What is a TRX Duo Trainer?

Taking the best bit of two excellent training products to create a great product. That’s exactly what TRX have achieved with the Duo Trainer. Creating a more demanding dual-anchor-point system through innovating the industry leading suspension training. The focus was to create another simple training tool that challenged athletes. Enabling them to develop greater levels of strength, mobility, endurance and flexibility. TRX is now a company that can partner with the experts to ensure they are focusing on providing the most effective workout. The TRX Duo Trainer’s design is backed by the expertise of Dr. Kelly Starrett. He is the renowned strength coach and MobilityWOD founder and best-selling author.

The TRX Duo Trainer combines the flexibility of suspension trainers with the benefits of gymnastic rings. It actually adds a whole new level to suspension training. So previous experience with them or advice and training from a PT is recommended.

Benefits of the TRX Duo Trainer

Complete solution: A suspension trainer is a great tool to use for a full body workout. They challenge your strength and core in many different ways. They are also portable and easy to setup, so you can use it almost anywhere. Do a wide range of exercises ranging from muscle building to improving flexibility and burning fat.

Versatility: The TRX Duo offers more versatility than other suspension trainers. The functionality of gymnastic rings allows for more moves that can’t be done on a regular TRX strap.

Limitless Progression: There are many advantages of using your body weight and gravity as resistance. Creating instability forces you to focus on balance and core strength throughout all exercises. Re-positioning your feet and hands will increase difficulty, so you can never outwork or outgrow the Duo Trainer.

Features of the TRX Duo Trainer

Innovative Design: The key feature is the dual anchor point. The separate straps that allow for functional hanging movements such as dips and pull ups. The improved ergonomics provide support during dips, pull-ups and muscle-ups. It also reduces the risk of injury, especially wrist pain.

Infinity loops & mobile grips: The TRX Duo makes quick and accurate adjustments. The straps have clear visual guides to help you make macro and micro changes. Mobile grips increase comfort and ambidexterity. Also the triangle design helps prevent the strap from digging into your forearms.

Wooden straight handles & Foot Cradles: The wooden handles feel great in your hands. The straight design takes into account your hand/wrist physiology. They unload your wrist, are easy to grab and easy to adjust. You will be more confident in loading your full body weight when training.

TRX are now established as the market leader for high quality suspension trainers. They launched their first suspension trainer in 2005 and since then have been developing and innovating their product line.

These products are popular and successful sellers, helping thousand of athletes. The design of the Duo Trainer helps to reduce some common injuries users have experienced using suspension trainers. The straight handles feel natural and greatly reduce the threat of wrist pain. There are many awesome exercises you can do with Olympic rings.
