Desk workouts

Is it really possible to have fun at work? Fun and work are two things that contrast with each other! Work is nothing but a place of low energy, headache, and pain. In other words, work is no place for fun.
But what if I tell you that all it takes is just 10 minutes to enjoy work? Yes, 10 minutes.  10 easy minutes for a mild workout that you can do at your desk. No gym needed, no equipment needed! Just you and your desk!
