Remind me ladies. Which is the most important? I walk 5 days a week averaging about 10 km per day (6 miles I think?). I walk from the train to work (15 mins about), on my 15 min break in the morning, about 45 mins on my lunch and back to the train after work (another 15 mins). I walk pretty fast (about 1.5 km/15 mins). Is this good enough for a pink sway or not enough?
