The story behind Forma GYM

Forma GYM exists because the scariest part of a new gym is not the weight — it's the machine you don't know how to adjust.

Walk into any gym and you'll see the same scene: someone circling a machine, pretending to check their phone, trying to figure out where the seat goes and which handle to pull. Most people skip that machine, or use it wrong and feel it in their lower back the next day. The information exists, but it's scattered across videos with ads, forums, and apps that want an account and a subscription before they show you anything.

So I wrote the guide I wanted in my pocket: one card per machine, written clearly, with the setup, the movement, the common mistakes, and what changes as you get stronger. It's all inside the app, so it works in a basement gym with no signal. No account, no server, and nothing to cancel.

What it does

62 machines and equipment One detailed card per machine: what it trains, how to set it up, and how to perform the movement step by step.
Common mistakes, called out Each card lists the errors people make most often on that machine, so you can correct them before they cost you a rep — or a sore back.
Tips for your level Separate advice for beginners and advanced lifters. Set your level once and the App adapts its suggestions.
Search that finds it fast Search by machine name or by muscle group to find the right equipment in seconds, standing in the middle of the gym floor.
Suggested routines and dumbbells Routines suggested for your level and the time you have, plus a section of dumbbell exercises for when the machines are taken.
Nothing leaves your phone No servers, no cloud, no accounts, no analytics, no ads. Your preferences and your training log are saved only on your iPhone, and the App makes no network requests.
100% free. Forever.

Fitness guide, not a medical device Forma GYM provides general educational information about gym equipment and exercise technique. It does not replace a certified personal trainer, a physician, or a physical therapist, and it does not diagnose, treat, or monitor any medical condition. If you have an injury or a health condition, or you are pregnant, please talk to a licensed physician before starting or changing an exercise routine.
