Interval walking isn't a fad—it's proven science
A randomized controlled trial of 246 middle-aged and older adults found that interval walking (3 min slow / 3 min fast) significantly outperformed continuous moderate walking. Results included 13% increase in leg strength, 8-9% boost in aerobic capacity, and reduced blood pressure.
Read the study →Sedentary middle-aged individuals who followed a 3-month interval walking program saw their peak aerobic capacity increase by 27% and systolic blood pressure drop 8 points. The protocol: just 4 days/week, ~30 minutes per session.
