The Standing Dumbbell Row is a very functional exercise for targeting your back and shoulder muscles while also building core strength simultaneously. Given its 'bent over row' position, your body is forced to maintain balance while demonstrating good form on each repetition. This increases the work rate of your legs and abdominal muscles to hold the position, especially when holding heavier dumbbells. While the workout is great for building your upper back, it also recruits your lats, biceps, lower back, and deltoids as secondary muscles during the lift. Contracting all these muscles together contributes to burning a lot of calories when performing this exercise. A great routine for weight loss and firming up!
