Working out in the winter

Well, this is the Sacramento, Commiefornia area, so no snow.
I walk around my neighborhood, three times a day.
Each walk is one mile.
My pace usually takes me 18 minutes, and around the 2,200 steps mark.
And now i have also been taking my bike out, and peddling around, that i haven't been doing in quite some time.

Might i ad, that between April and October, last year, i lost 50 pounds of weight, off this old mans body, by upping my walking distance.
Started out at 230 pounds, and got down to 180 pounds, which i have been staying at, the past 10 weeks.
I'm now back at my Air Force weight 44 + years ago.
