The New Shape of Core Fitness

I created the AbStar Core Trainer to help me and others safely and efficiently improve core fitness and achieve fantastic total body workouts.

Most people want to look better and feel better. Using the AbStar Core Trainer can help you start and maintain a safe, effective core fitness routine. Additionally, you can improve your total body fitness at home or in the gym through versatile and effective seated, standing or reclining exercises.

The AbStar Core Trainer has no moving parts, nothing to put together, and no hinges or metal parts that could potentially hurt you. Simply pump it up and it’s ready to use.

With its unique patented design, low-height, anti-slip base, and sturdy construction,  you can perform scores of core and total body exercises which makes the AbStar Core Trainer safer, more versatile AND more effective than other core trainers.

Pump up the AbStar Core Trainer with the easy instructions below.

Because of the unique patented design and resilient, durable material that compose the AbStar Core Trainer, our engineers recommended we employ an industrial-strength inflation valve, rather than a simple air hole and plug that exercise balls can use. Our high-quality design and materials increase the longevity, strength, and safety of the AbStarCore Trainer. It's so strong, you can pump it up once and use it forever.


  1. Hold the screw end of the steel inflation needle between thumb and index finger.
  2. Pinch insertion point on the bottom of the AbStar Core Trainer with opposite hand, then push the point of the needle into air bladder, twisting gently. Continue until the needle is fully inserted.
  3. Screw pump onto the inserted needle and begin pumping.
  4. Pump until the device is approximately ten inches high, or to preference, then gently remove the needle.
  5. If you ever need to partially or fully deflate your AbStar Core Trainer, insert needle without pump attached and allow air to escape.
  6. Store pump and needle in safe place.
  7. Wash your AbStar Core Trainer with soap and water, and then dry thoroughly. It is now ready for use.
