About Marble Fitness
You can't fix what you can't see. Marble scores your physique from a single photo: body fat, muscle, proportion, and the shoulder-to-waist ratio that decides whether you read as built or just big. Then it shows you the version of yourself worth chasing, and hands you the plan to get there. A real score. Where you actually rank, broken down by what's holding you back. No vague pat on the back. It rates five muscle groups so you know exactly which ones are dragging the rest down. Your peak. A picture of the physique your frame is capable of. Same you, built out. The goal stops being some guy on Instagram and starts being you. A plan built around your weak points. Most programs spread effort evenly and hope. Marble loads the volume onto the muscles killing your score: shoulder width, lat width, a tighter waist. Sessions run 45 to 60 minutes and fit your equipment, your schedule, and whatever you're working around injury-wise. Numbers for the kitchen. A calorie and protein target set for your body and your goal, whether you're cutting, holding, or adding size. No food diary, no weighing rice. Four rules you'll actually stick to. Proof it's working. Log your lifts. Rescan whenever you want and watch the number move. The plan adjusts as you do. It's all built around one shape: broad shoulders, wide back, narrow waist. The V-taper reads as strong before you've said a word, and it's trainable on purpose. Start now.
