Begin with a dynamic warm-up to prepare your body for the circuit. Focus on activating your core and engaging your glutes. During the circuit, maintain a steady pace and focus on proper form. For air squats, ensure your knees track over your toes and your hips reach full extension at the top of the movement. For toes to bars, aim for a controlled movement and avoid swinging. Modify with knee raises or hanging leg raises if necessary. During burpees, maintain a consistent pace and focus on a full range of motion, including a chest-to-ground push-up and a jump at the top. Wearing a weighted vest will increase the intensity of the workout, so listen to your body and modify as needed to maintain proper form and safety. After the circuit, cool down with stretching, particularly focusing on the legs, core, and upper body. Take time to properly recover and refuel your body with water and nutritious food.
