I've struggled with forward outside 3-turns since September. My problem is two-fold; I keep opening my hips, and my weight is not centered over the blade, but is shifted towards the toe pick instead, both of which cause me to put my free foot down.
Over my last two lessons I've finally been able to consistently complete right forward outside 3 turns, but I continue to struggle on the left side. Interestingly enough, the left side is my weaker side on forward crossovers, so I'm thinking I have issues with the left forward outside edge.
Which is why this weeks skating homework includes forward outside edges in addition to lunges, FO3's, and FI3's.
