My Experience
15 years experience in different work field

I am used to a hard drill. I was a professional soldier for many years. My favourite place at all the military bases I went through was always a gym. I have been training for more than 15 years. Sometimes was hard because I was so busy and didn't care much about my body and health in general. I realized that health, whether physical or mental, is the most precious thing we have in our lives. So here I'm. Your healthy life guide.
