Pottstown Boxing Club

PAC Boxers, get ready; we are introducing 2 benchmark workouts that will be recorded for you to gauge your athletic performance. These benchmark trainings are going to be short and intense, and you will track them on your handheld devices - this is the science behind this "Threshold Training" that will have skills transferable to your Boxing Craft.

"The Why": In the CrossFit methodology, neuroendocrine adaptation refers to a neurological or hormonal change in the body. Greg Glassman championed the idea that high-intensity compound movements trigger significant systemic responses—such as increases in testosterone, human growth hormone (HGH), and insulin-like growth factor (IGF-1)—that drive dramatic athletic and physiological improvements. Glassman argued that isolating muscles (e.g., bicep curls) invokes virtually no neuroendocrine response. Instead, to maximize hormonal adaptation, athletes should focus on compound movements, utilizing multi-joint exercises like squats and deadlifts that recruit large muscle groups. High intensity: Pushing physical limits with short rest intervals and varied, high heart-rate protocols.Measurable results: Using heavy loads and functional movements to mimic the beneficial hormonal changes of exogenous therapy (like steroid use) without the negative side effects. This hormonal surge is why these specific training regimens rapidly increase muscle mass, bone density, and overall fitness.
