Begin with a dynamic warm-up to prepare your body for the circuit. Focus on activating your core, upper body, and leg muscles. During the circuit, maintain a steady pace and focus on proper form for each exercise. Take breaks as needed, but aim to complete all 23 reps of each exercise before moving on to the next. For air squats, ensure proper form with your knees tracking over your toes and your hips reaching below parallel. For push-ups, maintain a straight line from your head to your heels and lower your chest to the ground. In kettlebell swings, hinge at your hips and use your glutes and hamstrings to power the movement. For jumping lunges, maintain a stable core and land softly on your front foot before switching to the other leg. During sit-ups, keep your feet anchored and your core engaged. For box jumps, focus on landing softly and fully extending your hips at the top of the box. After completing the circuit, finish with a cooldown involving stretching, particularly focusing on the legs, hips, and shoulders.
