Remember that 7-min routine someone posted a few weeks back? (http://goo.gl/vwmYH). I've doing that every single day and I feel much better everyday, with more energy. Might sound silly for some that a routine that short would do anything, but it actually made a change. Anxiety is something that can block you from finishing projects and doing simple stuff, I totally agree with this article.
I like it a lot, it's a great basis for working out, though a few of the exercises are a bit advanced for beginners (in particular the tricep and rotating pushups should be gradually entered into to avoid injuring yourself). You can simplify and use some small weights to help work on some muscle groups before moving to the full workout.
I've rounded it out by including a few isometric exercises, some free-weights and balance exercises in between 7 minute rounds. You can get a real sweat from it if you take it seriously.
Seven minutes of effective exercise, done regularly, is miles better than being sedentary 100% of the time.
I've visited rehab centres before, and have seen elderly stroke victims doing little more than lifting their arms for exercise. When you've been bedridden for months, this sort of thing is real progress. So it is for the sedentary, when they start to get active in even "minor" ways, I'd say.
