What is a bumper plate? 

A bumper plate is a weight plate for Olympic bars that is made almost entirely of rubber (with a steel or brass collar in the middle that accepts an Olympic bar).

Why bumper plates? 

The "end state" of the Olympic lifts is overhead or at the shoulder. Many lifters drop the weights from overhead. Since bumper plates are almost entirely rubber, being dumped from the shoulder or overhead will not damage the weights, bar, floor, bystanders, the lifter, etc...

Bumper plates are also great for garage gym use- the rubber construction is much quieter than traditional metal construction.

What exercises can I do with bumper plates?
  • Snatch
  • Clean and Jerk
  • Press
  • Thruster
  • Deadlift
  • Squat
  • Bench
  • Overhead lunge
  • And even more!
