    “I have arthritis in my right knee with a fair amount of swelling so it's painful to run. I tolerate the pain because I don't want to give up running. I've used the HeatPulse on it and it takes the edge off of the pain.”

  • David Blough

    NFL Quarteback
    Minnesota Vikings

    “The two things I do to manage stress, is I swim, and I go to the gym. I actually like going to the gym, it's a bit of a happy place. Getting the confidence back to be able to go and do that post-surgery, would be really, really, useful. With the HeatPulse, after the half-hour cycle, I was surprised at how much better my knee felt.”

  • Abby Guistaitis

    Rugby Sevens

    “One day I was fine, and then the next day, I just went to bend my knee, and I started crying. The pain was just terrible. My first try of the HeatPulse, I just finished a long day of ballet, so I put the HeatPulse on, and immediately, I felt relief.”

  • Alli Buchanan

    Relieved of arthritis pain

    “I was crying cause I was in so much pain, I felt like the HeatPulse was something I’ve been missing in my life. The HeatPulse does exactly what my brain wants done to my knee when I’m in pain or when my knee is really swollen.”

  • Robin Arnold

    Relieved of patellofemoral osteoarthritis

    “As I'm 61 years old, I have a focus on fitness and extending my life and my health as long as I can. My whole quality of life was compromised as a result of the pain I was feeling. So my knee, after I take the HeatPulse off, it just feels really comfortable, and really pain-free.”

  • Zoe Barker

    Relieved of arthritis pain

    “Arthritis has affected me quite a lot personally, because I love running. I was absolutely devastated. As soon as I turned this little warming fella on, there was just instant relief. This is taking the pain away, it's soothing it. This is what I thought I had needed for a long time.”

  • Hayley Dixon

    Relieved of rheumatoid pain

    “I thought I was paralyzed. There were weeks that I couldn't actually move. Which meant that I really fell behind on my training. With rheumatoid pain, the best thing that you can do is warm the joints up so they can move more freely. The HeatPulse has definitely made a pretty big impact. Being able to walk around, and cook, and move around the house, as freely as you want. And I wish I had it sooner, after I had my surgery.”

    • Whether you just have a niggle or an ache, or maybe you suffer more chronic pain (this would be brilliant for arthritis sufferers), this tech provides targeted relief.
    • Deeply relaxing. I really enjoyed being able to strap this on wherever, whenever, for a quick on-the-go massage... A one-stop shop for all things dodgy joints.”

    • A premium recovery tool... for all sports lovers. The Atom uses a high-performance BLDC motor that is powerful and quiet, so you can still get a real, deep, and satisfying massage, but with the convenience of being easy to carry.

    Freezing cold and clean water any time of the day


    The Supertub is powered by our energy-efficient Permafrost™ chilling system that keeps your water as low as 37.4°F (3°C) throughout the day.

    It’s engineered to be powerful enough to keep the water ice-cold, while making sure it does not overwork.

    The Supertub comes with a fully-integrated filtration and sanitization system.

    The Supertub is designed to fit homes of all sizes, and is suitable for use indoors or in sheltered outdoor spaces. In addition to its small footprint, it also has a self-contained filtration system so no plumbing is needed.

    With its sturdy but lightweight inflatable design, the Supertub is easy to move around, and can be set up and taken down without professional help.

    It’s also built to last– constructed from double-walled military-grade marine vinyl that we put through rigorous tensile, tearing, and adhesion strength tests, and that is SGS- and ISO-certified for safety and quality.

    What does the Supertub do for your body?

    Boosts physical recovery

    A systematic review of 52 studies showed that cold water immersion is effective in aiding recovery after high-intensity exercise when done 6-8 hours after training or before training.

    Increases energy and focus

    Cold water immersion triggers the release of adrenaline and noradrenaline in the brain and body. These hormones make you feel more alert even for many hours after your cold plunge.

    Builds mental fortitude and grit

    Doing hard things intentionally is hard, but necessary at times. By forcing yourself to face and embrace the stress of cold water immersion, you train and strengthen your prefrontal cortex—the area of your brain that controls impulses and reflexivity.

    Enhances your mood

    Immersing in cold water has been shown to increase the production of beta-endorphins and dopamine—which can give a natural high and improve symptoms of depression.

    Speeds up metabolism

    Going in an ice bath activates the body to burn calories in order to stay warm. The white fat (energy storage) in the body is also converted into brown fat, which the body uses to regulate temperature—which may result in sustained increased metabolism.
