Free weight workouts have a lot of benefit over gym machine based ones, in that they often work more muscles since you also have to focus on stabilization when lifting which recruits more muscles than if using a gym machine. Free weights include barbells, dumbbells and kettlebells - basically anything that you have to support yourself and aren't attached to anything. Free weight exercises tend to be better for intermediate and above skill levels since form is a critical factor and each has an inherent risk of injury if performed incorrectly. If you're looking for great free weight workouts, you've come to the right place.
