A deadlift is a strength training exercise that targets multiple muscle groups, primarily the hamstrings, glutes, and lower back. It involves lifting a weighted barbell or dumbbells from the ground to hip level while maintaining a straight back and engaged core. This movement helps improve overall strength, posture, and athletic performance. To perform a deadlift, stand with your feet shoulder-width apart, grip the barbell just outside your knees, and keep your back flat. As you lift, push through your heels and extend your hips and knees simultaneously. Proper form is crucial to prevent injury and maximize effectiveness.
