Does Foam Rolling actually make a difference, or is it overhyped?

Meta-analyses and systematic reviews of foam rolling and self-myofascial release consistently find modest short-term improvements in range of motion and some recovery-related performance parameters, without the flexibility loss sometimes associated with static stretching before exercise. Weighing the data: Foam Rolling looks an early-stage, lower-priority area for now — the evidence is only moderate (42/100), and its estimated impact (21/100) is on the lower end too.
