Best International Apps

Is it the David Beckham effect? We're not sure, but the Adrian James 6 Pack Abs Workout app ($1) is one of the top 40 best sellers in the UK's iTunes store.

Adrian James is a known fitness model who launched his own company, Six Pack Productions, to create this popular fitness app. Watch James demonstrate certain fitness moves and share sample meal plans. There is also a lite version that's free if you want to test it out.
