Barbell and kettlebell workouts are great for building muscle and strength across skill levels providing good form is followed. With the barbell, you're able to lift more weight and progressively load more effectively to gain strength whereas kettlebells are better for muscle isolation exercises and endurance training. One other factor is the additional equipment often required for the barbell exercises vs kettlebells where little else is needed other than the weight itself. If you're looking for a great barbell and kettlebell workout, then you've come to the right place.
