THE KOLOSSOS - Smith Functional Trainer

The Hydra series uses 2x3 inch uprights with 5/8 inch holes, making it compatible with a wide range of standard accessories. The Manticore series is built with 3x3 inch uprights and 1 inch holes, offering a heavier-duty feel and compatibility with larger, competition-style attachments.

No, the Smith machine is designed for solo training. It features built-in safety catches and smooth linear bearings that allow you to safely rack the bar at any point in the movement, even if you fail a rep.

The 2:1 ratio means that for every 20lbs selected on the weight stack, you are lifting 10lbs of actual resistance. This setup provides a smoother, more controlled feel during movements and allows for finer weight increments, which is ideal for isolation exercises.

Compatibility depends on which ecosystem you choose. If you select the Hydra rack, it works with most 2x3 inch attachments with 5/8 inch hardware; the Manticore rack works with 3x3 inch attachments with 1 inch hardware. Always verify your existing attachment's hole size and upright dimensions before purchasing.

While the rack itself is 90 inches tall, you should account for at least an additional 6 to 12 inches of clearance above the unit. This extra space ensures you have enough room to perform pull-ups or overhead movements comfortably without hitting the ceiling.

The Kolossos comes with dual 210lb weight stacks integrated into the functional trainer. You do not need to purchase additional weight plates to use the cable system.
