Set foam rolling time per muscle group.
Foam rolling time is the product of muscle groups, passes and seconds per pass — a structure that makes it obvious why a thorough session runs to ten minutes rather than two. Thirty to sixty seconds per pass is the range most protocols use, and two passes per group allows one exploratory pass and one slower pass on the spots that need it. The weekly and monthly totals are what determine whether the habit is realistic.
Rolling session time
Session seconds = muscle groups x passes per group x seconds per pass; weekly minutes = session minutes x sessions per week
These figures are estimates based on population-average formulas and are intended for training and recreational planning only. They are not medical advice. Consult a qualified health professional before starting or changing an exercise programme, particularly if you have an existing medical condition.
Thirty to sixty seconds per pass is typical, with a second slower pass on tender areas. Much longer per area rarely adds benefit and eats the session.
It produces short-term range-of-motion gains without reducing strength, which makes it useful before training. Long-term flexibility comes from stretching and loaded range work.
Uncomfortable is expected; sharp pain is not. Avoid rolling directly over joints, bone and injuries.
