My friend Mercedes is a genius! She has come up with a manufacturing method that allows her to make super high quality, lightweight technique plates. Right now, the only plates retailing weigh 3.75 kg, but she's going to put out a variety of light plates. If you need to teach basic technique with the barbell, these are the ultimate bang for your buck.
These plates hug the collar snugly and there is no wobble or fear of bending; you can add as many small iron plates as you need. Many of the less expensive 10 lb and under training plates bend and warp easily with even minimal use; the high end 2.5 kg and 5 kg training plates from Eleiko can run close to $300 per pair. Hitechplates give anyone the ability to train from the floor. And in my mind, that allows me to make barbell lifts from the floor a lifetime skill and activity for anyone looking to create and maintain good lifting mechanics, mobility and basic leg / torso strength. It doesn't have to be heavy to appropriate or beneficial. And they sure make teaching and learning the basics a whole lot more fun!
If you have any questions about these, feel free to drop me a line.
