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.
