With the black Stamina 3-in-1 Core Training System from RC Willey, you can work your abs in more ways than ever. 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 so many 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.


Available for Online Purchase Only. Assembly required. This product ships direct from the manufacturer, so RC Willey Delivery is not available.
