6. Brown Rice

Brown rice is a slow-digesting carb that provides sustained energy for intense booty workouts. It’s also a source of B vitamins and magnesium. Fueling up with healthy carbohydrates like brown rice or quinoa a few hours before your workout can give you the energy to train harder, creating a stronger stimulus for muscle growth.
Interestingly, some studies also suggest that rice protein supplements can be just as effective as whey protein in promoting muscle gains when paired with a consistent strength training routine, Healthline notes.
