A new 20-minute dumbbell workout can be done at home to strengthen the upper body. It targets shoulders, back, biceps, chest, triceps, and core using body weight and free weights. The workout consists of a warm-up followed by two 10-minute rounds of exercises. Each round includes one-minute intervals with 45 seconds of work and 15 seconds of rest, featuring both bodyweight and dumbbell exercises. Experts recommend training the upper body two to three times a week for optimal strength and injury prevention.
