This circuit will challenge your rectus abdominis (6-pack muscle), obliques, & low back for a well-rounded core workout! 

What You'll Need: A medicine ball and yoga mat. That's it! I used a 6-lb medicine ball, but use a weight that works for you.


  1. Side-to-Side Crunch 
  2. Crunch with Knee Pass
  3. Dead Bugs with Arms Overhead (move slowly & keep your abs engaged!)
  4. Dead Bugs with Arms Side-to-Side (move slowly & keep your abs engaged!)
  5. Side Plank (perform on the left & right)
  6. Back Extension with Med Ball Reach (be careful that the ball doesn't roll away!)

How To Do This: Perform 15 reps of each exercise. Hold the side plank for 30 seconds each side. After you've completed all 6 exercises, take a 60-second rest. Repeat for 2-3 total sets. 

Get ready for your abs to be a little sore tomorrow! I would love to see how you do with this one. Be sure to post to Insta using the hashtag #HMBgirl so I can see you conquer this workout!
