This size massage therapy ball is good for EVERYTHING. They are the medium size and can be used both in or out of the tote. We recommend you collect all 3 sets of balls, but definitely start with these. Your shins, forearms, back and quads will thank you!
Love all the different sized therapy balls. I use them every night on my back as it is usually in pain since an injury over 15 years ago. Great for sore muscles as well. Couldn't recommend these enough!
