Foam rolling

Foam rolling is a form of self-myofascial release (SMR) in which the client rolls a muscle over a foam cylinder using body weight for pressure.^{1International Sports Sciences Association, Bodybuilding, p. 298.} It’s an inexpensive substitute for massage: the client places the roller between the floor and the target muscle, rolls slowly and stops on tender spots.^{1International Sports Sciences Association, Bodybuilding, p. 298.} ACSM reports that it can increase range of motion, reduce pain in the rolled muscle and the same muscle on the other side, and ease delayed onset muscle soreness (DOMS).^{2Ozemek et al., ACSM’s Guidelines for Exercise Testing and Prescription, 12th ed., p. 371.}

In practice

• Hold on a tender spot for 30 to 90 seconds, until discomfort drops by about half, then move along the muscle.^{3International Sports Sciences Association, Strength and Conditioning, p. 251.}
• More body weight on the roller raises the intensity; less lowers it.^{1International Sports Sciences Association, Bodybuilding, p. 298.}
• ISSA’s cool-down template uses a single pass per area, 1 to 2 minutes per spot and 30 to 45 seconds on tender spots, covering hamstrings and calves, glutes, quads and hip flexors, adductors, lower back and lats.^{4International Sports Sciences Association, Bodybuilding, p. 300.}

Where sources differ

The ISSA texts explain the effect through autogenic inhibition and the release of adhesions and knots in the tissue.^{3International Sports Sciences Association, Strength and Conditioning, p. 251.},^{1International Sports Sciences Association, Bodybuilding, p. 298.} ACSM cites a study in which sham rolling, the same movements without pressure on the muscle, increased range of motion about as much as real foam rolling.^{2Ozemek et al., ACSM’s Guidelines for Exercise Testing and Prescription, 12th ed., p. 371.}

For warm-ups, ISSA’s 2019 bodybuilding text warns that SMR may limit maximal force and power, like static stretching, while noting that no direct studies existed.^{4International Sports Sciences Association, Bodybuilding, p. 300.} ACSM’s 2026 guidelines report that foam rolling, unlike long static stretching, doesn’t impair later performance.^{2Ozemek et al., ACSM’s Guidelines for Exercise Testing and Prescription, 12th ed., p. 371.}
