That sounds undesirable. I go 6 days/wk for 30-45min. I love the benefits of working out, but it's more of a mental break for me. I listen to Mixergy, learn a thing or two, and reset myself. I spend 12+ hours a day at the computer. The least I could do is workout for 30min.

The 7-minute workout is better than nothing, but I wouldn't look at it as a go-to strategy.

I guess it really depends on your perspective. I've always worked out, so I enjoy it. But for some it's an inconvenience. It just like food between my wife and I. She likes food variety and it's an experience for her. I just eat so I don't die and can (and do) eat the same thing every day.
