Stamina 3-in-1 Core Training System



Our Most Comprehensive Core Equipment Yet
With the 3-in-1 Core Training System, you can work your abs in more ways than ever. You can perform decline or flat sit-ups, crunches and now, even knee raises with our Ab Arc. Plus, the Ab Arc features an electronic monitor so you can track your progress based on the number of reps.

Don’t Neglect Your Legs and Arms
The adjustable-angle, padded bench allows you to perform many other exercises, including bicep curls, bent-over rows, split squats and more. All you have to do is adjust the bench to the flat position. Plus, the Ab Arc also incorporates your upper body, so you’ll definitely feel the burn in your arms and core before your workout is finished.

Utilizing the Adjustable-Angle Bench
Not only does the 3-in-1 Core Trainer save you space, it saves you time. You no longer have to drive to the gym. Even more, it doesn’t take long to adjust the trainer between exercises. The bench adjusts between the flat and decline position easily. Just pull the pin, slide the bench into the desired position, then replace the pin.

Switching Between Knee Raises and Sit-ups/Crunches
When it comes to locking in the Ab Arc’s foam rollers for sit-ups and crunches, simply adjust the rollers to the desired height and replace the pin (the pin should not be in the arc when performing knee raises). You can also choose whether you remove the Ab Arc’s handles or leave them on, which can assist you during sit-ups and crunches.


  • Three ways to use the Core Training System: crunches/sit-ups, a weight bench and our Ab Arc for knee raises
  • Multi-function monitor to track your progress on the Ab Arc
  • Padded, upholstered, adjustable-angle bench for decline or flat sit-ups, crunches and weight lifting
  • High-density foam rollers cushion the ankles and knees
  • Padded handles for Ab Arc detach easily for other exercises
  • Leveling endcaps to stabilize
