I stumbled upon this cap barbell weighted workout bar the other day while browsing on Amazon, and was pretty happy that these things existed! What a great idea for home workouts and a great addition to a home exercise equipment collection.

Personally, I love barbell work but always thought I’d be limited to having to find a gym in order to be able to use this kind of equipment. Now that I’ve discovered that these weighted workout bars exist, I’m thrilled that something like this can be easily used for home barbell workouts!

What is a Cap Barbell?

I did a bit of digging because I wasn’t sure about the exact name for these bars.

I thought they may have been called “cap barbells” since they have look like they have two caps on each end.

So what is a cap barbell? Apparently (after much confusion on my end) the phrase “cap barbell” does not refer to a type of barbell, but it is actually a popular U.S. brand that manufactures all kinds of weights (including dumbells, barbells, kettlebells, you name it).

Weighted Workout Bar

After I finished figuring out the name for the piece of equipment I was actually looking for (“Weighted workout bar” or “Padded weighted workout bar“),  I jumped on to Amazon to do a bit more research.

There are a few companies that make weighted workout bars, which are often covered in a soft foam or padding to allow for a more comfortable grip.

This also helps it sit easier on shoulders if you’re holding the bar in this position when doing exercises like weighted lunges or squats.

These workout bars resemble a barbell and are designed to be used at home or independently without the use of weight plates.

The weighted bars are great for home barbell workouts, and I actually came across them when looking for something to use for the home workouts in The Butt Bible (one of my favorite workout programs).

Who Will Enjoy the Weighted Workout Bar

I think that anyone who likes to do barbell style workouts at home, but doesn’t have room for a traditional barbell and plate set will really enjoy and benefit from a weighted workout bar.

Sure, they are nowhere near as heavy as a regular barbell, but they are a good substitute if you just want to add a little bit of extra resistance to your usual workout.

Pros of Weighted Workout Bars
  • Compact & easy to store
  • Fixed weight sizes – no fiddling around with adjustable weight plates

How To Choose a Weighted Bar

There are many different brands of weighted bar out there, so how do you know which ones are good and which one you should purchase?

I suggest first picking a weight that you’d like to start with, and then investigating different products from there.

What Weight Should I Start With?

This depends on the particular exercise you are doing as well as your personal fitness level.

If you have access to dumbbells or a gym, it could be worth testing your strength with any available weights to get a feel for how much weight you find challenging for different exercises.

You can then make your bar selection based on this.

My Recommendation

Weighted bars are an excellent addition to any home exercise equipment, and can make for a good barbell substitute if you just want a little bit of extra resistance.

Of course, if you’re really wanting a challenge then there’s no substitute for the real thing – you may want to get yourself to a gym if you are wanting access to barbell weights that are more than 36 lb.

My picks after reviewing all these products are:

Amazon’s pricing tends to change so it is worth checking a few different manufacturer’s prices to get the best deal. Another key feature to look for is other user’s reviews, as each product generally differs slightly in its features and quality.

All I know is, I’m very happy because this means I can stop using the old broomstick in place of a barbell, and actually something more suited for working out!

Have you heard of, or tried these kind of weighted workout bars before? What did you think?

    Hi Jolie
    Very nice review and informative. Is the bars available in kilograms as well?

    • May 18, 2015 at 4:42 am

      Hi CT, thanks for your comment.
      As far as I can tell, these may be quoted in kilograms depending on the country they are made in (or marketed for). However, it’s easy to do the conversion: just divide pounds by 2.2 to give the equivalent weight in kilograms! E.g. 20 pounds = 20 / 2.2 = 9 kilograms.

      Hope this helps!

    hi Jolie
    I use weighted bars at the gym all the time. Not necessarily for my butt but rather for my abs. I think they work quite well and I like the variety in weight they offer. However, if I were to use them to work on my butt I am thinking that I would need a heavier one for squats or lunges. More like 30-40 pounds. I find most of them comfortable to put on your shoulders but the quality does vary as you point out

    • May 18, 2015 at 4:38 am

      They are great because they are so versatile – there are so many exercises that can benefit from the addition of a weighted bar.

      I know what you mean in terms of squats and lunges – most people can usually handle more than 30+ pounds. However, I do think these weighted bars are a great ‘gateway’ to those heavier weights.

      You can also get some serious butt burn from using these bars with exercises like one legged glute bridges and hip thrusts – and these are some of the best exercises for glutes that you can get.

    Very well thought out site. You’ve obviously done your research on cap barbells. I think they’re a great idea and would make a good gift.

      Hi K, thanks for your comment – I do hope this helps anyone who is looking to buy a padded weighted bar and isn’t sure which product to go for. Cheers!

    I use one of these bars at the gym, absolutely love it. We use it for one of the “bootcamp” classes and it`s easier than a regular bar to use, I think.
    Thinking of getting one at home as well,

    Great article thanks!

      Thanks Vicky, yes the padding on them does make them a lot more comfortable and easier than a regular bar!
