Now you can lock your feet in place with the Sunny Health & Fitness sit-bar to help you perform the proper sit up.

The metal tends to give more than the prior two models, which for some users appears to be more of a benefit than a deal-breaker.

  • 3 height levels adjustable bar
  • comfortable foam padding
  • steel structure – slight give
  • 1 screw knob & 1 wing nut
  • inexpensive

The Ader Doorway sit up bar is strikingly similar to the previous model, however slightly more expensive.

Basically, you are getting all the same features as the Sunny Health & Fitness but at a higher price tag. Do feel free to compare the two, however, I would suggest going with the cheaper option.

  • lightweight compact design
  • 3 height levels adjustable bar
  • comfortable foam padding
  • steel structure
  • 1 screw knob & 1 wing nut
  • slightly more expensive

#5 YNXing Self-Suction Sit Up Foot Anchor

YNXing self-suction ab workout bar

The YNXing is not a doorway sit up bar but rather a self-suction sit up bar that can be attached to the floor with the built-in suction mechanism.

The concept behind this device is good but I’m not convinced that it is reliable for assisting with situps. Most users complain about it not sticking to the floor properly or coming lose while performing sit ups.

If you have a marble floor or very smooth tile, you could possibly give this a try. Personally, I would not recommend this product.

  • lightweight compact design
  • adjustable gears for height
  • comfortable foam padding
  • suction mechanism
  • only use on a smooth surface
  • not reliable

How To Install Your Sit Up Foot Anchor

Installing a doorway sit up bar is very quick and easy. With the door open, simply slide the bar onto and down the bottom side of your door. While holding the device up against the door simply tighten it in place by turning the adjustment screw to the right.

Most bars provide foam pads that are located on either side of the device to prevent damaging the door.

I find positioning the sit-up bar in the middle of the door provides better weight distribution and even pressure on the door for more stability.

Must have accessory: Whether you invest in a doorway situp bar or not, I would highly suggest looking into buying an abdominal situp pad, also known as a core mat. These small mats not only extends the range of motion and thus engaging more core muscles, but also aids by takes the jerking motion out of the situp.

How To Use a Doorway Sit Up Bar

After you have installed your door sit up bar properly, it is time to get busy working on those abs.

Firstly, I would advise everyone to wear workout shoes. This will give you better leverage and support, is easier on your feet, and if you have very small feet can provide you with a better fit.

How you position your feet under the bar is up to you, and will determine what height you want to set for your ab workout. Some prefer higher to use the top part of your feet towards the toes, and other lower for more ankle support.

Making these adjustments is fairly simple. Most doorway sit up bars have 3 to 4 height levels which can be easily adjusted by re-positioning the footpad and then locking it in place with a simple twist of a knob.

Final Thoughts and Recommendations

The doorway sit up bar is one of the most inexpensive yet functional and effective devices I have come across for exercising your abs. These bars are very effective at helping you keep your body in a stable position to accurately perform sit-ups.

I chose the TKO sit-up bar as my #1 pick for two reasons. The first being the added width of the base clamp that attaches to the door. This design creates a stronger hold and also less pressure per square inch on the door itself, and therefore less likely to damage the door.

Secondly, besides having a total of 4 adjustable heights (more than any of the other models) and 2 easy to adjust knobs for both the clamp and the height adjustment, it is also the second most affordable after the CAP Barbell doorway sit up bar.
