Thank you, Nathan! Very helpful and along the lines I was thinking - especially the exhaustion approach. Also, as per recommendations from others, I'm thinking about using some manual soft tissue movement (rubbing, light percussion, and even shaking the tissue) before stretching to help it let go. And, may use bands to help traction joints while getting into stretches. "Big blog of goo" might be a bit too woo-woo for him (he is, as I heard someone say in Oz, a bloke's bloke). Will let you know how it goes!
