Anchor a resistance band at about chest height and stand facing the anchor with feet shoulder-width apart. Hold the band handle in one hand with arm extended. Pull the band toward your torso by bending your elbow and squeezing your shoulder blade toward your spine. Pause briefly at the end of the pull, then slowly extend your arm back to the starting position. Keep your core engaged and maintain an upright posture throughout.
Log your band standing single arm row sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
