Bosu Ball Core Blast

Another ab workout post is here! My classic core workout doesn’t involve any materials, but this one is for mixing up the ab routine game. I love doing this bosu ball workout after some cardio, so I can really feel my core burn. Sometimes I even do my 12 minute ab workout after this for some serious soreness! Enjoy 🙂

#1 The Middle Crunch

Start by lying on the bosu ball with knees bent and your feet on the floor. To crunch, bring your shoulder blades off the ball and bring your right knee straight into your chest.

Repeat this crunch for 15 reps.

Then, hold your knee in and complete 15 mini crunches. Repeat on the other side.

#2 The Twist Crunch

Begin just like the previous move. Twist your upper body to the right and bring your right knee to your left elbow. Complete 15 reps, then 15 mini crunches. Repeat on the other side.

#3 The Bosu Plank

Flip the ball over so the firm side faces up. Place your hands on the flat surface and come up into a plank.

Hold normal plank for 30 seconds.

Then, bring your right leg up, foot flexed, and hold for 15 seconds. Repeat with the other leg.


If your abs are begging to be worked even harder, repeat this workout three times. Keep the plank the same. For the crunches, round 2 = 10 reps and round 3 = 5 reps.

If you completed this entire workout, your core is exceptional!
