The [Return to Impact] classes were very informative. The exercises introduced at the Last class could be introduced in the 1st one and encourage people to start them right away so it would be easier for them to ask questions and make their own assessments throughout the series.
My tight hip flexor has maybe improved a bit. Definitely don't experience extreme hamstring pain like I used to. Just have twice slightly but I seem to have a better understanding of what to do to prevent and fix that.
