The standing reverse-grip cable curl takes a classic bodybuilding exercise, the reverse barbell curl, and tweaks it by using a handle attached to a cable stack instead. It targets the forearm muscles and brachialis to a greater degree than underhand biceps curl variations. Because grip is a limitation, this move is commonly performed for moderate to high reps, such as 8-12 reps per set or more, as part of an upper-body or arm-focused workout.
