Structuring a complete workout should include warm up, cardio, strength training, flexibility, and cool down components. Warming up prepares your body for exercise, preventing strains and tears. Spend at least 5-10 minutes raising your heart rate with dynamic moves that mobilize joints, like arm circles, walking lunges, and side shuffles. Cooling down after a workout is equally important to slow your heart rate and allow muscles to transition out of exertion. This also reduces next day soreness and dizziness. Dedicate 5-10 minutes for light cardio and static stretching when finishing your session.
