The Royal Lat Pull Down is great to strengthen the upper body - the back, arms, and chest. Lat pulldown exercises work the biceps, rhomboids, trapezius, rear deltoids, and the latissimus dorsi. Besides helping to strengthen the upper body, lat pulldown exercises also help to improve the stability of the lower back and the core. The Royal Lat Pull Down is made with commercial grade material, and is great for use at outdoor parks. It is meant to be used by those individuals who are 13 years of age and up, and comes with an instructional guide, so users will be instructed on how properly to use the equipment.
