Dumbbell 21s: A Comprehensive Guide

The dumbbell 21s exercise is a highly effective workout targeting the upper arms, particularly the biceps and brachioradialis. This exercise involves a unique combination of repetitions that challenges both strength and endurance, making it a popular choice among fitness enthusiasts.

How to Perform Dumbbell 21s

To execute dumbbell 21s, begin by selecting an appropriate weight of dumbbells. Stand upright with your feet shoulder-width apart, holding the dumbbells at your sides. The movement is divided into three sections:

  1. Lower Half Curls: Curl the dumbbells from the bottom position up to the halfway mark (approximately 90 degrees) for 7 repetitions.
  2. Upper Half Curls: From the halfway mark to the top position, curl the dumbbells for another 7 repetitions.
  3. Full Range Curls: Finally, complete the remaining 7 repetitions by curling the dumbbells through the full range of motion.

Each segment of 7 repetitions builds strength and muscle endurance, making the dumbbell 21s a time-efficient exercise. While primarily known for bicep development, many variations exist, including tricep 21s dumbbell, dumbbell shoulder 21s, and dumbbell lateral raise 21s, allowing for a broader upper body workout.
