Chizzl AI

Scan your physique. Get your plan. Track every rep.

Chizzl turns three photos into an honest read on where you stand. It provides a physique rating, a body-fat range, and identifies the muscle groups holding you back. It then builds the training plan to help you improve.

BODY SCAN Upload front, side, and back photos. Get an AI physique estimate with a rating out of 100, a body-fat range, strengths, weak points, and recommendations on what to train next. You can log EVERY workout you do for absolutely free!

TRAINING THAT ADAPTS Generate a weekly split built around your goal, experience, equipment, and injuries. You can also build your own plan. Chizzl includes 325+ exercises, per-side logging for single-arm work, and automatically saves every set as you train.

SEE YOUR PROGRESS A 3D muscle map lights up with the volume you've actually put in. Track weekly volume, streaks, personal records, and estimated 1RMs. Climb from Bronze to Platinum across 15 strength achievements.
