I run 4 days a week (4km per day), fast for two days (72 hours total) do two gym strength workouts, one sauna session, and two Zumba classes. I also do cold showers daily. Floating once a week, facial ferment therapy once a week.

And still, I feel like hell today (and it is only Friday morning)

I used to run half a marathon every Thursday in a fasted (36 hours) state, but now I can't, I became weak and frail. Aging gets us all!
