CONTEST PREP UNIVERSITY - FRAT HOUSE SERIES #2: Refeeds And Calorie Modulation 24.02.2022 31:55
Do we need higher-calorie days? Should they be different pre-contest or off-season? What do they do? How much higher? What food sources? In one meal or divided through the day?

THE MIND-MUSCLE CONNECTION - Ep 11: CIVILITY 04.02.2022 23:58
Every generation thinks the world is going to end. Ours is no different. And, this time it might. But not really. We're just living out the growing pains of social media and nonstop information. Our amygdalas are tired. The worst part about our current hyper-sensitivity and intolerance? We isolate instead of engage. We stop learning and exploring. Our brains atrophy... and that means our health, n...
THE MIND MUSCLE CONNECTION - Ep 10: Personal vs. Public Health 28.01.2022 26:04

THE MIND MUSCLE CONNECTION - Ep 9: Binary Thinking 21.01.2022 21:21
The more you believe something, the greater the chance that you're deceived by your own emotional tie to the topic. Every bit of information that flows into our brains causes a cascade of binary triggers. Threat/non-threat... good/bad... safe/unsafe... right/wrong... true/untrue... and those are just the initial value judgments. The doorway for those thoughts then channel our memories, emotions, a...
