I am a second year vaulter, and my plant is in need of much work. I have been doing drills for several weeks now with very little progress, so I was wondering if any of you had any tips on drills and mental techniques to correct the plant. When I plant, my left arm generally collapses, my head looks up, and my hips immediately swing through, generally with the trail leg not very straight. I can still bend the pole and get in, but based only on runway speed. Here is a picture of my plant:
How do you get yourself to keep your hips back and move the pole forward with your arms? Thanks!
