What is FuelPhysique?
FuelPhysique is a personalized fitness platform that combines AI-powered workout planning, nutrition planning, a real-time workout tracker, and progress tracking — all in one place. Whether you're bulking, cutting, or maintaining, FuelPhysique adapts to your goals.
Is FuelPhysique free to use?
Yes — FuelPhysique has a free tier that includes access to the workout builder, nutrition builder, and workout tracker. A Pro subscription unlocks additional features such as unlimited plan generation, advanced analytics, and priority AI responses. See our
Plans page for details.
How does the AI Coach work?
The AI Coach is a conversational assistant trained to answer questions about fitness, nutrition, and training strategy. You can ask it anything — from how to improve your squat form to how to structure a cutting diet. It uses the context of your Athlete Core profile to give personalized, relevant answers.
What is the Athlete Core?
The Athlete Core is your personal profile — it includes your age, gender, height, weight, fitness level, goals, dietary preferences, and any limitations. This information is used to make your workout and nutrition plans as accurate and personalized as possible. You can update it at any time from Settings.
How does the Workout Builder work?
The Workout Builder walks you through a step-by-step wizard: you choose your goal (build muscle, lose fat, maintain performance, etc.), training style, equipment available, schedule, and priorities. Based on your answers, a full workout program is generated with exercises, sets, reps, and rest times — ready to follow immediately.
How does the Nutrition Builder work?
Similar to the Workout Builder, the Nutrition Builder collects your goal, body measurements, activity level, food preferences, dietary restrictions, and any relevant medical conditions. It then generates a personalized daily nutrition plan with calorie targets, macro breakdowns, and meal structure suggestions.
What is the Workout Tracker?
The Workout Tracker is a real-time tool for logging your workouts as you do them. It shows you one set at a time, lets you select your weight, logs your reps and RPE, and includes a configurable rest timer. All completed workouts are saved to your history and used to populate your progress charts.
What if I missed a workout and didn't track it in real time?
You can use the
Log Past Workout feature. It uses the same step-by-step interface as the Workout Tracker, lets you enter the weights and reps for each set, and saves the session to your history so your progress charts remain accurate.
How does progress photo comparison work?
On the
Progress page, you can upload front, side, and back photos with a date stamp. Over time, you can select any two dates and compare your photos side by side — useful for tracking body composition changes between a bulk and a cut, for example.
Is the AI Coach's advice medical advice?
No. FuelPhysique is a fitness and wellness tool, not a medical service. The AI Coach and nutrition plans are for general informational purposes only and are not a substitute for advice from a licensed physician, registered dietitian, or other qualified healthcare provider. Always consult a professional before making significant changes to your diet or exercise routine, especially if you have a medical condition.
Can I use FuelPhysique if I'm under 18?
Users between the ages of 15 and 17 can use FuelPhysique in Youth Mode, which requires acknowledgement of parental or guardian consent. Plans generated for users under 18 are tailored to support healthy growth and are not weight-loss treatments. Users under 15 may not create an account.
How do I cancel my subscription?
You can manage or cancel your subscription at any time from the
Settings page under "Billing". Your access to Pro features continues until the end of the current billing period. See our
Subscription Policy for full details.
