Up until recently we've been taking very little exercise possibly because we're out an about a lot and also perhaps because that's just an excuse. But recently we've been going for long, fairly energetic walks in the mornings before it gets too hot. I also carry a 1Kg weight in both hands to increase the strength in my arms by flexing up and down as I walk.
Adri uses the Pacer app on her phone and my Samsung Watch 3 monitors my walking and I've set the daily target to 7000 steps which is about 6Kms, so these are handy technologies that at least give you daily targets.
I used to be much fitter when I had a bicycle but I sold it a couple of years ago because I was hardly using it. I regret that now because I prefer cycling to walking.
Jogging? Forget it.
