ALL COLORS ARE THE SAME STRENGTH
Choose your favorite color. Every color performs the same; you and your partner create the intensity.
Two people. One powerful workout.
Partner conditioning, no fixed anchor required.
Inertia Wave® DUO is the two-person oscillating-resistance training system. Face your partner, hold the tubes and create waves together. As the waves move between you, both people must adjust their timing, coordination and core control to keep the movement going.
It's a portable way to bring energy, challenge and interaction to partner sessions, athletic training, boot camps and group fitness classes.
Why choose DUO?
- No anchor. No installation: Two partners hold the tubes and train together.
- Core + conditioning: Continuous waves challenge cardiovascular endurance, rhythm and whole-body control.
- Built for groups: Use multiple DUO sets in braided configurations for coach-led HIIT circles of 4–12 people.
- Ready to travel: Includes a travel bag and guided instruction for 15 partner methods.
What's included
- (2) Inertia Wave® DUO tubes
- Built-in wrist safety straps and cord locks
- (1) Inertia Wave® travel bag
- DUO safety instructions, user manual and access to workout videos (check your email from help@inertiawave.com)
Important safety instructions: DUO must never be anchored to a fixed object. Both partners must wear the built-in wrist safety straps and tighten the cord locks before every session. Allow sufficient clear space between partners.

The battle rope alternative
Inertia Wave vs. Battle Ropes
Battle ropes made wave training popular. The Inertia Wave brings it to a kit under 3 lb that you can use almost anywhere.
Feature
Inertia Wave®
Battle ropes
Weight
Inertia Wave®: Under 3 lb
Battle ropes: Usually 20–50 lb
Space
Inertia Wave®: Fits a hotel room, office or small home gym
Battle ropes: Long ropes need a big, open floor
Setup
Inertia Wave®: Anchors to a rail, door or post (DUO just needs a partner)
Battle ropes: Needs a heavy, fixed anchor point
How it works
Inertia Wave®: The tubes send your energy back, so you work both ways (concentric and eccentric)
Battle ropes: Rope slams send your energy into the floor
Paths of motion
Inertia Wave®: 18 paths of motion
Battle ropes: Only 4 paths of motion
Coordination
Inertia Wave®: Builds timing, hand-eye coordination and cognitive function
Battle ropes: Not built to train coordination or cognitive skills
Intensity
Inertia Wave®: You set it, from first-timer to pro athlete
Battle ropes: The rope's weight sets the load
Noise
Inertia Wave®: No floor slams
Battle ropes: Loud slams on the floor
Durability
Inertia Wave®: Rubber tubes don't fray or unravel
Battle ropes: Rope ends fray and unravel over time
Storage & travel
Inertia Wave®: Packs into a small bag
Battle ropes: Bulky to store, hard to travel with
Battle rope weights and sizes vary by brand; common ropes are 30–50 ft long.

What people are saying
Loved by 150,000+ Wavers
-
★★★★★
“I am loving the inertia wave. I got a solo and a duo and have been using the duo with my clients. I have a spot in the park where I can hook up the solo on the fence. I'm also finding I am able to activate more muscles in my back compared to a regular battle rope.”
-
★★★★★
“I just received my wave duo today and my 3 sons and I watched the videos on YouTube on the 15 movements to do and all we can say is WOW!!! We are so pleased after 1 use and are looking forward to tomorrow to get started our routine that will now include the Wave DUO. I highly recommend you give these a try for a home or even a gym workout.”
-
★★★★★
“I started using Inertia Waves at a cross training class and immediately fell in love with them. And ordered my own pair. Perfect way to supplement my weight workouts and portable enough to pack for travel. I took them with me on a trip to a small town in Mexico and was able to get good metabolic conditioning workouts done attached to a tree! Excellent product!”
-
★★★★★
“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!”
-
★★★★★
“Inertia Wave is the most simple yet effective way for me to workout at home. I’ll only do ten minute bouts periodically through my day but every time I sweat like I’ve done cardio for 45 minutes. For those of you worried about keeping your muscle mass relax...you still get a mean arm pump from using these as well!”
-
★★★★★
“I've purchased a lot of home equipment last couple of months, and nothings compares to the assisting workout the Inertia Wave provides. I've used battle ropes in the past and these provide a better workout than battle ropes. The best part they are easy to take on the go.”
-
★★★★★
“I love Inertia Wave! It’s light weight, comes in a lot of colors, and you can travel with it anywhere! You can use it at home or outside! You get a good workout without hurting your shoulders like the battle ropes!”
-
★★★★★
“The inertia wave is an awesome new addition to my studio gym. The clients are loving how effectively it hits not just the core but the entire body. And for the trainer, it’s ease of setting up makes it simple to take with you anywhere if you need to. We haven’t picked up the battle ropes once since getting the inertia wave!”
-
★★★★★
“It's amazing! I love the fact that I can control the resistance by pulling it further out. The cardio is insane. It torches your arms, shoulders, back and core. Making it a full body workout and it's super versatile; more compact which makes it easy to transport when needed. Also they attach to anything.”
-
★★★★★
“I prefer the inertia wave for my clients more than the battle rope, and it is so much easier to take to my mobile personal training sessions. The variety of exercises with an emphasis of stabilization of the back and core activation is perfect for my clients, and it definitely gets the heart rate up. They really enjoy it and hate it all at once, so you know they are doing it right.”
-
★★★★★
“I absolutely love the Inertia Wave Strong. I had purchased a Solo over a year ago and it quickly became a must in my programming for clients. I was already using Solo to perform some strength exercises with clients but limited to what the grip options safely allowed. So, to have an IW designed and accessorized with everything you need to do it safely and efficiently is the best! 10/10 will buy again!”
-
★★★★★
“I absolutely love the Inertia Wave. I got introduced to it at my gym and it's such an intense and quick workout. I ended up buying a set for home and I can get a great workout in a short amount of time. Best of all, since it's compact to store, I don't have to have a dedicated spot for it in my house.”

Frequently Asked Questions
Everything you need to know before you start waving.
