Hello, welcome to our class. I am Penny Fawcett, and I'll be your fitness trainer. Today's class will focus on strengthening our core muscles, such as abs, back, chest, and arms. We'll start with some stretching exercises, then go on to bodyweight exercises like crunches, plank jacks, and push-ups. Let's get started and make sure to push yourself! If you have any questions, feel free to ask. Let's have a fun and productive session!
