What is dumbbell bent arm pullover?

A dumbbell bent arm pullover is an exercise that primarily targets the back and chest muscles, particularly the latissimus dorsi, triceps, and pectoral muscles. It involves lying on a bench holding a dumbbell with both hands and lowering the weight behind the head towards the floor while keeping the arms bent. Then, the weight is lifted back up to the starting position, being careful to keep the elbows slightly bent to avoid putting pressure on the joints. This exercise is beneficial for improving upper body strength, flexibility, and posture. It can also help to stretch the chest and improve breathing by expanding the ribcage.
