Wearing grey runners, a bright yellow Ivy Park crop top and matching bike shorts, Sam - who plays Jasmine Delaney on the Channel 7 show - looked fighting fit as she filmed the active scene.
Sam previously featured on the second season of The Bachelor and later starred in The Bachelorette before landing her own radio gig, Rove and Sam, on 2DayFM alongside veteran radio presenter Rove McManus.
Frost was cast as stunning Summer Bay nurse Jasmine Delaney in December 2017 and has quickly become a fan favourite.
