Lock 'n' Load for the Gun Show I remember as a kid enjoying the pleasure of standing behind the sideline of an NFL game. The players were massive. TV does them no justice.Monsters masquerading as men. The only visible parts of their bodies not hidden under layers of pads, braces and wraps, were their arms.Hearing the tackling astonished me. The crunching and cracking resembled car crashes, train wrecks and building collapses. The defensive linemen and linebackers stalked back to the bench, their arms sweaty, bulging and bloodied. Mistaking their arms for Medieval battering rams smashing castle gates didn't stretch the imagination.Then I saw Arnold in The Predator. His arms were HUGE and made his AR-15 slab-side M16 rifle look even deadlier. Biceps changed forever.Do you want yours to change? Fear Factor Arguably, big biceps may not serve much of a functional purpose, although it's difficult to deny the intimidating appearance of large, defined arms. Read on if you agree. Animal intimidation techniques have existed for millennia and humans are no different. Whether a puffed up puffer fish or a chest-beating silverback gorilla, physical displays of status on the dominance hierarchy aren't novel or new.Don't let evolution pass you by. Define your arms and bulk them up with our loadable dumbbell. Why a loadable dumbbell you ask? Do you lack the space for a whole array of traditional dumbbells? Do you want to lift the precise amount of weight that you want? Do you want complete control over your training? Armed and Dangerous Our loadable dumbbell boasts the same rugged design and durability we're known for. Using high tensile strength steel, we've produced a fine specimen that looks like the offspring of our barbells. The loadable dumbbell also features a spinning sleeve for smoother lifts. It would be dangerous not to add this loadable dumbbell to your arsenal, as you'll be falling behind in the arms race. As Ed Coan said, "Biceps are like ornaments on a Christmas tree."Do you want to have a Charlie Brown Christmas tree? Load up to 220lbs on each dumbbell handle. Can fit regular barbell collars with 2 inch diameter. Each handle will need a pair of collars, 2 pairs for a pair of handles.
