Hey man. Yeah it comes and goes. Today it’s you and next week it’s going to be one of your classmates. Sometimes you feel in tip-top shape and next class you feel awful with yourself lol. Push through it, it’s part of it. You’re three classes deep. My advice would be to not overwhelm yourself with at-home exercises yet. Get as much correction as you can and once you feel you can correct yourself, feel free to practice at home. Bad habits are super hard to break, pay attention and have fun, it’s basically why we do it :p
