J2 & K2 - Front Chin
Machine of the Month - J2/K2
Keep Your Back and Arms Strong with the J2 and K2
The J2/K2, or front chin, isolates and strengthens the latissimus dorsi and lower trapezius muscles in the upper back as well as the biceps muscles of the arms.
The front chin is a multi-joint exercise that focusses on lowering the body in a controlled movement. The J2 and K2 exercises use similar muscles to the C7 exercise and can help to improve posture and reduce shoulder pain.
The K2 uses the same movement as the J2, however it is performed on our K-tower and is supported by weights. This makes the K2 a great starter exercise for those working up to the J2.
Important Technique Points
- Be sure to keep your shoulders down throughout the exercise
- When you lower your body, be sure to keep the body stable and avoid swinging from side to side
- Be sure to keep your hips extended and your body in a straight line
If you would like to add the J2 or K2 to your training program, be sure to talk to an Exercise Scientist.
