You're doing wicked awesome @lexikon082 :) I remember turning the big 35 lol and yes it does have a way of motivating us. So glad to see it translate into actifitastic awesomeness for you my friend <333 Yes I find fast/power walking to be quite effective and puts much less strain on my knees. Always a pleasure to chat with you my friend & happy to share the actifit journey as well. Cheers!
