i sit a lot and type for work which often gave me issues with my back, shoulders and wrists, so i asked my PT to give me a pre/post sitting stretch/relaxation sequence
i think it'll be useful for you. of course do be careful, choose what you are able to do, look up references on how to perform the moves if you're not sure, and stop if you feel sharp pain anywhere
Pre-Sitting Routine (5–10 minutes)
You'll need: resistance band, lacross ball (or equivalent), yoga mat
Cat-Cow Stretch (1 minute)
Start on hands and knees. Alternate between arching your back (Cow) and rounding it (Cat).
Loosens the spine and preps the body for sitting.
Hip Flexor Stretch (1 minute per side)
Kneel on one leg, with the other foot forward in a 90-degree angle.
Push hips gently forward to stretch the front of the hip.
Resistance Band Glute Activation (1 minute per side)
Place a band just above the knees, lie on your back, and perform glute bridges.
Focus on squeezing your glutes at the top of the movement.
