12 minute stability ball plank workoutGood Monday morning purely fit friends!

We had a fantastic weekend! Saturday was spent playing with our niece celebrating her birthday. Then Sunday was all about baby M and Lori!! We will share a recap of her baby shower later, but it was a lot of fun!

Lori and I have been proud of ourselves that the past 3 mornings we’ve worked out instead of sleeping in.  Each morning has been a different 12 minute bodyweight workout, and yep planking is in there too! And today we are sharing a new plank workout.

    Thank you SO much for this workout! I was looking for something that combined ab work and my stability ball AND would be safe for my 27-week pregnant belly. This is perfect!
