On day five of FitSugar's Countdown to the Oscars with Ellen and Bob, Bob shows us how to work our abs and core. You are going to need a light dumbbell (though you can do without it) and a physio ball.
Definitely try the balance exercise at the end because it is WAY harder than it looks!
Tomorrow is day six! Missed the previous days? Then check out all the Countdown to The Oscars posts this far.
