Features of the Inertia Wave DUO

Body building meets team building.

Built specifically for team or group-based workouts, the Inertia Wave DUO is a two-person tool with a resistance profile like no other device on the market today increasing movement, speed, strength and hand-eye coordination, teamwork, and communication.

No anchoring systems required.

With the Inertia Wave DUO, no anchors or attachments are needed to start training. You and a partner hold the opposite ends of the tubes and work together to perform the various methods of use together.

Safety first!

Safety is of the utmost importance! The Inertia Wave DUO comes with durable safety straps built into the tubes that attach securely to your wrists. This prevents the tubes from lashing back at the opposite user in the event that you lose your grip. Always wear your safety straps.

We recommend, for your safety, never pulling or stretching the Inertia Wave® DUO longer than 26 inches. It’s not a bungee and it may lose its integrity if you use it like a resistance tube.

You will void all terms, and be held accountable for any injuries.

It is the user's responsibility and the user's negligence for the causation of any injury. User must be aware of sweaty hands, surroundings, and anything that may harm spectators or yourself. It is mandatory that you wear safety straps at all times.

The original Inertia Wave has a solid steel O-Ring built into it. If a user were to let go, it can become very dangerous. The Inertia Wave Duo has safety straps instead. The Inertia Wave Duo has been tested and quality controlled and approved safety straps.

Although we urge you to get creative with your Inertia Wave products by coming up with unique custom methods, you should never use them as a resistance tube or bungee. It will loose its integrity and can possibly cause you harm.

From your partner's hands to your own, you will need at least 11.5 feet in length. To perform the Hurrican Walk method, you will need more space to walk forward and back.

For some of the methods of use, you will need at least 4 feet in width to your left, and 4 feet in width to your right.

For some of the methods of use, you will need at least 7 feet in height from the ground.

No. The Inertia Wave Duo was designed with a built-in "wrist safety strap" at each end of the tubes. If you try to tie the safety strap and use it as an anchor, the safety straps may rip out. The safety straps are strong enough to stop the end cap from flying towards your partner, however, cannot withstand 300-600 lbs. of oscillating torque which it produces as its anchored. PLEASE do NOT attempt to anchor your Inertia Wave Duo.

I just have one word to describe IW OMG!!! So in Love with it, easy to anchor and the Best to make your CORE stronger, and I just started using it❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️

Overall good idea. This is great for beginners but not effective for those that already have a moderate cardio and muscular endurance base. Also, note that you need multiple anchor points vs. a battle rope, that may make a big difference in your decision process.

Absolutely love the Inertia Wave. I was looking for another way to do HIIT since I primarily use a spinner and my legs got tired. This is a great alternative to still get the heart rate going without using up my legs. Prefer it over battleropes since it has a lot more core activation/stability

I love the interia wave. They’re easier on your joints and are more compact than battle ropes. They’re also really easy to anchor. I would definitely recommend this product to anyone else. 5 stars.

Great piece of equipment and clients are loving it as a nice little finisher for their session, without their joints aching from the old cumbersome battle ropes.

The Inertia Wave is everything it claims to be. I am so pleased to add it to my routine. The Fabulous 3! TRX, CFX & Inertia Wave!

I have the anchored and duo I love them both ❤. Very easy to transport and hook up almost anywhere to get an extreme burn and conditioning. I couldn't believe how just 30 seconds of work had me sweating. The lightweight gives me the ability to create so many different movements. I incorporate the IW into all my sessions now!

I've done heavy battle ropes before, but these are so much better... really easy to store, easy to clean (shouldn't get musty or moldy like the ropes). As for the workout - it was really, really good. I did three of the simple workouts and it did a great job working my arms and shoulders. Also, because I signer have to worry so much about the weight of the cords, I was better able to focus on form. A really perfect HIIT, and unlike the regular ropes, I have these stored very easily and in a small space.

Customer Service was amazing and I got my items on time. Thank You. You guys are awesome. I wrote the wrong address and you guys called FedEx and sorted it out. I bought the Duo in the past for a Bootcamp now that gyms are closed I decided to get the original so I can workout in the park by myself. Great Product

Needed to replace my battle ropes and I saw an ad for Inertia Wave, so said why not give it a try. Well I tell you they are awesome. I train clients in a near by park, and the Inertia Wave is light and easy to set up. I’m still learning everyday how versatile they really are!

Best product out for strength and stability. The Inertia Wave is a full body workout for any age individual. Great for gym use or with any athlete training for a sport. Every athlete who comes to my facility has to use it before they leave! Chris Marlo Light Tower Baseball Training

Inertia Wave had amazing customer service. I reached because of the student/Healthcare professional tab and got a personalized message back from the owner of Inertia Wave. It's really a unique piece that can get you a solid pump and HIIT workout at the same time. So happy I found them. Can't wait to use them in my future clinic.
