The PowerLine Smith Machine is a true powerhouse that is often imitated but never duplicated. It's a sophisticated combination of free weight power and resistance coupled with the safety and control of a machine. The Body-Solid Pro-Smith Machine uses four 2" x 2" 12 gauge steel pillars to support and guide the patented Super-Glide carriage during your most vigorous sets. 14 lockout positions and adjustable safeties assure the lifter ultimate safety while striving for greater muscle gains. PowerLine has taken the best equipment out of the health club and engineered it to their own uncompromising standards. Best of all, we made it affordable! Bar is 1" Dia.
