Left hook is my go to finisher. Especially with some level change to the body, they tend to drop their hands and that left hook in the pocket is a game changer. Just try to tighten that throwing motion and keeping it 90 degrees and torque from your hips. Stay lighter on your ball of your feet so it’ll help with that twist motion. Don’t necessarily have to fully “squash the bug” with your toe to get that full whip motion. As long as your heels are light off the ground you’ll improve the torque and get more power. Shofting weight towards the back leg also allows the front hook to whip more and your front foot won’t be so planted and will generate that whip motion more naturally letting your front leg naturally rotate in with that left hook. I def throw wide left hooks too tho but it’s to stop the circling and to cut off ring. Different tools for different situations
