We had a great time filming the latest Rockstar Health & Fitness episode with, The Charlies!! They are adorable, talented and it was fun spending time with them. It was also interesting learning about their Iceland homeland, where they are superstars. The healthy popcorn they prepared was delicious. In fact, I’ve made it at home several times. I was really happy that they choose one of my favorite core exercises: plank pose. We use plank a lot in yoga because it is such a powerful posture. The main benefits are that it tones the abdomen and strengthens the arms, wrists, legs and spine. Learn more benefits about plank, a healthy popcorn recipe and fun facts about Iceland in the new episode of Rockstar Health & Fitness.
