That happened to me with heavy weight lifting, or pedal to the metal aerobics. But if what I am doing burns no more than 8-10 kc/minute, I am ok for daily. I can do shorter mini-sessions of much greater intensity, then row very easily for the rest of my mileage. Same with interleaving intense kettlebell swings with rel light heavyhands.
I want to get in 3000-4000 kc/week. I keep a 7 day moving sum to keep me tuned in. Sometimes I miss, sometimes I go over. Overall, I am runing a bit below goal, but this is a step-up from before and I am taking my time getting it grooved. A very long Sunday hike would allow this without daily work, but my arthritic hip would be killing me by the end, and I want to preserve that hip as best I can. I never feel it at all on the rower. So a daily combination anchored by C2 seems best for me. I will add a lifting session 1x/wk when do deadlifts, rows, and mil presses, when I get to 1000km on my C2, I think I can shoehorn what I need for this into my apt. Or keep it in my storage locker and do it down there.
I don't beleive any of this is harmfuil or unsustainable. My mother's father and mother ran an old fashioned subsistance farm on a quarter section, long before social security. They got whatever cash they need from tobacco. No electricty, no tractor or truck, a couple of plow horses, a well with a throw down bucket and a cistern with a hand pump in the kitchen no less, a wood lot and cooking and heating with wood-those were their modern conveniences. I doubt my grandfather lived a day that he didn't spend 4000 kc working. He was 5'10" and weighed maybe 145. He lived to 84, saw a doc only once when he got kicked while shoeing a horse, and worked the morning of the day he died. In other words, his final illness lasted only 45 seconds. I laugh at gurus wno warn against "chronic cardio". Before modcons, life was chronic cardio. And any man who has ever hunted without horses or winches and roads every ten feet, knows that hunting is intense, chronic cardio. So much for the fantasies about pleistocene men hanging around the camp sharpening spears then runing really really fast for 5 minutes to get their game. Don't think so amigos.
And to pull in the sittinng thread- they had a parlor, where they might sight for 2 hours on a Sunday if the preacher came calling, The rest of their sitting was done by Grandma at her sewing machine, or maybe snapping beans or shelling peas in the kitchen. Grandpa sat to eat his meals, otherwise he was up working or sleeping.
Only thing keeping me from much more work is too much laziness.
I imagine I could walk half a day without pain on a quality incline capable treadmill, since they are so much softer than concrete, but I really have no space for a good one, and they cost a lot too.
