Train like a ninja with our patented Slackers® Ninjaline® Intro Kit with seven hanging obstacles. Our NinjaLine® allows for versatility in moving the obstacles further apart as your skills improve as well as including obstacles that vary in skill level. Change the order of the obstacles to create endless patterns. Easy installation and take down means that you can take your training with you to the park, to a friend's house, or wherever you want to train. We use 30-inch-by-2-inch, 6,000-pound strength professional slackline webbing so the Ninjaline® can be used as slackline to help build your balance and agility. Our exclusive ratchet is steel reinforced and the handle has a comfort TPR rubberized grip. Fourteen extra-durable double-length sewn pockets allow you to space out the included obstacles for a more difficult workout or add more to your line. The included nylon rope knots mimic a ball grip, but are softer for an easier grip along the Ninjaline®. The two-piece 16-inch monkey bar holds are made of birch wood. It also features two steel gym rings with ABS-textured grips. They're great for using body weight to train and develop overall upper body strength and coordination. All obstacles include 6,000-pound steel hanging delta safety clips and use UV-resistant nylon ropes with safety buckle attachments. Look for the Ninjaline® logo for guaranteed quality and products that meets top safety standards. Ninjaline® products have been designed for great versatility.
