TUESDAY DEEP DIVE: THE STRETCH
Sunday’s issue introduced the Side-Lying Quad and Hip Flexor Stretch as this week’s foundational movement. Today we go deeper.
Hip flexor tightness is almost universal in adults over 60 — the result of decades of sitting, reduced daily movement range, and training patterns that favor the front of the body over the back. But not everyone arrives at this stretch with the same mobility restrictions, the same floor comfort, or the same baseline flexibility.
The three variations below address the full spectrum. Start where the description sounds like you, not where you think you should be.
Better than your last ED “solution”
Most ED meds handle blood flow. That's only half the job. Rugiet Ready™ is a 3-in-1 sublingual treatment that targets your brain and your body—because great sex starts with arousal, not just circulation.
Just drop it under your tongue and Rugiet Ready™ works in as little as 15 minutes and lasts up to 36 hours. No pills to swallow, no planning your night around pill timing.
Over 400,000 men have already made the switch and the reviews are borderline inappropriate (in a good way).
Try Rugiet Ready™ and find out what your body's actually capable of.
VARIATION 1: SUPINE HIP FLEXOR STRETCH (BEGINNER / LIMITED FLOOR MOBILITY)
Best for: People who find side-lying positions uncomfortable, those with shoulder or neck issues that make supported side-lying difficult, or anyone just starting to address hip flexor tightness.
How to do it:
Lie on your back on a mat, near the edge of a bed or a firm surface
Draw both knees to your chest, then let one leg lower toward the floor, keeping it as straight as comfortable
Hold the opposite knee pulled toward your chest — this anchors the pelvis and prevents the lower back from arching
Let gravity do the work on the lowered leg; the stretch is felt along the front of the hip and upper thigh
Hold 30–40 seconds per side, 2 rounds
What you’re feeling: A gentle pull along the front of the hip and the top of the thigh. If you feel pinching in the groin or front of the hip socket, draw the leg slightly inward.
Progression cue: When the lowered leg easily reaches the floor or near it without arching the lower back, you’re ready for Variation 2.
VARIATION 2: SIDE-LYING QUAD AND HIP FLEXOR STRETCH (INTERMEDIATE)
Best for: Most people. Good floor comfort, moderate hip flexor tightness, able to maintain hip stacking without the pelvis rolling back.
How to do it:
Lie on your side on a mat, hips stacked directly on top of each other
Bend your top knee and hold the ankle or the top of the foot behind you
Gently pull the heel toward your glutes while keeping your hips stacked and your lower back in neutral — not arched
The stretch should be felt along the front of the top thigh, not in the lower back
Hold 35–45 seconds, roll over, and repeat on the other side
2 rounds each side
What you’re feeling: A stretch along the rectus femoris (the quad muscle that also crosses the hip joint) and the hip flexors below the hip crease. The side-lying position keeps the pelvis neutral in a way that standing versions of this stretch rarely achieve.
Common error: Letting the hip roll backward to reach the foot. If you can’t hold the foot without the hip tilting, use a strap or a towel looped around the ankle. The hip position matters more than the depth of the stretch.
VARIATION 3: HALF-KNEELING HIP FLEXOR STRETCH WITH POSTERIOR PELVIC TILT (ADVANCED)
Best for: People who move regularly, have reasonable knee comfort on the floor, and want to address not just tissue length but the neural component of hip flexor restriction.
How to do it:
Kneel on one knee on a mat with a folded towel under the knee for comfort
Step the other foot forward so the front knee is at roughly 90 degrees
Before shifting forward, tuck the pelvis posteriorly — gently squeeze the glute of the kneeling leg and tilt the pelvis backward, flattening the lower back
Maintaining that posterior tilt, slowly shift your weight forward until you feel the stretch deep in the front of the kneeling hip
Raise the arm on the kneeling side overhead and lean gently away from it for an additional lateral stretch along the hip flexor and oblique
Hold 40–50 seconds per side, 2 rounds
What you’re feeling: A significantly deeper stretch than the lying variations, reaching the iliopsoas at its origin near the lumbar spine rather than just the rectus femoris. The posterior pelvic tilt is the key — without it, the lumbar spine simply extends and the stretch never reaches the deeper tissue.
Why it matters for bone density: This variation is the most direct preparation for loaded hip extension exercises like the sumo deadlift from Sunday’s issue. When the iliopsoas can fully lengthen, the glutes can fully activate, and the hip extension that drives bone-loading force during deadlifts becomes complete rather than compensated.
Stop These 6 Lash Mistakes
Thinner lashes after 50 aren’t “just aging”
It is also the way you're taking care of them...expired mascara, waterproof formulas, heated curlers, harsh preservatives, and more.
This page breaks down 6 things to stop today + what to use instead for lift without irritation. Read the lash tips.
HOW TO USE THESE VARIATIONS
You do not need all three in the same session. Choose the one that best matches your current mobility and spend your time there. As restriction decreases, progress to the next level.
A practical weekly approach:
Use Variation 1 or 2 as a morning mobility routine — it takes less than three minutes and starts the day with the hip flexors in a lengthened position rather than the shortened one they wake up in.
Use Variation 2 or 3 before any lower-body strength session, particularly before deadlift or squat patterns.
Use Variation 3 as a dedicated mobility session when hip flexor restriction is limiting your training range of motion.
ONE MORE THING
Hip flexor length is one variable. Hip flexor neural inhibition is another. Sometimes the tissue has adequate length but the nervous system is still guarding — keeping the muscle contracted as a protective reflex rather than a structural limitation.
If you find that your stretch depth varies dramatically from day to day despite consistent practice, this is likely what’s happening. It responds well to slow, non-aggressive stretching combined with the glute activation work from Sunday’s strength move. The two together signal to the nervous system that it’s safe to let the hip flexor lengthen.
COMING UP
Thursday we go deeper on the strength side: three progressions of the deadlift pattern from Sunday, ranging from the complete beginner to someone ready to add meaningful load. Same fundamental movement, three different entry points.
