I can do about 2:36 when I tried it recently sitting at kitchen table, zero preparation besides few deep inhales/exhales.
I remember without any preparation in past I could do 50-70 seconds, so I was blown away by 2.5 minutes after many years, do those few deep inhales/exhales prior holding breath make that much difference?
I am not doing any sport or exercise, at best like <5mins per day, just walk everywhere and sit at computer most of the day.
