Different sized therapy balls can be used for different areas of the body. Here is what we recommend.
- 2.5" diameter - usually used for the feet
- 2.75" diameter - usually used for the spine, thighs, IT band
- 3.5" diameter - usually used for the neck, spine, IT band, hips, QL, glutes, calves, and all large muscle groups
Listen to your body and consult your physician to see what they suggest if you are having difficulty figuring out what the best size is for your needs.
