This is such a good point! We definitely need to do that. What would convince you? The CDC guidelines for exercise To maintain your weight: Work your way up to 150 minutes of moderate-intensity aerobic activity, 75 minutes of vigorous-intensity aerobic activity, or an equivalent mix of the two each week. Problem is most people aren't doing anywhere close to the CDC guidelines. What we're hearing from users is that they can't say they are too busy for a 7-minute workout...so they end up doing it. If you do 7 min a day for 7 days that's 49 minutes a week of exercise - which helps people build the habit and the confidence necessary to "work their way up" to the CDC's suggested guideline.

I think any reference to an authority is enough for people. Something like what you mention in your reply would be good to work in to the marketing material somewhere.
