Muscle building may sound easy, but it's actually a lot of hard work. You'll have to go hard in the gym, and you'll also need to make sure that your nutrition is on point.
Brittany Linn, RD, CDN, a clinical nutrition coordinator at The Mount Sinai Hospital told POPSUGAR that you should eat one to three hours before exercising. Go for something that's high in carbs and lower in protein (so that you can digest it quicker) like fruit with yoghurt or toast with peanut butter and some banana.
According to Brittany, you should try and eat within 30 minutes after completing a workout. She recommends consuming something that is high in protein along with carbs in order to rebuild and replenish your muscles, for example, a protein, some brown rice, and vegetables or a protein shake.
Generally speaking, you should have a good balance of all the macronutrients — carbohydrates, fats, and proteins — as protein alone won't help you build muscle.
