When a well-known YouTube fitness personality puts your product to the test—especially in a video titled “Fitness Products With Outrageous Claims”—you hold your breath.
But when that test turns into a glowing recommendation?
You celebrate!
Recently, Will Tennyson, a popular fitness influencer with over 3.8 million subscribers, reviewed the AF Charge Bar by AVA Cooling Technology as part of his exploration into unconventional performance tools. What started with a dose of skepticism quickly turned into genuine surprise and praise.
“This thing is actually great... my work capacity went up like crazy. Constant good energy and strength the entire time. Definitely going to be using it again.” — Will Tennyson
In the video, Will highlights the science behind palm cooling—specifically how cooling the hands between sets can reduce local fatigue, regulate body temperature, and allow for greater training volume. He references studies where subjects using palm cooling outperformed even steroid-using counterparts in terms of strength endurance.
What He Found:
- Increased Reps: He added 3 reps per set during a heavy dumbbell workout.
-
Faster Recovery: He reported “no lactic acid burn,” even during high-rep supersets.
-
More Energy: Each set felt “like my first set of the day.”
-
Real Results: Will described the experience as having “endless stamina” and said he was “definitely going to be using it again.”
