My thing is lower body from outdoor running; quads, lower legs and the calves in particular
Did see monthly sports physio for a year (work discount) tho last appt was April as think at a stage of only needing the occasional deep tissue session. Foam roller supplemented physio / also physio recc
Roller is fine everywhere except calves!! Physio fingers can get in deeper as rolling can feel like "mashing" surface without getting inside.
Spiky ball better than tennis ball tho find them better for say your feet or quads as again does not get deep inside my calves
Atm am browsing Amazon for physio tools that have an edge or point to see if that gets in deep where roller misses those spots
