Keith on Instagram: "PLANCHE EXERCISE This is one of my favorite exercises to work a planche and just great for your core and shoulders 1. Have your coach or a friend grab your feet (if you don’t have a friend isn’t telling a stranger “hey grab my feet” a great ice breaker?) 2. Then lean forward as far as you can then backwards opening shoulders 3. Notice how @owen_tong05 keeps pushing through his shoulders so his upper back is rounded. Also notice his lower back is straight! Give it a try! You
