Im 34 and in the same boat. I try to hit the swimming pool 3 times a week at least, preferably during my “lunch hours” and it changes everything. Couldn’t go for the last 2 weeks and I feel like I’m 85. Not sure where it comes from.
I suppose it was technically possible while working in an office, but such a hassle. Always resulted in losing some workout time around the edges, too.
An hour in the morning and an hour-and-a-half around lunch have made it so much easier to stay sane, and provide nice cover to decline meetings by pointing to a calendar conflict.
