3D muscle map: find exercises by muscle group

The 3D muscle map is an interactive body you can rotate and tap to browse exercises by muscle group — pick chest, back, shoulders, biceps, triceps, glutes, legs, calves or core, and see a list of exercises that train it, each linking straight to a full 3D demo with form and voice cues.

How to use the muscle map

Select a muscle from the chip list, or tap directly on the 3D body itself — the tool detects which region you tapped and highlights the matching muscle group. The model updates to show that muscle glowing on the body, and a list of exercises that train it appears alongside, ordered roughly by how commonly they're used. Tap a different muscle at any time to switch the view instantly, and use the rotate gesture or mouse drag to view the body from the front, side or back if you're not sure which region a muscle sits in.

Why a visual muscle map helps

Muscle names (like "rear delts" or "lats") aren't always obvious to a new lifter, and a printed anatomy chart is static and hard to browse by exercise. Seeing the muscle highlighted on a rotating 3D body, then immediately getting a list of matching exercises, closes the gap between "what is this muscle" and "how do I train it" in a single view — useful whether you're planning a session around a specific muscle group or just trying to understand what an exercise actually works.

Primary vs secondary muscles

Most exercises train one or two muscles as the main mover (primary) and several others as support (secondary) — a bench press, for example, has the chest as primary and the triceps and front shoulders as secondary. Exercise pages across this site show both, and the muscle map itself focuses on primary muscle matches so the exercise list for each muscle stays focused on the moves that train it most directly, rather than every exercise that touches it even slightly. Checking both the primary list for your target muscle and its secondary mentions on other exercise pages gives a fuller picture of total weekly volume for that muscle across your whole plan.

Which muscle groups to train together

The map is also a quick way to plan a session: pick a muscle, see its main exercises, then check a complementary muscle group for the rest of the session — chest pairs naturally with triceps, back with biceps, and legs are often trained as their own full session given how many muscles are involved (quads, hamstrings, glutes, calves). See how to choose a workout split for more on grouping muscles into a weekly structure, and the muscle group hub for written guides to each area.

Using the map to plan a session

If you know you want to train "legs" but aren't sure which specific exercises to pick, the muscle map lets you check quads, hamstrings, glutes and calves individually and build a balanced session from what each shows, rather than guessing from memory. Once you've picked exercises, add them to a session with the plan builder, or start them directly from any exercise page's "start set" button.

Muscle map for gym and home training

Exercises listed for each muscle include both gym and home options, so the map is equally useful whether you're standing in front of a full rack of equipment or working with only bodyweight and a resistance band. If a muscle's top exercises need equipment you don't have, scroll further down the list for bodyweight or minimal-equipment alternatives that still train the same muscle as a primary mover, and check the matching equipment hub for a fuller explanation of how to use whatever you do have on hand, whether that's a single kettlebell, a resistance band, or nothing but your own bodyweight.

Muscle map for beginners

If you're new to strength training and unfamiliar with muscle names, start by exploring the map before writing any plan — tap through chest, back, shoulders, biceps, triceps, glutes, legs, calves and core one at a time to build a mental picture of where each sits and which exercises come up most often for it. This short exploration pays off later when reading any exercise's primary and secondary muscle list, since the names will already be familiar rather than abstract.

Privacy

The 3D model and muscle data load and run entirely in your browser — nothing about which muscles or exercises you view is sent anywhere or stored on a server, so you can explore freely without an account or any tracking of your browsing.
