The kettlebell front rack lunge is a dynamic leg and core exercise in which a lifter performs lunges while holding a single kettlebell in the front-racked position. It is a unique coordination challenge, but also challenging to the musculature of the abdomen, lower body, shoulders, and upper back. It is most commonly performed for higher reps, such as 10-15 reps per side, or for time. It can work in circuit-style workouts, as well as in muscle or strength-focused workouts.
