We all know that walking is good for us, both physically and mentally, but the Japanese believe they have an even better way to boost the positive results of walking. Originally introduced in 2007, an interval walking exercise routine called 3-3 walking has been making the rounds on social media. The exercise involves walking for 30 minutes, alternating between 3 minutes of fast-paced walking and 3 minutes of slower steps. Though the method is simple enough, it delivers a host of benefits, including lower blood pressure, greater leg strength, and overall better physical fitness. There’s a psychological appeal, too. Interval walking enables you to feel like you’re competing against yourself as you get faster and ratchet up your intensity level. People like numbers because they give walkers a tangible goal, which can propel their desire to work out. You don’t even have to aim for a 30-minute workout. Whatever feels comfortable for you is what you should do in the beginning. You can even use music to help you. Most songs are about 3 minutes long, so they’re a good way of timing your exercise. If you struggle with balance, use walking poles or a hiking stick to give you an extra set of so-called “legs.”
