we’ve had a full size Thumper for twenty years and it can be a little rough… don’t get it close to your spine! To be honest it is a little too aggressive for my tastes.
We also have a collection of stuff like random 3’ foam roller, various wooden foot rollers, message sticks, and a TriggerPoint’s GRID 2.0 foam roller:
That GRID foam roller is my favorite. After rotator cuff surgery I had a frozen shoulder and went to the PT for over 6 months. Since I can’t go to a PT for every sore muscle, I pull out the GRID and a couple minutes later all is good.
