The internal martial arts can take many years to master, and without a good working knowledge of why things work in the form, the benefit is limited. However, as a general workout the Yang form isn't bad at all.
For a simpler workout the Russian physical fitness trainer Pavel has some good things to teach. Simple body weight exercises, no equipment really needed. Try browsing through a copy of The Naked Warrior, or Power to the People.

I have trained in several styles of Tai chi but for regular workouts simple bodyweight exercises are a great stress reliever for a student who spends a lot of time using their mind. Jogging, pushups, squats crunches that sort of thing is pretty mindless and feels good as a change of pace away from your desk.
