Old injuries from before I learned how to train. Post op check-in. All went well quite a bit of work done. All tendons around the shoulder fixed and the bicep tendon was removed and reattached. Labrum was completely shredded so it needed to be fixed. No new hardware needed. Will be a few months recovery with 6 weeks in the arm sling 24 hours a day but finally it's done.

Back at it with clients after the knee surgery. One more surgery to go shoulder and that should be it for now. I'll save the plastic surgery for next year.

Now I coach my clients to avoid it from day one:
👉 Form first
👉 Weight second
👉 Shoulders happy

Midweek flex with Rob Zombie screaming in my ears — and no, I’m never gonna stop.
Built like a beast, training like it’s still Monday.
