High Intensity Interval Training (H.I.T.T.) may have the same benefits as running and is a more efficient use of time: http://well.blogs.nytimes.com/2013/05/09/the-scientific-7-minute-workout/
Read the linked journal article.
Don't do HITT with low available glucose (blood and liver); your body will eat through what's present quickly, won't have enough time to prepare more, and will break down skeletal muscles for energy instead. I doubt this should prove problematic, but omitting this caveat is simply irresponsible.
Thanks! The 7-minute workout sounds reasonable and I might consider adding elements of it into my 4-minute abs workout I have already. It wouldn't replace running altogether since 1) I enjoy running, so it is not time lost and 2) I'm training for 5k cross country races.
