Dr. Muscle

Dr. Muscle is a weight training app that works as an automated personal trainer. It builds a program around the user's goals, equipment and experience, then adjusts every session in real time, raising or lowering loads, reps and volume from logged performance so progression keeps moving without the user having to plan anything. It is aimed at lifters who want a structured hypertrophy or strength program but do not want to design one. The app applies progressive overload and daily undulating periodization, schedules deloads, estimates one rep maximums, swaps exercises when equipment is unavailable, and supports multiple workout profiles for training at home, in a gym or while traveling. Mobility sessions, an Apple Watch companion and iOS and Android apps are included, and the developers publish release notes for each update. It was built by Carl Juneau, PhD, an exercise scientist, and the company runs a blog of evidence based training and nutrition articles alongside the app. The app starts with a free trial. The regular subscription is $29.99 a month. An annual subscription is $239.88 a year, which the company presents as the equivalent of $19.99 a month, and it renews at that annual rate. The upgrade page bundles a digital book on hypertrophy and a set of supplementary training, nutrition and cardio guides with the annual plan, and states that those materials are kept even if the subscription is later canceled. One thing worth noting is that the home page doubles as the company blog, so the app itself is reached through the trial signup rather than a conventional product page.
