Questions for Korfist-Kerr Talks
Hi Everyone. Chris and I are recording a talk Thursday. Does anyone have any questions about hips? We've talked upper body, trunk, we're into the hips now! Let us know!

1. What is the latest news on the RPR app? 2. I have the same question as Matt Seki, how much training do you give specific hip muscles? 3. During in season practice, do you only use 1080 to develop acceleration and top speed? Or do you still use the 23 second drill, flys, etc?

Anything on implementing extreme ISOs? Or super slow eccentrics (up to 2 minutes) heard Dan Fichter talking about them on the podcast with The Gap

I would also like to know if Chris has ever and still does utilize extreme isometrics. Like the lunge, wall sit, RFE split squat.
