WIM HOF AKA ICEMAN, his story and discovery is the huge inspiration for me, it literally made me stripped off my cloth in the -10 degree, after taking several deep breath, stretching and jumping, I start to feel warm and so much energy in my body, sometime the idea sounds inane but it actually works.
I do believe this method could be every effective for improve stamina, increase energy level and treat many chronic issue, especially you are the person who gets cold easily it will be very helpful for you.
If you interested you can also download his app in the apple store by just search WIM HOF METHOD
