Customer Experiences

This is incredible… I saw measurable increases in my work volume before technical failure (2 extra sets of any exercise beyond the 5 I typically do) and a subjective (but real) delayed onset of fatigue when cooling between sets.

Brazilian Jiu Jitsu Competitor

The strength gains were incredible. I cooled between my high intensity sets. When I started the cycle my max squat was 405 pounds, and when I finished I could do 5 reps of 405.

CrossFit Gym Owner/Competitor

All my use in training has been awesome. If I am doing conditioning for a prescribed yardage, I feel I can hold a higher percentage of my speed for more reps

When it comes to training strategies, CoolMitt is one of, if not the best I have used. Truly It is one of the few things that I see that legitimately makes a difference. After 2 months... i can't believe I am doing 30lbs more on a rep I have been stuck doing for 3 years.

Powerlifter/Football Player

It definitely works.

I have to admit that I was quite doubtful and expected to not see much or any improvement. But, I was really surprised at how much difference it made. What was before an RPE (rate of perceived exertion) of 10 is now an RPE of 8 with only 30 sec of cooling.


When I started training with CoolMitt between sets of lifting and intervals on the bike, I achieved measurable higher power output and significantly faster times in time trials.

World Champion Senior Track Cyclist

After three weeks of training with CoolMitt, I achieved over a 5% increase in threshold power. 

Former Tour de France Cyclist

When using during long training rides on a stationary bike, I am able to push for longer without fatigue.

Ironman Champion

During training with CoolMitt, the pitchers were able to maintain top velocities of fastball as well as breaking pitches throughout each set. It is not unusual to see drops of .5-2mph drops at this point of off-season training. The pitchers also exhibited better command, and consistency in their areas of analytical specialty (spin rates, vertical and horizontal break, spin efficiency) in pitching sessions.

CoolMitt is a game changer

Increased my 1 rep max bench press by 40lbs in 2.5 months


Overall this summer I found the CoolMitt to be very productive in my training. I got stronger and it allowed me to be more revitalized during my sets, particularly my upper body workouts.

NCAA Baseball Player

I’ve added 40 pounds to my split squat in the past month doing the same number of reps. And I’ve used the CoolMitt between high-cadence sprints where I normally get leg pump, and I noticed that while my legs still do get pumped, it takes much longer.

Pro BMX Racer

Really Amazing

After I received my CoolMitt, I decided to see how much it would help. I did a baseline test of 6 sets of pushups to failure, with a 3 minute rest in between. My performance on the baseline was 43 pushups the first set, 21 on the second and I plateaued at 14 the last few sets. 3 days later I did the same workout, but used CoolMitt during my 3 minutes rests between sets. This time I did 44 on the first set. The second set I did 34 reps, and I plateaued at 24. I was able to do 50-60% more reps on the cooling day.
