15 lbs is evenly distributed across a weighted bar unlike the traditional barbell. Each bar can be unscrewed at the mid-point to make 2 "half bars; so you can get even more creative with your workouts! weighted Bars are made of solid steel and measure 46.5" Long x 1.625" Diameter. Each weighted bar has a thick, closed-cell foam handle grip that spans the entire length of the bar. Grip material is smooth, pliable, and hygienic since it won't absorb perspiration and can easily be cleaned. The weight is clearly marked at each end of the bar in lbs. There are 4 different poundages to choose from: 9, 12, 15, and 18 lbs. Perfect for core strength training, cardio and step workouts, and functional type training in groups or individually.
