HOW: Grab a kettlebell in each hand. Press each one up overhead with your elbows locked out. From here, step forward with one leg bending that knee as you stay upright performing a lunge. Alternate lunging forwards with each leg for the prescribed amount of reps or distance. FEEL: You should feel your shoulder muscles working stabilizing the kettlebells. You should also feel your thigh and glute muscles working while lunging. COMPENSATION: Keep your upper body upright, don’t lean forwards or backwards while lunging. Don’t let the kettlebells come down as you lunge. Exercise Library
