The reverse curl. When performing a reverse curl you can either use an EZ curl bar or a straight barbell. Don’t go in thinking that you can lift a similar weight to what you can with an underhand grip because you won’t. Start with around half of the weight that you’d usually use for a regular barbell. The isotonic motion is the same but your palms are facing downward. Unlike, bicep curls where you hold the barbell or dumbbell with your palms facing towards you. Rarely seen to be used in the gym
