what does mobility look like?

Here's an example that works for me.

Knees over toes

Tib raise x20 + calf raise x20

Tib raise x20 + knees over toes calf raise x20

Tib raise x20 + Jefferson step 2x20

Mobilize spine

Bent over QL reaches 2x12 + upper isometric

Cat cow 2x10 + upper isometric 

Glute bridge (bridge progression) 3x50. Do not push until failure.

Stretches

Adductor + upper isometric

Hamstring + upper isometric

Hips

Downward dog into forward step

This is easy, repeatable, and offers movement to stiff joints. The upper isometric offers a way to flush blood into areas that were worked the day prior.
