Jumping isn’t just a test—it’s a snapshot of your body’s true power. Vertical, broad, and lateral jumps reveal how strong, fast, and coordinated you really are. After 40, they’re more than metrics—they’re signs of how well you’re aging athletically. 🧠💥 Ready to see what your jump says about you?

You’re training hard, eating smart—but your body just isn’t playing along like it used to. Welcome to midlife chemistry. In this sixth chapter of “The Prerequisites for Strength”, we explore the endocrine system: the hormonal command center quietly dictating your recovery, performance, energy, and body composition. As we age, the rules change—but the game isn’t over. You just need a new playbook. 🧱🧬⚖️

You can lift mountains, but if your engine sputters, the whole system fails. In the fifth chapter of “The Prerequisites for Strength”, we tackle the often-overlooked foundation of strength: your cardiovascular system. It fuels your lifts, feeds your muscles, and determines whether you recover or burn out. Even the biggest deadlift depends on a healthy heart. After 40, this isn’t optional—it’s essential. 🧱❤️🏋️‍♂️
