaur

Liftosaur is a weightlifting tracker built around Liftoscript - a text-based language for describing training programs, including progressions, percentages, RPE, supersets, and multi-week blocks, etc.

This connector gives Claude access to your Liftosaur account so you can plan and adjust your training in conversation:

• Programs — Read and write programs in Liftoscript. Claude can transcribe a published program like 5/3/1 or GZCLP, or design one from scratch using a built-in guide. It can also make a targeted edit to the program you're currently running.
• Simulation — Run a program through a playground before saving it: complete sets, change weights, finish the workout, and see exactly what the progression scripts will prescribe next week.
• Analysis — Weekly sets per muscle group, strength vs. hypertrophy breakdown, and estimated session duration, so you can check a program is balanced before committing to it.
• History — Read your past workouts, add sessions you logged elsewhere, and correct mistakes.
• Setup — Manage custom exercises, gyms, available bars and plates, and per-exercise 1RMs and weight rounding, so prescribed weights match what you can actually load.
• Body metrics — Track bodyweight, body fat, and body measurements, and read sleep, calorie, and protein data imported from Apple Health or Health Connect, and correlate it with your workout performance.
