10 minutes to remove stuck bicycle pedal seized from crank arm without breaking wrench. After breaking the wrench with cheater bar/extension, WD40 didn't help, I do more reading. People suggest to either heat or freeze the pedals since aluminum crank arm expands/contracts 5 times more than steel pedal axle.
I decide to just freeze it with cup of snow and wait 5 minutes before hitting it wrench and hammer.
As quoted from Sheldon Brown website:
To remove "frozen" pedals from an aluminum crank, remove the crank and pedal from the BB spindle, heat the pedal end of the crank over gas flame cooking stove until it sizzles to the wet touch. Using a pedal wrench, the pedal usually unscrews relatively easily without damage.
