Build Muscle, Great Posture & Resilience to Injury | Jeff Cavaliere

Jeff explains that chronic low-back pain often results from a progressive chain: weak glute medius → pelvic drop → lumbar paraspinal spasm. The spasm is the body’s attempt to artificially stabilize the area. Releasing it restores movement, but the underlying weakness remains. He therefore pairs this release with the wall hip slide and banded rotation exercises. Huberman calls this protocol life-changing, stating it eliminated his decade-long back pain.

Jeff emphasizes that every step you take involves a slight pelvic drop. People with weak glutes exhibit an exaggerated drop that forces the spinal erectors to spasm. By strengthening the glute medius, you restore normal gait mechanics and offload the spine. He notes that even strong athletes can fail rotational hip strength tests, proving that big lifts don’t automatically train these small muscles.

Jeff notes that reverse hypers are easy to do anywhere (even on the edge of a bed) and that most people are so weak in the glutes that bodyweight is challenging. He stresses holding the top contraction to “convince yourself that you actually performed the movement.” This exercise, combined with the hip slide, addresses both sagittal and frontal plane hip stability.

Jeff details how modern posture (texting, typing) chronically shortens internal rotators, so even raising the arm to wash hair can cause impingement over time. He shows progressions: from neutral to stepping away, then jumping laterally to mimic ballistic needs. He emphasizes that internal rotation is not evil but must be controlled by adequate eccentric external rotation strength.

Jeff notes that neck training is the most overlooked yet highest payoff investment. He observes that women often avoid it for fear of getting a thick neck, but the muscles involved don’t hypertrophy dramatically, especially if traps aren’t directly overloaded. Huberman shares that he attributes his lack of whiplash after a car accident to years of neck training.

Jeff explains that even he experiences a back twinge sometimes during this test, illustrating how sensitive it is to any weakness. He frames it as a mini workout for the stabilizers, and insists that sitting down to put on shoes is a form of seeking “easy,” which accelerates aging. The test is trainable; with practice, most people improve rapidly.

Huberman credits this drill (learned from Jeff’s videos) with creating rock-solid lower-back and hip stability, which translated to breaking plateaus in squats and deadlifts. Jeff explains that the faster and quieter the weight, the better the control.

Jeff explains that the glute medius controls hip adduction and pelvic level. When it’s weak or in spasm, the pelvis tilts, and the lumbar spine must adapt, causing chronic overload. The spasm is a protective response to a weak area. He walks through the self-release: lie on your side, top leg bent in front, toe down, and raise the leg up and back while pressing the tender spot. He stresses that this is a temporary fix; one must then strengthen the glute medius with exercises like the “hip slide up the wall” (stand next to a wall, drop the hip, then slide it back up using the outer hip) and banded hip rotation drills to prevent the problem from returning.

Jeff analyzes the physiology: lumbar paraspinals must control forward trunk lean, ankles and knees continuously adjust to perturbations, and the glute medius maintains pelvic level during single-leg stance. He shares that even he occasionally tweaks his back simply bending to put on a sock, illustrating the test’s sensitivity. The test is not a one-time evaluation but a skill that improves with practice — “if it’s trainable, it’s fixable.” He urges against the easy path of sitting down to put on shoes, because “if you seek easy, you’re going to get old a lot faster.”

He illustrates a typical scenario: after reading to his boys and accidentally falling asleep, he wakes at 10-11 p.m., heads to his home gym with low energy, and tackles the non-strength movements (lateral raises, hip hugger) that night, leaving the heavy pressing or leg work for the following night. This “splitting the split” reduces psychological load, lets him ease into the session, and has left his joints feeling better while strength continues to rise despite suboptimal sleep. His training week can stretch to 9-12 days. He now questions rigid frequency prescriptions, emphasizing consistency and listening to the body.

He explains that improved general strength — squats, deadlifts, core work — increases torque generation, arm strength, and stability that automatically carry over to the sport, even without direct mimicry. For instance, a pitcher’s throwing velocity benefits from core stability, not just arm training. He advises adding small-specific work like forearm exercises if needed, but the majority of gym time should be devoted to bilateral, balanced strengthening. This approach also counters the imbalances that repetitive sport motions create.

Jeff reinforces that every muscle in the body has a function, and ignoring the small ones is illogical if longevity means maintaining ability. He advocates finding efficient ways to incorporate them into existing workouts — such as the towel scrunch for feet, band rotations for hips, neck plates, and grip-focused pull-ups — and notes that individual decay rates call for personalized supplementary routines. This dovetails with his own flat feet and knee problems that could have been mitigated by earlier foot training.
