It's been a long time, but I always thought it was easier to spend time on rollers than on a trainer. At least a little bit of your mind has to stay engaged keeping you centered. A lot of LBSs and bike clubs have winter group trainer sessions. Always more fun with company.


I also finally read the article and found that it doesn't define "moderate intensity" physical activity. The original study apparently is in next week's print edition of the JAMA, not online yet, and who knows if it's free anyway (I don't subscribe). But the CDC gives the following examples of "moderate" physical activity:

Walking briskly (3 miles per hour or faster, but not race-walking)
Water aerobics
Bicycling slower than 10 miles per hour
Tennis (doubles)
Ballroom dancing
General gardening

So I still think that a lot of ADLs rise to the intensity level they're calling for. "General gardening" is the only one they mention, but the way I do it anyway the "moderate to heavy housework" I mentioned is at least as intense as "general gardening" - sure it's harder pushing a rear tine tiller than a carpet shampooer, just for instance, but most people shampoo a much larger area than they till, and do it more often as well; as far as the lightest activities in the categories, dusting is at least done standing and picking up objects, while weeding is practically a seated meditation.
