When you’re pushing for PRs in the gym, there’s one variable that matters just as much as your sets and reps: fuel. You can follow the best program in the world, but if your nutrition isn’t dialed in, your progress will reflect that (along with your energy and recovery). 

Fortunately, nutrition-tracking apps have come a long way in the past few years, simplifying a previously tedious and painful process. Whether you want precise macro data, simple meal logging, or a fully guided diet strategy, these tools help you stay accountable and fuel your training the right way. 

Better yet, TrainHeroic’s Nutrition tool (available for Athlete Pro users on iOS), can pull your macro/calorie data from your nutrition app of choice directly into TrainHeroic, making it easy to see how your fueling links to your training load, readiness, and performance.
