TESTOSTERONE : tutte le informazioni sul testosterone Testosterone : l'ormone maschile per eccellenza. Leggere anche l'articolo relativo all'impotenza. Il testosterone è un ormone steroide del gruppo androgeno prodotto soprattutto dalle cellule di Leydig nei testicoli e, in minima parte, il testosterone è sintetizzato nella corteccia surrenale. È presente anche nella donna, ma come prodotto intermedio nella sintesi degli estrogeni. Contribuisce a garantire la fertilità, in quanto agisce sulla maturazione degli spermatozoi nei testicoli. Secondo gli scienziati il livello di testosterone cala anno dopo anno. Così hanno ad esempio scoperto i medici autori del Massachussetts Male Aging Study (pubblicato dal Journal of Clinical Endocrinology and Metabolism), osservando che ultimamente, ogni anno sparisce dall'organismo maschile circa l'1.2% del testosterone, l'ormone che caratterizza la mascolinità.

Strength Training 101: How to Squat Properly This is an article by NF Team Member Staci. Squat squat squat squat squat squat squat squat squat squat squat…. Everybody! Wait, that’s not right… But that’s what I hear, because I love squats. Why?

Not only that, but it mimics a ton of natural movement patterns in everyday life. Whether your goal is to gain strength or lose weight, squats are one of the fastest ways to get there. If you’ve never squatted before, you might be a bit intimidated about the idea of starting a big new exercise. Squats are a big part of the Nerd Fitness Academy, and today we want to give you the confidence you need to START. Why squat? Squats are one of the most foundational functional movements in our lives. In some countries, not only do they continue to sit in a full squat (sometimes called a “third world squat”), but instead of sitting on a toilet, they squat over it.
