Practicing balance on unstable surfaces like a slack block or slack line is beneficial.

“I like balance stuff. This is kind of a fun toy. This thing is fun to play with. This is a balance task in general. I like single leg pistol squats so I've been kind of playing around with single leg pistol squats on the unstable slack block with both legs. It's harder with my left leg. You can see the full slack line here which is the smallest slack line that I've ever built but it's better than nothing for now. More balance.”
