Alex Zinchenko is a strength addict, coach, and the author of the Rough Strength blog, where he shares his crazy ideas regarding training and nutrition. He is honest to toothache, straightforward like a train, and too daring to believe that heavy calisthenics, kettlebell, and sandbag training along with intermittent fasting can deliver all the results you want.
