Strength is the foundation of health. Strong people have denser bones, regulate blood sugar more efficiently, burn more calories at rest, are harder to injure, and enjoy a higher overall work capacity. 

Barbells are the best way to get strong because they allow the trainee to use the most muscle mass to move the most weight over the longest range of motion. Bars as light as 5.5 pounds mean that there is no barrier to entry. Plates as small as 1/4 of a pound ensure that everyone can progress at the rate that is appropriate for them. Barbells are for everyone.
