This pole exercise is called The Triangle and has a super simple set up. Put three poles in a triangle shape and make sure it is lined up in the middle of the arena, on the centre line. When you stand in the middle of the bottom pole of the triangle, you should be lined up with A, C, B and E if you have letters in your arena. You could also set this up with the ¾ line if you want to practice your circles there instead of on the centre line.
