Generally, biceps exercises are set up so the upper arms remain roughly parallel to the torso and the resistance reduces as the hands get closer to the chest. But the guillotine curl requires the upper arms to be positioned perpendicular to the torso with the shoulders flexed (arms forward with respect to the torso). That makes the resistance grow stronger – instead of decreasing – as the cable moves downward toward the body.
This is a great finisher exercise when training biceps. Hold and squeeze the biceps at the peak contraction to further heighten the training effect.
Nate Miyaki says to forget the resolutions, forget the endless string of magical diet and training tips; all you need to do is learn one simple lesson.
Within the realm of training for greater strength, muscle mass, and endurance lies an area of science that remains relatively untapped: Neuroscience. It's indeed the uncharted waters in the vast ocean of the science and practice of resistance training. That's because so little is known about how the nervous system actually works.
