All protocols

Set an evening alarm to help begin winding down and support the transition into sleep.

A daytime nap can improve motor skill learning versus staying awake, showing the benefit is due to sleep rather than nighttime itself.

Avoid cutting off the final part of sleep, because stage 2 sleep and sleep spindles in the last quarter of the night are especially linked to motor memory benefit.

Presented as a foundational dietary basic before fine-tuning with supplements or other interventions.

If sleep tracking causes sleep-related anxiety, avoid checking it daily; either review data only once weekly, such as Sunday afternoon, or stop using the tracker temporarily, restore sleep confidence, and only then return to using it.

Delay phone use for at least the first 30 minutes after waking to avoid eclipsing sleep-derived creative insights with external sensory input.

Capture ideas that emerge after waking by writing them down; suggested as a way to preserve sleep-derived creative insights.

If you have severe or persistent back pain, get a proper assessment and diagnosis from a qualified back expert; if non-surgical methods fail, consult a surgeon.

If you have a thicker, less mobile spine, emphasize work aimed at generating more flexibility in side-to-side and angled planes of motion.

Especially if you have back pain or posterior disc bulging/herniation, avoid sit-ups and abdominal crunches because they can worsen disc bulging, nerve impingement, and pain.

McGill Big Three exercise: Lie on your back with one knee bent and the other leg extended, place both hands under the lower back to preserve its arch, keep the head neutral with the tongue on the roof of the mouth, and breathe through the nose. Lift the elbows and upper chest only 5–10 degrees by leading with the chest, not the chin, contract the abdominals for 8–10 seconds, rest 10–30 seconds between reps, then switch sides; a typical routine is 3–5 sets with descending holds (5, 4, 3, 2, 1 reps), done daily or 1–2 times per week.

Aim to do the Big Three at least once or twice per week; some people may do them daily. Even 1–2 sets of each can be completed in 5–10 minutes.

If any movement worsens your back pain, stop doing it.

Hold onto a sturdy overhead bar or object with arms overhead while keeping toes, feet, or heels in contact with the floor so it is not a full dead hang; avoid twisting; aim to lengthen the spine for 10–30 seconds, walk around, then repeat 2–3 times.

Avoid inversion practices if you have glaucoma or are predisposed to glaucoma because inversion increases ocular pressure.

For posterior disc bulge-type pain: lie face down with hips in contact with the floor, toes pointed back, legs straight and together, head neutral; press up like a push-up while keeping hips on the floor. Do 8–10 repetitions and hold the final rep until you begin to quake slightly, then relax. Used to encourage the disc bulge back toward the center.

If pain is too severe for cobra push-ups, stand about 6 inches or so from a wall with hands on the wall and push the hips toward the wall; can be progressed later to floor cobra/up-dog style work.

Place fists under the jaw on either side of the chin; with tongue on roof of mouth and breathing through the nose, press the chin downward against the resistance of the fists for a 10-second static contraction. Do 3–4 repetitions of 10-second contractions for 2–5 sets.

Use shoes with a wider toe box; host notes benefiting from a slightly wider toe box shoe for running.

Shoes with individual toe compartments are mentioned as an option some people use, including for running.

Practice spreading the toes apart on both feet so none are touching; this can take a couple of weeks to learn. While sitting barefoot with toes spread, practice lifting toes independently, starting with lifting the big toes independently of the others. As a no-purchase aid, place firm paper towel or tissue between the toes to help learn toe spreading. Advanced option: strengthen individual toes with bands.

When at rest, relax the abdominal musculature and belly breathe: inhale so the belly moves out, exhale so the belly moves in.

Use a mirror to help ensure the belly button stays facing forward during staggered-stance anti-rotation resistance work.

When seated and during daily activities, especially if prone to posterior disc bulging or low-to-mid back pain, avoid rounding the lower back; keep it straight or slightly arched, but not overly arched.

Lie on your side as if preparing for a side plank but keep the lower leg on the floor; point the top foot's toe downward, bring that foot slightly in front to touch the floor, then extend the heel back toward the back wall and slightly toward the ceiling while maintaining the downward-pointed toe. Do 5–10 repetitions, then hold the final raised position for 10–20 seconds. Repeat on both sides. You can press into the top of the working-side glute with your thumb to feel it activate. May be repeated a couple of times per day if needed for pain relief, and can also be used as a leg-day warm-up.

Recommended posterior chain exercise for strengthening the back and posterior chain and maintaining power and posture with age.

Specialized equipment needed to perform glute-ham raises.

Take a long lunge with one leg back and the other forward; raise the arm on the same side as the back leg overhead; turn the palm parallel to the ceiling/sky and rotate so the pinky turns toward the head. Hold 5–10 seconds while breathing normally, then switch sides. Intended to stretch the psoas and create a sense of spinal lengthening/open hips.

If you have shoulder or back tightness, make sure you do enough pulling exercises to balance pushing exercises like pushups, shoulder presses, and bench presses.

Weekly structure of 3 resistance training sessions, 3 cardiovascular training sessions, and 1 complete rest day; intended as a sustainable minimum-effective schedule. Resistance work can be organized as legs, torso, and arms/small body parts.
