Running has to be the worst sport out of all: > not fun at all > destroys joints > no meaningful goal > extremely stressful > makes you low T > ages you fast > gives you skinny fat physique > inefficent to lose weight

The healthiest habit in America is quietly destroying millions of knees. Walking 15,000 steps a day builds your heart, your lungs, your endurance. It also loads the same five muscle groups in the same direction, 5.5 million repetitions per year, while the muscles responsible for keeping your knees from collapsing inward barely fire at all. Your body moves in three planes. Sagittal (forward and back), frontal (side to side), and transverse (rotation). Walking is almost entirely sagittal. Quads, hamstrings, glutes, calves: all getting hammered. Your adductors, the five muscles along your inner thigh, work in the frontal plane. They stabilize the pelvis, keep the knees tracking straight, and prevent the femur from drifting into varus alignment under load. During level walking, they activate at a fraction of their capacity. Along for the ride. Run that imbalance for a decade. The outer thigh gets progressively stronger. The inner thigh stays the same or atrophies. The knee joint, caught between two muscle groups pulling in opposite directions, starts absorbing asymmetric force with every single step. Cartilage wears unevenly. The medial compartment takes the hit first. This is how knee osteoarthritis develops. Knee OA now affects roughly 23% of the global adult population. In the US alone, surgeons perform nearly 800,000 total knee replacements per year at $30,000 to $50,000 each. That number is projected to hit 3.5 million annually by 2030. Patients with knee OA show 8 to 24% weaker hip abductor and adductor muscles compared to healthy controls. A longitudinal cohort study found that weaker hip muscles predicted faster OA progression. When the NHL gave players with weak adductors a 6-week strengthening program, injury rates dropped from 3.2 to 0.71 per 1,000 game exposures. 78% reduction from targeting one muscle group. The doctor telling this person’s dad to walk less is treating the symptom. The imbalance is the disease. Copenhagen planks, lateral lunges, side-lying adductions. Fifteen minutes, twice a week. That’s the difference between a $40,000 surgery and a body that can actually handle its own mileage.

Load Management: When I talk about load management in the office, I can see the moment it lands the wrong way. People often hear “don’t do too much.” They hear restriction, caution, and many hear weakness. That is not what I intended. Load management is not about doing less. It is about doing the right amount — and then building from there. Tendons do not heal because we protect them indefinitely. They adapt because we challenge them. But they adapt on their timeline, not ours. When the load exceeds the capacity, they breakdown and become painful. When load is too low for too long, their capacity shrinks and they’re more susceptible to overuse injury. The sweet spot lives in between. That middle ground is not avoidance. It is progressive exposure. If your Achilles hurts, the answer is rarely “stop moving.” It is also rarely “push through it.” It should almost never be put in a boot! The answer is to adjust the load so the tendon can tolerate it, then gradually increase that demand. That might mean temporarily reducing volume, slowing down tempo work, or modifying range. Think of it like strength training. You do not walk into a gym and deadlift your lifetime goal on day one. You pick a weight you can manage, stress the system, recover, and come back slightly stronger. Tendons are no different. The stimulus has to be enough to matter, but not so much that it overwhelms your ability to recover. What I am trying to teach when I talk about load management is durability. It is the skill of matching stress to capacity and then expanding capacity over time. That requires honesty about where you are today, not where you were ten years ago or where you wish you were. In midlife, especially, recovery becomes the governor. Aging is associated with a higher price for intensity and longer recovery time frames. Cardiovascular systems adapt quickly. Connective tissues adapt slowly. If we ignore that reality, pain becomes the teacher instead. Load management is not about shrinking your world. It is about expanding it safely. It is the difference between repeatedly flaring the same tendon for years and building the kind of resilience that lets you run, lift, hike, and play for decades. The goal is never to do less. The goal is to build the capacity to do more.
