admin2026-02-17T15:14:06-05:00At the ARMory we study OUTLIERS so my players can become THAT GUY! While science seeks to find common denominators among the normal, it propagates “The Cult of Average.” Average is a code word for mediocre, and that is not our goal at The Florida Baseball ARMory.
Anatomy Of A Pitcher’s Hip Hinge: First Move Nuance
admin2021-04-16T17:40:54-04:00A well-executed one-legged hinge is vital to increasing impulse and improving velocity. But, not all hinges are the same. The single-leg hinge must be nuanced to link the athlete’s hardware to his software. This requires an in-depth investigation and appreciation of each athlete’s unique physical characteristics and movement preferences.
Anatomy Of Hip-To-Shoulder Separation
admin2021-11-03T05:32:04-04:00Unless you’ve been living in the baseball equivalent of a Himalayan monastery, you’ve heard pitching and hitting coaches avowing the importance of “hip-to-shoulder separation.” I’m not exactly sure when it began, but sometime in the last several years, someone coined the term, and it spread like wildfire. According to advocates of this tenet, pitchers and hitters should rotate the pelvis while the torso remains closed for as long as possible. The resultant diagonal stretch through the trunk allows the athlete to take advantage of the elastic properties of the abdominals, and chest muscles to store and then unload energy to be transferred from the lower half to the arm or bat.
