I only do two exercise classes a week; do I need a protein supplement? #QoW
Protein will help your muscles to recover, whether you’re working out six days a week or if you’re a casual class goer – the results are the same. If you’re a casual exerciser, you probably don’t need to the thinking about Creatine or BCAAs, but protein will be useful for your recovery.
You also need to consider your diet. If you're vegetarian or vegan and feel like you struggle to get enough protein from your food, you may want to consider a supplement whether you exercise or not.
