As we exercise our body and muscle temperature increases. This increased temperature leads to a decrease in our ability to perform and also decreases our motivation to continue working.
Our devices use materials that specifically optimizes the glabrous skin found on the palms of your hands. This type of skin contains specialized blood vessels that rapidly exchange heat with the environment, making it ideal for efficient cooling. By targeting glabrous skin, palm cooling quickly reduces core body temperature, enhancing recovery and improving performance during intense activity.
The palms are covered by glabrous skin. Glabrous skin is hairless and has an amazing network of veins and arteries underneath called arteriovenous anastomosis (AVAs). This special network is incredible at helping regulate temperature.
It is incredibly simple to use the AF Charge Bar. Prior to your workout, practice or competition be sure to cool your charge bar by sticking it in a refrigerator or refill it with cold water. The tool is designed with a certain type of metal and density that allows it to keep its temperature for up to an hour when filled with cool water. Ideally, the temperature of the AF Charge Bar is between 45-60 degrees Fahrenheit when being used.
To use the tool after it is cooled, simply hold the bar during rest periods. Rest periods could be between sets of strength training, while resting between intervals, during time outs or half time breaks or during breaks at practice. Anytime you've been exerting yourself and you want to keep your effort level higher for longer, hold your AF Charge Bar.

Sanitize/Cleaning. We recommend cleaining your device in between uses by different people. The device (metal cylinder) and its color should hold up to any cleaner of your choice. We also recommend hand cleaning the rubber end caps, inside and out, with warm water and soap weekly.
Do not squeeze the bar too hard.You do not want to limit blood flow through your palm, you simply want to cool and and have it circulate back through your body
Do not get the bar too cold.If you use the AF Charge Bar when it's too cold you could trigger your blood vessels to constrict. This is because you're sending a signal to your nervous system that you are too cold and it will want to take measures to heat you up.
If your AF Charge Bar is getting too warm, just take off the cap and fill it with water from a water fountain or sink. The cool water will bring your bar back to a cool temperature rapidly.

We used our AVA Cooling Bars over the weekend at the Ontario Beach Volleyball Championships at Ashbridges Bay in Toronto. The temperatures soared to a scorching 41°C, but thanks to our Cooling Bars, we stayed comfortable between sets, during timeouts, and between games. They kept us cool and quickly became the envy of everyone around us! We’re spreading the word — everyone should experience AVA Cooling Bars!
I've been using this during PT to help reduce my HR in-between sets and to reduce body temp. My Fitbit is showing results already in less than a month. I've been hitting PBs and it's making PT much funner due to not feeling so sluggish afterwards or between sets. I love this and everyone asks about it. I got the blue 🔵 one. And I am so happy. Thank you so much. I really needed this.
Our softball players love this tool. Between innings our pitchers and catchers really like using it.
My son is elite bicycle athletics. This is best solution for tempering between hard trainings. Many thanks AVA!
We absolutely love our AVA! We work with many high level athletes teams, players and clients. Often time when they come out of their red light therapy their body temperature is high. We created a treatment called Fire & Ice. They use they as soon as they get out of the red light room & Viola.. It's an awesome experience. We love it!
Been using the AVA Cooling Technology device for a while now. Things I've noticed: It brings my heart rate down faster between intervals and I feel like I can get more high rep, difficult sets done on my higher volume training sessions. I like that it has a thermometer to tell me what the temperature is. It's also good that I can cool both hands with one device. I highly recommend this device.
Love these things... I live in Texas and workout daily... weight training and running/walking. Oftentimes it's extremely hot outside and these things keep me going. I use them between sets during exercise, between sets on sprint days, and I even use them when I'm working outside in the garage to keep my body temp stable... these are frickin' magic
It’s literally free progress! Too easy not to use.
WR Basketball loves the charge bar! We use our palm coolers in between pick up games to recharge. Our kids really like when the charge bar is used as a tool for refocusing them during stressful situations like a timeout in a big game. This is our secret weapon to increasing skill with more repetitions and staying ahead of our opponents in conditioning!
Been using AVA Cooling Technology with awesome results for myself and clients. I get it to 45 degrees and then use it intermittently throughout my workout and it wont get above 60 for almost an hour. If it does get too warm I just refill it with cold tap water. I've found a massive benefit from palm cooling when trying to fall asleep at night after a late trainig session. I had been too hot and aroused to calm down and sleep but then I started palm cooling on these nights and I fall asleep much more easily.
I am a personal trainer and have multiple AVA cooling devices. My clients LOVE and fight over them! In between exercises they look forward to their “chill” moments! My daughter also uses one during gymnastics practice in particular on bars. A fabulous product that is a must for any active individual!
I do NOT do well in the heat, and I train in crossfit at the highest level so a big factor is how you can regulate your temperature to maintain output. Any sort of interval training becomes exponentially easier with this between rounds. And after big long workouts, it really helps to bring things back to baseline. Can not say how highly I recommend this product!
Love using the cooling bars between sets. Never knew how much I'd love, and NEED them
Love it!! Have been using this after my workouts and before bed to help my recovery time. Definitely worth it!
Love my AVA Cooling bar! I used it in between sets on heavy lifts and is integral in optimizing my recovery! Seen big jumps in my output after using this device! Highly recommend!
I live in Louisiana and have a teenager who play tennis. This past weekend, in August, the air temp got up to 104° (heat index 111°) and this weekend was a yearly 3-day tournament-which is the main reason I bought this cooling implement (AVA). Keeping AVA the right temp in this heat, after use between sets, is a constant task. Refilling the water and adding ice, while storing in a cooler is a must. But- AVA helped keep my child from heatstroke. We saw three different teens fall to heat exhaustion, and one of them, whose overheating led to vomiting, I insisted try AVA as well (after he and their parents did not want him to forfeit). After holding AVA for 10 mins the AVA temp had increased over 20° -from 47° to 69°! He even went back to compete and win his match. For my child, we used AVA between side changes, sets, and matches and we saw no dips in overall function but honestly, that fourth match of the day at high noon was tough to stay in front of and I am sure we could not have done that without the addition of AVA in our cooling repertoire. Overall, I believe this device helps but is not a total substitute for other cooling tools in our toolbox.
2nd unit as the family of athletes growing bigger. Definitely helps with recovery to ensure consistent training.
Love the product! Thanks for everything!
Such a good device, simple yet practical and scientifically backed.
Great product, saw it at the NCAA Softball World Series and thought it would be great for my daughter.
Works great, especially for dead lifts and pull ups. The only issue is it sweats alot in the Louisiana humidity. It stays in the range for about thirty minutes.
Idea is good, but I expected the temperature to stay colder for longer. In warm weather it loses the appropriate temperature after 10 minutes.
From freezer to warm or inusable is only 45 minutes. Thought this would last longer for workouts. By the time i take it out of the freezer, deive to the gym and use it, i only get the benefit for 20-30 minutes.
Honestly I with it would sty cooler longer. I usually don’t make it through the big lifts begging of workout. I know I can add more cool water but I want to stop in the middle of working out. But I do feel recharged while using it
My trainer turned me on to palm cooling. It really helps on intense training days.
Tbh not sure if it works or is psychosomatic *but* my workouts are pretty good (along with nutrition, supplements etc) only annoying thing is I have to re-fill it a few times during a eorkout but thats a minor gripe.
bar does not hold cold temperature for much more than 20min once out from the fridge, on a 73F room, even filling it up with water does not lower temperature as suggested.
Honestly I don't think it did anything to improve my resistance training.
I haven’t used it too much just yet - busy with a newborn and the holidays. I look forward to testing it out and using it more consistently
Fantastic product!
It cools down way to quick for it to be effective, I had to fill if up 3-4 times during the workout for it to stay cold, and i ended up giving up towards the end because it stayed at room temperature
Fantastic product!
It feels quality, but when i use it in the gym it rapidly cools down not making it effective
Well, it works. The strength gains, at least for me, are solid, but not extraordinary. I’m not adding weight and reps like the Stanford studies showed, but when I use it, I feel like I’m having a “really strong” day in the gym. Worth it. As for AVA’s solution, pretty good, especially when comparing pricing to other products. I add water and then 10 cubes of ice to hit around 50 degrees. If rises to about 60 within 20 minutes, so it’s good to add some extra ice later to try to get it around 55.
It does feel like you are able to add more reps to your sets, like a fast recovery. Great purchase!
I purchased the cooling bar expecting it to be a great addition to workout routine but unfortunately it did not meet any of my expectations. The first issue was it didn't stay in the recommended temperature range very long after I precisely followed the instructions. Additionally, it didn't improve my stamina or speed up my recovery as claimed. Overall I wouldn't recommend the AVA cooling bar based on my experience.
Cool tech (no pun intended) works great in between heavy lifting sets.
This has moderately allowed me to increase the number of sets I can do on a single exercise. The bar is only cool enough for about 7-8 sets if you start at 45*. I suggest bringing a different water bottle with some ice in it to refill the bar if you want to use it on more than one exercise. Definitely need to rest at least 2+ mins between sets to see the difference. Would be nice if they added a timer on the end of the bar. Another use of the bar was to help fall asleep faster. Your body needs to cool down it's core temp before bed and this made a noticeable difference when I used it.
This bar was game changer. Super easy and convenient to use. Highly reccommend!
Good stuff
