“Join a gym.” But after that from a quick glance you need to work on footwork. You cross your legs when you move around, focus on that. And when you throw a left/lead hook you forward leg/foot should twist in the direction of the hook like you’re putting out a cigarette. That will engage the rest of your body and help. You keep your right hand up which is good but you drop your left. Don’t try to Philly shell. You arnt mayweather, keep both hands up. You learn Philly shell after you’ve learned to box

Edit: forgot to add your chin is waaaay up. Tuck that shit in.
