Thanks for a cheer up!
Our goal right now is to make it a somewhat pleasurable habit, as both are not super good on discipline - but we do manage it. Tasty protein shake before we go, sauna after we finish, and a small indulgence after we're back home, and it seems to work well enough! Also, monthly payments in a gym are just big enough for us to feel we need to put this money to work, and regular enough so we'll likely be reminded often enough.
Currently going for two weeks only, but we're going every second day and the streak is all good.
