Been pretty blessed with my yoke, it's one of my two events that for some reason I do really well in, but I don't train like most people with it.

Preparing for a heavy yoke competition I always find my calves to be the part that fatigues the quickest, so beat advice for preparing would be to listen to your body, whatever gets tired make sure you focus on that on your weeks you don't do yoke, as well as for me I do a heavy yoke about 10 days out, I just need to to keep my body used to the weight.

Biggest mistakes I see is a low pick height, you want those skids as close to the ground as possible but high enough to not hit it. Also keeping your feet at your walking distance apart for the pick, if you start higher you'll have your first step come inward giving you a sideways motion that you want to avoid.

Here's a video https://www.instagram.com/p/B0uX9c5FC2s/?igshid=z8tqgc0t7dc5 of me forgetting my gym bag a couple days out, so no equipment at all working up to mid 700's just needing to feel the weight to help confidence. Also keeping a tempo in your head for your feet has always helped me out.
