I noticed right when I finished the wide hurdler that the inside of the extended knee (around pes anserinus) got sore on exiting the stretch. It's the same soreness that I used to get a while ago when I was blindly fumbling around with middle splits by myself - it would come upon exiting the splits, and was sometimes there and sometimes not. Is the solution with the wide hurdler stretch to reduce the "width" of the hurdle position? And are there other factors I should alter?
Cheers.
