Track Your Gym Diet — FreeWhy Gym-Goers Need a Better Nutrition Tracker
Generic calorie counters don't understand training. They don't adjust your macros on leg day vs rest day. They don't know that you need more carbs before a heavy session and more protein after. Macro Maxxing does.
Macro Maxxing was built for people who train. It automatically adjusts your daily macros based on your workout type and intensity, so your nutrition always matches your training.
Built for Every Training Style
Strength Training
Auto-adds protein and carbs on lifting days. Based on ISSN guidelines for resistance training nutrition.
Cardio & Endurance
Adjusts calories and carbs for cardio sessions. Whether it's running, cycling, or swimming — macros adapt.
HIIT & CrossFit
High-intensity sessions burn serious calories. Macro Maxxing accounts for the intensity and duration in your daily targets.
Yoga & Flexibility
Lower-impact sessions get appropriate adjustments. Not every day is a high-calorie training day.
Rest Days
Rest day macros stay at your baseline. Recovery is part of the plan, and your nutrition should reflect it.
Voice Workout Logging
Say 'upper body push, 60 minutes, heavy' and the AI logs your workout and adjusts your macros automatically.
