How To Do a Half Guard Lockdown Calf Slicer in BJJ

The half guard lockdown is a great BJJ position that secures half guard, preventing your opponent from passing while allowing you to work on submissions and sweeps. By simply wrapping your feet around your opponent’s shin, you can prevent their movement and they have to work on passing your lockdown before they can think about passing your half guard. That extra step gives you a chance to work on submissions from half guard lockdown.
