No size issue, they are usually petite, and not bothered by the buggy. They probably miss it if anything
My main fitness was walking, long distance and speedy rather than pottering around. It’s so hard with kids, they aren’t bad walkers for their age but can’t really stride fast enough or cover distance in a way that will make a proper dent on my fitness levels.
I’ve still got my double, I live in a hilly area. My husband works long hours and I just don’t have time otherwise. I’m thinking of each afternoon popping them in the buggy for a really brisk hilly 3-4 mile walk. With the double it’s not easy. I do other things, like cycle, but this is a super easy no prep way of actually sticking to something for fitness tat works.
I’m getting flabby, odd? If you saw me regularly would you think it was odd...? We do walk together, but as I said it’s just not going to keep me fit staying at their pace
