Sit on the floor with legs extended and loop a resistance band around your feet. Hold the band ends with an underhand (palms-up) grip and sit tall with core engaged. Pull the band toward your abdomen by bending your elbows and squeezing your shoulder blades together. Pause briefly, then slowly extend your arms back to the starting position with control. Keep your back straight and avoid leaning back throughout the movement.
Log your band seated underhand grip row sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
