There can be many reasons why people don’t want to use a barbell. It could be because of a back pain or your general dislike for the barbell that you want to stay away from it. It is said compound movements with a barbell are the best way to build big legs. Your muscles have no idea if you’re using a barbell or dumbbells. All they know is if you have trained them to failure. You can completely eliminate barbells and other machines from your leg workouts and still build monster wheels. ~ Berceste
