Protein shakes are a popular way to support muscle recovery and growth before or after a workout. Consuming a protein shake before or after workout can help provide your body with the necessary fuel to power through your exercise routine. On the other hand, having a protein shake after your workout can help replenish your muscles and speed up recovery time. It's important to choose a protein shake that contains high-quality protein and fits your dietary preferences. Consulting with a nutritionist or personal trainer can help you determine the best approach for your fitness goals.
