Pedals and bottom bracket (BB) cups aren’t all threaded normally. For most American and British bikes (Italian and French bikes are different (of course)), the pedals can be loosened by turning the wrench toward the BACK of the bike. Bottom bracket cups can be loosened by turning the wrench to the FRONT of the bike.
Print this out on acetate, so you can look through it from the back when you go around to the other side of the bike.
