If I have time before the cut for sure (a little over 5 weeks).
I've been using joint products for years (inc N2JointRX when its been available). Fish oils as well daily (2g). That said (more so on the right side) there are range limitation issues aka 'frozen shoulder'. So, on bench days, you'd see me repping at lightening speed with a broomstick. Both in the bench type movement as well as a little back and forth (looks like a rotator cuff move).
On seated press days I start almost flat then move the back of the bench up two positions repping with a stick before warming up with the bar.
