Tests have sound it to be 30% more efficient in getting shape and it does increase walking speed over 10% but still makes walking feel easier.
Ok, it does look stupid, but I don't think it is a problem for us, I have been doing that for some 10 years now and I really can't walk without them now, it is so much better, does same for walking as aeromodding does for a car, imo.
My technique differs a bit from what is seen from video, I don't squeeze at all and I brake with legs and push with arms to get more training to my stomach area and upper torso.
When I walk from hotel to work location it is usually only few minutes, but whole day feels lot better when I start it with that, so worth a try.
I would need to loose 30kg, that is a lot of lbs, so I can recommend it for those not so sporty too, had over year of break from this and gained some 20kg, shame on me, so now working to loose that extra again and it does feel great.
1km is as good as 1.3km of standard walking, so it is easy to get lot of training in small amount of time.
Is that 30% hypermiling by walking then?
