Frequently asked questions

 Why do I need a bar and platform?

A bar and platform provide a stable base, allowing you to generate more force compared to using bands alone. This setup enables higher resistance levels and full-body engagement, making your workouts more effective for muscle growth. Additionally, it helps distribute force evenly, protecting your hands, wrists, and ankles during exercises.

Can you build muscle with resistance bands?

Yes, resistance bands can effectively build muscle. Studies have shown that training with resistance bands provides similar strength gains to conventional gym equipment.  This is because resistance bands offer continuous tension throughout the movement, leading to significant muscle activation and growth.

What is variable resistance?

Variable resistance refers to the changing resistance levels throughout an exercise’s range of motion. As you move, the resistance increases, aligning with your body’s natural strength curve. This means you’re working against optimal resistance at each point in the movement, leading to improved strength and muscle development.

What makes Heavydutybar different from other band systems?

Unlike traditional band systems, the Heavydutybar features an innovative band-shortening mechanism. This design ensures consistent tension throughout the entire range of motion, addressing the common issue of insufficient tension at the start of movements. This mechanism allows for precise resistance adjustments, facilitating effective progressive overload—a key principle for muscle growth. By providing a stable platform and customizable resistance, the Heavydutybar enhances the effectiveness of resistance band training, making it a superior choice for those seeking efficient and safe muscle development.

Absolutely hooked !!

I genuinely look forward to my workouts with the PO system
The bar has a feel to it that you just don’t want to put down & the hooks are nothing less than sensational - quick & easy to load & once your band or bands are in - its with certainty you can really work with.
Love the tension master ( something I was at first a little unsure I’d get on with ) but changing band length & starting tension to get the absolute most out of each & every band is also quick, easy & assured
The combination of bands that come with it are also top quality, with more than enough resistance options for incredible workouts

Can’t recommend PO system highly enough !

Heavy Duty Bar

The Heavy Duty Bar quality is great. My only criticism and reason for 4 stars instead of 5 is the physical weight of the bar. It was much heavier than one of their competitors bars that holds about the same capacity. Stainless steel versus an Aluminum blend makes a huge difference. I purchased the Bantam bar due to its relative compactness compared to the PO bar. It may be too heavy to travel with on a plane trip. Likely I only know the difference since I have the other product too.

The personnel at Heavy Duty Bar are wonderful and shipping was extremely quick. I highly recommend this company. They do things right without being Cultish like one of their competitors.

Best hooks hands down.

The bar is amazing but as a person that owns every brand of resistance band bars, these hooks change everything. There is no slack regardless of bar or band lengths

I own a couple of the popular resistance band systems on the market and for myself, I find that the HeavyDuty PO Set is the better system all around. Very high quality product along with the ability to shorten the bands to have more resistance from start to finish is what sets them apart. Excellent customer service with fast shipping and very low shipping rates. I will be ordering the shorter Bantam Bar next.

Thank you,
Robert G

I feel strong like Batman in Gotham City holding Bantam Bar

The bar is very well made and it feels very good holding it. The hook design also keeps the bands stable on the hooks unlike the standard metal hooks. I highly recommend this bar.

PO is just as amazing as Bantam Bar!

I have two bars from HeavyDuty Bar and they both are awesome! The quality is there and so is the workmanship and the owners truly poured their hearts into making a stellar fitness product. The Bantam and the PO series are both stellar and if you can only get one, you can’t go wrong with either one of them. I love the fact you can customize the bar before it ships in a thicker grip or bigger hooks. As for the hooks, they spin like butter and the bars feel so solid in the hands. I will for sure be getting more stuff from them and will possibly be looking into a few sets of their resistance bands and their incoming handles and hopefully a curl bar down the road if it’s coming hopefully soon!

Don’t think just buy it!

By far the best band bar on the market hands down! It feels so much better than another company with a gorilla as the company logo. The option to have thicker bars is great and so is the option to have two different hook sizes. I will for sure be getting more products from them in the future!
