@holistichealthbyfaith: Don't walk longer. Grab a timer. Japanese interval walking is a simple walking workout that alternates fast and easy minutes, and it has real research behind it from Shinshu University in Japan. If you already walk every day and want more fitness and leg strength out of the same 30 minutes, interval walking is an easy upgrade. It works on a treadmill or outside, and all you need is a timer. A great walking workout for women over 40 who want results without adding more time. #japaneseintervalwalking #intervalwalking #walkingworkout #morningwalk #walkingforfitness
