Dh's coworkers are doing a walking challenge, seeing who can get the most steps per day. Dh didn't join until mid-June, but since then he has been averaging 15K steps or more per day, sometimes a lot more. About half of the guys who started in January have over 1K miles walked so far. Anyway, because Dh had a liver test come back less than ideal and his triglycerides are high, he has taken this opportunity to get healthier. He has adjusted his eating habits and with the exercise, he has lost about 15 lb in the last month.
Because I don't want to be left out, I have increased my activity level, too! I don't enjoy walking, and I have never, ever had a pair of shoes that didn't leave blisters after walking many miles in a day, so I bike about 20 miles a day (trying to increase, but it is hard to find a route that increases mileage slowly instead of all at once). I, too, have adjusted my diet, trying to eat more fruits and veggies and less bread and potatoes. I even downloaded an app on my phone to track measurements and weight. I want my weight to be healthier (so, down), and I want my measurements to be healthier (bigger hip to waist ratio, meaning less abdominal fat).
Even though we aren't doing the same activities, it is nice to both be getting healthier. His group keeps him competitive with the other guys (they all post their steps from their phone app each day), and my charts and graphs keep me accountable, at least to myself. And we're cooking healthier meals for the whole family!
