Thank you all! This is exactly what I was looking for.
I’ve started integrating YTAs for my shoulders as well as downward dog push ups, etc. I’m switching from back squats and leg extensions to blugarian split squats and Dumbbell/Barbell lunges. I’ve also started moving away from powerlifting/crossfit style lifting towards bodybuilding style as (to my understanding) it is better for tendon and ligament strengthening.
I have Becoming a Supple Leopard tucked away somewhere among my small library of fitness books. I’ll dust it off and start implementing their routine and see if that helps.
Definitely feel like I shouldn’t be having all these aches at 27 years old, but it is what it is and I’ve gotten better at tempering my enthusiasm, which was a problem and led to many injuries in my teens and early 20s.
