Proper form is crucial in any fitness regimen, and there’s no shortage of videos that can show you how to do exercises from squats to forearm curls. But the videos often contain a lot of extras—ads, instructor introductions, and talk about the history of the move—did you know that the deadlift was popularized by German strongman Herman Goerner in the 1920s?—when all you want is to know that what you’re doing isn’t going to break you.

MuscleWiki gives the tl;dr. Created by London-based Ryan Watson (Reddit user notanotherlifter), a self-described “serial website maker,” the project aims to simplify fitness using a basic body illustration, gifs and simple instructions.

Users can mouse over a muscle, and discover which exercises work that specific area. For instance, when you land on the trapezoid muscles, you’ll find a seconds-long demo on seated dumbbell shrugs and standing bar shrugs. There’s also a step-by-step written guide to the movements, as well as calorie and rep calculators.

“A few years ago, I was in the gym trying to figure out if my bench press form was correct,” says Watson, who has been fitness training for nine years and has competed in a bodybuilding show. “I did a quick search on my phone to try and check. I was very annoyed to find that I had to watch a 10 minute video of someone talking before I could check the form.”

The site, shared in Reddit’s Internet is Beautiful community, has gotten great feedback so far, but Watson says, “what you see is only a fraction of our vision.” The MuscleWiki team plans to add a female version, along with exercises modified for at-home workouts.
