Lunges are one of the most basic and effective exercises you can do to target your booty and legs. Adding weights to the move makes it way more intense. Try this variation that will not only challenge your sense of balance but will also definitely leave you sore tomorrow.
You can do this exercise holding dumbbells or kettlebells, or place a barbell in the front or back rack position for more of a challenge. Be sure to do the same number of reps on each side.
