Are we just trying too hard?  We don't have time in our every day lives to fit regular exercise in along with all the work we have to do.  So LifeSpan developed a "treadmill desk."  It's a desk that has a treadmill connected to it so that you can multitask both work and exercise at the same time.

From this review, done by Business Insider, if you put these in your office, most of your employees will not become more fit.  They will become more whiney.  Would you be willing to try it out?
