As I get older I find I need to have more stretching but I don't mean after a cool down and a lengthening of the muscles and release of Lactic Acid. I don't have a physical fitness background and don't know what to call it ... but something to add on at the end or do a 40 to 60min on a recovery day. Posture, lengthen and strengthen the "facia" and posture correction stuff. At soon to be ... yikes .. 62 I need to add this stuff in. And nobody cues like Cathe. Nobody. I was struck with an autoimmune disease over night at age 39 and Cathe keeps me strong, limber and motivated to do my best! I mean it!!!
