Numerical wellness trends are all the rage on TikTok right now, and the instructional 6-6-6 walking challenge is the latest hype to liven up a humble stroll. There are various variations of the fitness challenge, but the rules are simple. One way to do the 6-6-6 involves walking for 60 minutes at both 6am and 6pm, with a 6-minute warm-up before you set out and a 6-minute cool-down when you come to the end of your walk. If that sounds like too much time and effort, a more manageable variation entails a 60 minute walk either at 6am or 6pm with a warm up and cool down either side. ‘Whichever version of the trend you try, the key here is the consistency and discipline to not miss a day and keep the momentum flowing,’ explains Kian Patel, founder of walking community All Terrain 95, (@allterrain95).
