thank you for your answer. I started with my shoulder / overhead position, as it’s my worst area.

I watched all the mwod pro videos on this topic (the 1-3min long ones) and identified all areas I need to work on.

T-Spine

Rib Mobilization

Lateral Seam

Posterior shoulder

Anterior compartment

I tried 8-10 exercises and every single one definitely helped. I’m doing all those exercises in 3 sessions (15 minutes) every day. Even though every exercise helps with my shoulder issue, if I understood you correctly, I should rather pick 2-3 exercises and do those multiple times a day for maybe a week or so and then move on to the next set of exercises? 

Thank you for your help!
