Starting a fitness journey can be overwhelming, but focusing on key components—strength training, cardio, and mobility—creates a solid foundation. Strength training helps build muscle, improve posture, and boost metabolism, while cardio enhances endurance and heart health. Beginners should start with bodyweight exercises like squats, lunges, and push-ups, alongside simple cardio activities like walking or cycling. Mobility and flexibility exercises prevent stiffness and improve movement quality, making workouts safer and more effective. A personal trainer can help structure a well-balanced routine that progresses gradually to avoid injuries and burnout.
