Los pull-ups parecen un movimiento tan básico, pero para algunos, levantar la barbilla sobre una barra, incluso una vez, parece imposible. ¿Lo que da?
You might assume strong arms are all it takes to complete a successful pull-up, but the movement is much more complicated. When you’re hoisting your whole body up, you’ll also need a strong back, butt, core, and more. Without a strong core, for instance, bad form will make it even harder to work against gravity. You’re creating even more resistance than you would be if you were in a good vertical position where your legs, hips, and feet were all in alignment
