High intensity exercise is an important part of a healthy lifestyle. Walking is an often underestimated option that almost anybody can do. Recent studies of elderly walkers in Japan have watched the effects of casual-pace walking versus higher-paced aerobic walking. The results clearly highlighted a boost in fitness for those who walked at a high pace.
The study gives hope to people who have previously shied away from high intensity exercise that they are not conditioned yet to do, such as jogging or spin classes for example. The study had adults between age 44-78 do intervals of high intensity walking for 30 minutes 3 times per week for 5 months.
