10-Minute Stability-Ball Ab Workout From Heather Robertson
Heather is here for another stability-ball workout, this time focussed on your abs. The routine features two rounds of five exercises completed for 45 seconds each. These are prayer crunches, ball passes, rollouts, cross crunches, and reverse crunches. One thing we love about Heather's videos is that they include music so you don't have to put on your own playlist!
