Fit vs Muscular vs Bodybuilder: How to Pick the Right Intensity
A short, honest guide to choosing between the three Muscle Editor intensity presets - and which one matches your starting frame.
Published February 15, 2026
Pick Fit if you want it to look real. Pick Muscular if you want it to look impressive. Pick Bodybuilder if you don’t care.
Most "this looks fake" comments come from picking Bodybuilder on a frame that can’t carry it. The intensity needs to match the input.
The work, step by step
- Fit - lean athletic. Subtle changes, believable result. Best for smaller starting frames or everyday social posts. The default for first-time users.
- Muscular - gym-strong. Clear six-pack, full pecs, defined arms. Reads as "obvious lifter" without going stage. The most-used preset overall.
- Bodybuilder - competition. Eight-pack, slabs of pec, vascular arms. Best for visualizing a 5-year ceiling, mock-up content, or just for laughs.
- Match intensity to your frame. Smaller frames look most natural on Fit. Mid-frames flatter Muscular. Larger frames can carry Bodybuilder.
- Run all three to compare. Generate Fit, Muscular, and Bodybuilder of the same photo. Use the credit on the comparison; it teaches you the model fast.
Common pitfalls
- Picking Bodybuilder for a six-month gym goal - you’ll discourage yourself.
- Using Fit when you actually want a "transformation" before/after.
- Forcing a level the photo can’t support (e.g. Bodybuilder under a baggy hoodie).
How Muscle Editor fits in
In Muscle Editor, intensity is per-edit, not per-account. You can run abs on Bodybuilder and chest on Fit if that’s what your frame needs. Most users find the right preset by their second render.
Frequently asked questions
Can I mix intensities across body parts?
Each body part renders together at one chosen intensity. Run separate edits if you want different intensities on different parts.
Which preset is most realistic?
Fit. It produces edits that pass casual inspection on most starting frames.
Which preset is most popular?
Muscular - it’s the "obvious lifter" look and the goal most users are training toward.
