Walk through any hardcore gym or athletic strength and conditioning facility and you’ll see chains and bands lying all over the place. Start using these by putting them on the ends of barbells and dumbbells. This is known as accommodating resistance. As you lift, the weight gets heavier; for example, at the bottom of a bench press the bar plus weight and chains will amount to 100 pounds (because some of the chain links are on the ground), but at the top it will weigh 150. This is all too often overlooked as a way to increase strength and size quickly. Start using chains and watch your progress go through the roof.
