Seated Leg Extension - Obsidian™ Series
Build your legacy
The quadriceps are one of the strongest muscle group in the body, and need a dedicated option to get the most development out of them.
Leg Extension machines are perfect for this - they're one of the few machines that are universally superior to their free weights exercise equivalent. We stock both plate-loaded and pin-loaded versions to suit. Pin-loaded machines tend to be more friendly for beginners.
Our Seated Leg Extension includes a 138.5kg weight stack, and magnetic pin for ease of use. The weight stack includes 2 x 2.5kg micro adjusters, which can be set independent of the weight. Perfect for progressive overload and percentage based programs, lifters can find the exact weight they need, and make small, consistent jumps in weight as they get stronger.
To ensure your best possible fit, our machine is highly adjustable. Featuring 7 x settings for the shin pad, 6 x settings for the thigh pad and 2 settings for the back rest, allowing an incredible 84 unique total positions!
We use dense padding to ensure you keep a direct connection between yourself and the weight, in order to generate a free weights feel as closely as possible.
Featuring our signature industrial black finish and minimalist logos, insist on nothing but the best for your gym.
NOTE - The commercial pieces can be difficult to install, but are well worth it! We strongly recommend hiring a professional to assemble these, which we can provide as an additional service.

- Can I pick this up?
- We can't accommodate pick ups sorry, but we can ship all over Australia!
- How does the weight stack ratio work?
- Our Seated Leg Extension - Obsidian Series has a ratio of 1:1.5
- Every 1.5kg of weight on the stack = 1kg real world resistance
- The full stack of 133.5kg would be 89kg real world resistance
1. Peace of Mind
With over 500,000 satisfied customers, Iron Edge is Australia's No.1 high performance strength training brand. We've been fitting out elite high performance gyms for the likes of Collingwood Football Club and the Australian Defence Forces for years. We know what you need and what you don't. Our products are constantly being tried, tested and improved to be the best they can be. And we stand behind them accordingly.
2. Product Range
Iron Edge has one of the biggest ranges of high performance training equipment available in Australia. From Nike Romaleos weightlifting shoes, through to kettlebells, Power Bands and weightlifting equipment. In all we stock 100’s of different products at our warehouse facility in Melbourne so you'll always be able to get what you want and, most importantly, when you need it. That's why Iron Edge is the choice of Australia's best athletes, coaches and gyms. And why anything else is just compromise.
3. Engineering
At Iron Edge we employ experienced and qualified engineers to design, test and then source the best manufacturers of all our equipment. Up until 2017 we manufactured in-house, but market pressures forced us to move manufacturing overseas. However we weren’t going to compromise on the quality and structural integrity of our products, so after rigorous research, we’ve been able to partner with some of the industry’s best and most experienced equipment manufacturers. In many ways they are more advanced and sophisticated than our in-house work shop, so you can be assured that the quality of all our products meet the same high standards and are worthy of the Iron Edge brand.
4. Expertise
When you promise 'serious training' you have to back it up. Fortunately we do, drawing on our extensive experience dealing with Australia's best coaches, athletes, sports scientists and exercise physiologists. It's enabled Iron Edge to be one of Australia's leading authorities in high performance strength training- and with an educational arm of the business comprised of over ten certified courses launching soon, we plan on increasing the industry standard across the board.
5. No 'BS' Guarantee
We don't just say our products are the best available. We back it up with an industry leading guarantee. That means if your Iron Edge equipment is faulty or fails to deliver on its promise we will replace it. Conditions do apply.
