I'm sure running would work but it's fairly high impact and if you're skinny already then perhaps the high intensity cardio is not what would benifit you the most? Although anything to get your heart working and blood pumping will work! I'd strongly reccomend regular yoga as an antidote to the compressing forces of sitting at a chair all day. It's amazing how good I feel after just 20mins of stretches and body weight balances post chair sitting. There's loads of great instructors on codyapp.com, I reccomend checking out 'office therapy' and building up to some more intense ones
