It's all about the wave

How Does Inertia Wave Work?

It's all about the wave. Create rhythmic movements through our patented resistance system and experience a unique combination of cardiovascular conditioning, core engagement, and muscular endurance.

  1. Set It Up

    Secure the SOLO or STRONG models to a suitable anchor, or team up with a partner using the DUO model.

  2. Create The Wave

    Use controlled, rhythmic movements to generate continuous oscillating waves through the elastic tubes.

  3. Feel The Resistance

    The waves create dynamic resistance that challenges your muscles, core stability, and coordination.

  4. Control The Intensity

    Build momentum and adjust your pace to create a workout that matches your fitness level.

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.

    “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.”

    Kalman L. SOLO & DUO · Personal trainerGoogle review

    “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.”

    David A. DUO · Family workoutsGoogle review

    “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!”

    Debra B. Travel & classesGoogle review
  • ★★★★★

    “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!”

    John K. Home workoutsGoogle review
  • ★★★★★

    “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!”

    Michael U. Studio gym ownerGoogle review
  • ★★★★★

    “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.”

    Elisa H. Full-body conditioningGoogle review
  • ★★★★★

    “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.”

    TJ G. Mobile personal trainerGoogle review
  • ★★★★★

    “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!”

    Emmanuel M. STRONG · TrainerGoogle review
  • ★★★★★

    “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.

What is the Inertia Wave?

A patented, portable oscillating-resistance trainer. You pulse the tubes and they pulse back, so every wave works your core, arms, shoulders and legs together. It weighs under 3 lbs and packs into a travel bag.

Which model should I choose?

STRONG is our best seller: wave training plus clip-on hand grips and belts for strength exercises. SOLO is the original anchored trainer for core and conditioning. DUO is the two-person model for partner and group training and never needs an anchor.

Do different colors have different resistance?

No. All models are equal in strength, and color is only a preference. You control the intensity with how hard and fast you create the wave.

How do I anchor SOLO or STRONG?

Anchor straps are included. Secure them to a sturdy rail, post or pole, or use our Door Anchors (sold separately). See Creative Ways to Anchor for step-by-step videos.

Does the DUO need an anchor?

No. The DUO is held by two people facing each other and should never be anchored to a fixed point. Braid several DUOs together to train groups of 4 to 12.

What's included with each model?

STRONG: Inertia Wave tubes, anchor straps, two clip-on hand grips, two long belt attachments and a travel bag. SOLO: Inertia Wave tubes and anchor straps. DUO: two-person tubes with safety straps and cord locks, plus a travel bag.
