The XPT-900 Sport Self Spotting Power Cage was designed and developed in collaboration by Brady Poppinga (NFL Veteran & 2010 Super Bowl Champion).  With unlimited barbell motion,  the XPT-900 eliminates the need to purchase expensive bumper plates for explosive training.  Safely perform conventional lifts, Olympic lifts, traditional and functional movements, and explosive/competitive movements.

The patented Quad Lock Braking System features four solid-steel locking pins that immediately catch the bar in any position.  The mechanically actuated lever handles (left and right) control the braking system and make racking and un-racking the bar safe and easy. Secondary safety stoppers with quick release levers allow fast and easy adjustments.

The Free-flow, omni-directional guided barbell system allows vertical, horizontal, diagonal, lateral and rotational bar movement to effectively engage all primary muscle groups.  The Olympic barbell is counter-balanced and features a starting weight of 35 lbs.

The XPT-900 Sport incorporates a built-in 1-inch knurled zinc plated pull-up bar, Olympic weight plate storage holders, and 18 bar positions to accommodate any starting height.


What is the difference between a conventional Smith Machine and the XPT-900’s omni-directional guided barbell system?

When it comes to self-spotting free weight machines, everyone is familiar with the tried and true Smith machine.  A Smith machine consists of a barbell that travels on a fixed plane of motion up and down along steel rails, allowing only vertical movement at 90 degrees (or just slightly angled from completely vertical).  The bar on a traditional Smith machine is permanently mounted horizontally so that balance or stabilization of the loaded bar is not factored into the exercise.

The XPT-900 starts with the basic concept of a self-spotting Smith machine, but then explodes past it in all other ways, quite literally.  While a Smith machine is locked into one vertical plane of movement, the XPT-900 is completely free-form, or “3-D” in its movement.  Free-form movement allows the bar to not only move upward and downward, but also forward and backward as well.   Since each side of the bar works independently on its own freely moving carriage, the XPT Training System allows a much more authentic lifting experience.  Both the balance and stability of the bar are factored into the functional movement being performed.


Optional attachment: Dual Adjustable Pulley System (DAP-955) with two 150 lbs. weight stacks (MSRP: $3198.00).
