Last monday, Mac Wilkins had two 1 hour webinars on discus throwing (Coach Mac has clips from these on his youtube channel). Seeing him in the snapshot reminded me of the answer (which isn't in the clips currently posted). Mac said you can't pick up your right leg if there's any weight on it, simple physics but true! So the answer is to shift weight to the left foot faster and with more precision to get on balance.
Then you have to ask yourself, what are we doing with the legs at the back of the circle? You're creating torque, force cross lever arm as my frosh mechanics professor would say. This is maximized when the force is 90 degrees to the line between the feet, the lever arm here. 12 o'clock is perpendicular to 9 o'clock, right on there.
Those videos with the coaches including Alekna's coach Mo are really eye opening. I laughed when Coach Mo said Alekna doesn't think about any of that when he drives into the circle. Makes me rethink that everything we see on competition video isn't intentional! You are definitely paying attention and I see a future biomechanical engineer.
Right foot kicks straight ahead, keeping the hips opened
From what I've seen and tried the hip and knee move forward and the right foot seems to just go along for the ride. You can really feel the separation in the knees when thinking of the hip moving forward first instead of driving to the left.
