Why Sumo Strength
Australian Owned & Operated
Sumo Strength is proudly 100% Australian owned and operated. Our headquarters in Cranbourne West, Victoria is home to a team deeply experienced in product design, engineering, and strength training. We design equipment built for Australian conditions and real-world performance, with an additional warehouse facility in Brisbane to ensure fast fulfilment nationwide.
Our belief is simple: strength and fitness should be accessible to everyone. Whether you're building a home gym, upgrading a commercial facility, or taking your first step into resistance training, our mission is to deliver equipment that helps you train with confidence.
Price Match Guarantee
We’re committed to offering exceptional value — and we back it with our Price Match Guarantee.
If you find a lower price on an identical, in-stock item offered by an Australian competitor, we’ll match it.
To qualify, the item must:
-
Be the same product, brand, specification, and quality
-
Be in stock and available for immediate purchase
-
Not be part of commercial quantities, liquidation sales, clearances, or bulk-order quotes
Shipping charges can vary significantly by carrier and location, so these are not included in price matching.
To request a price match, simply reach out via our contact form or live chat with screenshots or links. If approved, we’ll provide a seamless checkout process at the matched price.
100-Day Home Trial
We’re confident you’ll love training with Sumo Strength — so we give you 100 days to try our equipment at home or in your commercial gym.
If you’re not satisfied with any item within the trial period, we’ll provide a no-fuss refund of the product value once it’s returned.

FAQ
Who pays for shipping on returns?
We fully refund the item value if it doesn’t meet your expectations — but shipping costs, both original and return, remain the customer’s responsibility.
Do I need to keep the packaging?
Yes. All original packaging (including internal supports and foam) must be retained. Returns cannot be accepted without it.

A full breakdown of warranty periods is available in our Warranty Policy.
Warranty coverage excludes:
-
Cosmetic wear
