Chin up, pull up bar, push up bar and sit up bar it's all the same, it's one product. This is a great home fitness product for all the exercises you can do with it. Being able to adjust the bar either at the top or bottom of the doorway gives you an assortment of exercises. The bar has an adjustable width that fits different sized doorways, along with a solid build makes this a great candidate for anyone looking for a quality, versatile home fitness equipment. I can do a variety of exercises like dips, pull ups, push ups, sit ups and more, hitting the upper body and abdominal muscle groups. This pull up bar is sturdy and removable which is the most important to me. Now it's not screwed in for good and always in the doorway. Lastly I trust the stability of it as long as I trust the doorway I've installed it in.

I'll have to admit, once this thing is installed (make sure you have a power screw driver) it is awesome. We set it up in our warehouse to film the video. It's extremely sturdy and could easily hold 200 lbs + in our not-so-strong doorway.

I have a different pullup bar that I purchased years ago by another brand. This one is similar, except for two things: the grips and the second set of clips to put the bar in. The grips are non-slip no matter how hard you twist, which is huge to me because I hate that slippery-metal feel. The second set of clips is seemingly minor, but enables you to have the chinup bar at two levels so you can also put it down by the floor for pushups & situps.

A+ product for the price in my opinion.
