In Stock XG75 & XG90 Compatible 75×75mm Upright Fit Ships Australia-Wide
Leg Extension & Curl Attachment For XG75 & XG90 Functional Trainers, 75×75mm Upright Mount
The Leg Extension & Curl Attachment is a purpose-built add-on for the XG75 and XG90 functional trainers, designed to bring dedicated leg isolation training to your existing setup without purchasing a separate machine. It mounts directly to the 75×75mm uprights on compatible stations, converting your functional trainer into a two-in-one leg training unit in minutes.
If you already own an XG75 or XG90 and want to add leg extensions and leg curls to your programme, this attachment is the most practical and cost-effective way to do it. The seated position, padded shin roller, and adjustable resistance deliver the same isolated quad and hamstring stimulus you would expect from a standalone leg extension machine, but without the footprint or the price tag of a dedicated unit.
Built to the same construction standard as the XG series stations, this attachment is a genuine upgrade to your home gym or PT studio capability, not an afterthought. If you are serious about complete lower body development and already training on an XG75 or XG90, this is a logical and well-engineered addition.

Who Is This For?
-
XG75 or XG90 owners who want to add leg isolation training If you already have an XG series station and want leg extensions and curls without buying a second machine, this is the direct solution.
-
Home gym users who are short on floor space Adding this attachment expands your training options without adding a dedicated unit and the footprint that comes with it.
-
Personal trainers running a PT studio on an XG series station Gives you a complete lower body isolation option for clients within the same training station, without a significant additional investment.
-
Lifters focused on quad and hamstring hypertrophy Leg extensions and curls are the two primary isolation movements for quad and hamstring development, and this attachment delivers both.

Who Should Not Buy This Attachment
This attachment is designed exclusively for XG75 and XG90 stations with 75×75mm uprights. If your functional trainer or power rack uses a different upright dimension, this attachment will not fit and should not be ordered. It is also not suitable as a standalone unit. It requires an XG75 or XG90 base station to function. If you do not currently own one of these stations and are starting from scratch, contact us and we can recommend a complete setup.

Already Training on an XG75 or XG90? Here Is the Gap This Fills.
Most functional trainers cover upper body, core, and cable-based lower body movements very well, but they do not deliver dedicated seated leg isolation. Squats, lunges, and cable pull-throughs are excellent, but they do not replace the direct quad and hamstring stimulus of a leg extension or leg curl. Rather than buying a separate leg machine and using up another metre of floor space, this attachment slots into your existing XG station and closes that training gap directly. It is a practical addition for anyone who is serious about complete lower body development and already training on compatible equipment.

Common Questions
Frequently Asked Questions
Yes. This attachment is specifically designed to fit the 75×75mm uprights used on the XG75 functional trainer. It bolts on directly using the included hardware and requires no modification to the base station.
Yes. The XG90 functional trainer also uses 75×75mm uprights, making it fully compatible with this attachment. The same fitment hardware works across both stations.
This attachment is designed and sized for 75×75mm square uprights as used on the XG75 and XG90 stations. It may fit other equipment using the same upright dimension, but we can only confirm compatibility with the XG series. If you own a different brand of functional trainer or rack, please contact us with your upright dimensions before ordering.
For most home gym and PT studio purposes, yes. This attachment delivers both leg extension (quadriceps) and leg curl (hamstrings) from a seated position, which covers the primary isolation movements you would perform on a dedicated machine. The main practical difference is that a standalone leg extension/curl machine may offer a wider seat adjustment range, but for the majority of users this attachment is a very capable substitute that uses far less space.
Yes. The attachment is designed for both movements from the same seated setup. Leg extensions target the quadriceps, and leg curls target the hamstrings. Both movements are performed in the seated position using the same shin roller pivot arm.
Installation is a straightforward bolt-on process using basic hand tools. The attachment comes with all required mounting hardware and assembly instructions. Most users are able to complete the fitment without specialist assistance. If you are in the Sydney metro area and would prefer professional fitment, our installation team can assist.
No. The attachment bolts on to the upright using the included hardware and can be removed without any permanent changes to the base station. This makes it practical for users who want to switch between attachment configurations.
The weight capacity for this attachment is currently being confirmed with our supplier. Please contact us directly at 1300 247 888 or [email protected] and we will provide the confirmed figure before your order is placed.
This attachment is suitable for home gym, garage gym, and light commercial use such as PT studios. It is designed to match the construction standard of the XG series stations it attaches to. For heavy-duty commercial environments with high daily usage, please contact us and we can advise whether this or a dedicated commercial leg machine would be the better fit.
Our showroom is located at 10/202 Milperra Road, Milperra NSW 2214, open Monday to Friday 9am–5pm and Saturday by appointment. Contact us before visiting to confirm the attachment is currently on display, as showroom stock changes. Call 1300 247 888 or email [email protected].
Yes. This attachment ships Australia-wide via freight carrier to metro and regional addresses. Contact us for a freight quote to your location. Sydney metro customers may also be eligible for direct delivery with installation.
Warranty details for this attachment are currently being confirmed. Please contact our team at 1300 247 888 for current warranty information before purchase.
For most XG series owners, yes. A dedicated leg extension and curl machine represents a significant additional cost and a considerable footprint. This attachment adds both movements to your existing station for a fraction of that investment and without occupying additional floor space. If leg isolation is part of your training programme and you already own an XG75 or XG90, it is a practical and cost-effective upgrade.
No additional equipment is required beyond the base XG75 or XG90 station and this attachment. The attachment uses the station's weight stack for resistance. No separate weight plates or cables are needed. Everything required for installation is included in the box.
The simplest way is to contact us directly. Call 1300 247 888, message us on WhatsApp at +61 412 029 000, or email [email protected]. Provide your station model and upright dimensions (if known) and we will confirm compatibility before you place your order.

Most functional trainers cover upper body, core, and cable-based lower body movements very well, but they do not deliver dedicated seated leg isolation. Squats, lunges, and cable pull-throughs are excellent, but they do not replace the direct quad and hamstring stimulus of a leg extension or leg curl. Rather than buying a separate leg machine and using up another metre of floor space, this attachment slots into your existing XG station and closes that training gap directly. It is a practical addition for anyone who is serious about complete lower body development and already training on compatible equipment.

Common Questions
Frequently Asked Questions
Yes. This attachment is specifically designed to fit the 75×75mm uprights used on the XG75 functional trainer. It bolts on directly using the included hardware and requires no modification to the base station.
Yes. The XG90 functional trainer also uses 75×75mm uprights, making it fully compatible with this attachment. The same fitment hardware works across both stations.
This attachment is designed and sized for 75×75mm square uprights as used on the XG75 and XG90 stations. It may fit other equipment using the same upright dimension, but we can only confirm compatibility with the XG series. If you own a different brand of functional trainer or rack, please contact us with your upright dimensions before ordering.
For most home gym and PT studio purposes, yes. This attachment delivers both leg extension (quadriceps) and leg curl (hamstrings) from a seated position, which covers the primary isolation movements you would perform on a dedicated machine. The main practical difference is that a standalone leg extension/curl machine may offer a wider seat adjustment range, but for the majority of users this attachment is a very capable substitute that uses far less space.
Yes. The attachment is designed for both movements from the same seated setup. Leg extensions target the quadriceps, and leg curls target the hamstrings. Both movements are performed in the seated position using the same shin roller pivot arm.
Installation is a straightforward bolt-on process using basic hand tools. The attachment comes with all required mounting hardware and assembly instructions. Most users are able to complete the fitment without specialist assistance. If you are in the Sydney metro area and would prefer professional fitment, our installation team can assist.
No. The attachment bolts on to the upright using the included hardware and can be removed without any permanent changes to the base station. This makes it practical for users who want to switch between attachment configurations.
The weight capacity for this attachment is currently being confirmed with our supplier. Please contact us directly at 1300 247 888 or [email protected] and we will provide the confirmed figure before your order is placed.
This attachment is suitable for home gym, garage gym, and light commercial use such as PT studios. It is designed to match the construction standard of the XG series stations it attaches to. For heavy-duty commercial environments with high daily usage, please contact us and we can advise whether this or a dedicated commercial leg machine would be the better fit.
Our showroom is located at 10/202 Milperra Road, Milperra NSW 2214, open Monday to Friday 9am–5pm and Saturday by appointment. Contact us before visiting to confirm the attachment is currently on display, as showroom stock changes. Call 1300 247 888 or email [email protected].

Warranty details for this attachment are currently being confirmed. Please contact our team at 1300 247 888 for current warranty information before purchase.
For most XG series owners, yes. A dedicated leg extension and curl machine represents a significant additional cost and a considerable footprint. This attachment adds both movements to your existing station for a fraction of that investment and without occupying additional floor space. If leg isolation is part of your training programme and you already own an XG75 or XG90, it is a practical and cost-effective upgrade.
No additional equipment is required beyond the base XG75 or XG90 station and this attachment. The attachment uses the station's weight stack for resistance. No separate weight plates or cables are needed. Everything required for installation is included in the box.
The simplest way is to contact us directly. Call 1300 247 888, message us on WhatsApp at +61 412 029 000, or email [email protected]. Provide your station model and upright dimensions (if known) and we will confirm compatibility before you place your order.
