I've been in the strength training game for over 40 years and coached weightlifting for 16 years. I've been in a lot of gyms and used every kind of equipment you can imagine. I've used about every kind of bumper plate made for training: Eleiko, Mavrick, Usaka, Werk San, Udaholm, York, RB, you name it. All have their advantages and disadvantages. But I have to say that these new Vulcan Strength Training Systems training bumpers are the best balance of everything I'd want in a training bumper. They have bright color for easy ID, very low bounce, and, as a longtime coach may worry about hearing loss, low noise. The tens are about as perfect as you could expect. They are thicker than any comp tens I've seen, so they don't warp and bounce sideways. The tens are not as thick as some training bumpers, but they don't bounce as high. When a new lifter is learning to control the bar drop, this can save shins on the next platfrom. I cannot speak to durability yet, as these are a new product, but I see nothing about them that would suggest they'll have a shorter training life than most good training bumpers. But for the price (pretty damn affordable!) I'm willing to take what little risk there is. I'd be comfortable outfitting a new gym with nothing but these bumpers. They're a budget stretcher and better than anything I've seen, down to the detail of the deep chamfer at the edge that makes picking up heavy plates from the floor much easier. I'm going to do my best to fill Rubber City Weightlifting with these plates.
