Why does this workout emphasize shoulders exercises?

Because shoulders strength is foundational. It supports everything from posture and balance to injury prevention and daily movement quality. Danielle Harrison programs shoulders-focused work into this session because it's the area most women lose strength in first during their 30s and 40s. The exercises here aren't random — they build on each other.

Can I do this workout if I have joint pain or stiffness?

Start with the modifications Danielle Harrison shows and see how your body responds. Many of the exercises in this session can be scaled — lower range of motion, lighter load, slower tempo. Joint stiffness in your 30s and 40s often improves with consistent movement, not avoidance. That said, sharp pain during any exercise means stop. Pain is information, not a challenge to push through.
