During a real-life class or event you have accountability meaning you will push yourself further because you’ve got other people cheering you on, panting away with you orrrr you just don’t want to be the one in the class that gives up. You also get direct & immediate feedback, you can ask questions easily and you’ll be spotted nice and quickly if your technique is off. You’re waaaaay more focused because you’re not in your house full of screaming children, farting dogs or that heap of washing you promised yourself you would sort out this morning. And let’s not forget you’d be surrounded by other sweaty bodies, moving in sync.
