To improve your flexibility and joint mobility (such as ankle mobility before a squat), there is no need to cause yourself pain with a foam roller. Massaging the area with a moderate intensity of discomfort (rated at 5/10) for approximately 60 seconds offers the exact same benefits as a very painful massage (9/10).

This statement is solidly supported by sports science research. A randomized controlled trial (RCT) conducted by Grabow et al. in 2017 compared different foam rolling pressures (ranging from light to very painful) and confirmed that intense force provides no additional flexibility gains compared to moderate pressure. Furthermore, a meta-analysis by Wiewelhove et al. (2019) highlights that the benefits of massage on mobility stem primarily from nervous system relaxation and improved stretch tolerance, rather than a physical change to the muscle structure. The practical advice from Squat University to target an discomfort level of 5/10 for 60 seconds is therefore perfectly validated. This approach avoids unnecessary pain while optimizing muscle preparation before exercise. There is no exaggeration here; it is a safe, effective, and body-respectful recommendation.
