Check out your power with these re-formable Breaker Boards. Practice your breaking, and use them over and over again.
They are padded on both sides for extra protection.
The colours indicate increasing levels of difficulty.
The Yellow board is equivalent to a pine board of 0.25" thickness - blue boards 0.5", red 0.75", and black 1.0" thick.
Please note: breaking even of the lightest boards should only be conducted under the strict supervision of an appropriately qualified person.
