Mobility

Joint access between sessions. Mobility → Structural Work → Running Mechanics

Start with the reset below. If something feels restricted during running, come back to the relevant section.

5-minute reset

Mobility does not need to be long. A few movements keep the joints open between sessions.

Running loads a small chain of joints repeatedly. These five areas are the ones that restrict mechanics when they tighten.

Hip Flexors

Running shortens the hip flexors. Restoring length allows the leg to travel fully behind the body.

Kneeling Hip Flexor Stretch 60–90 sec each side

Drop to one knee. Back knee on the ground, front foot forward. Drive the hips forward until the front of the back hip opens. Torso tall.

Signal: stretch in the front of the hip, not the lower back. If the back arches, tuck the pelvis slightly.
Couch Stretch 60–90 sec each side · post-run

Back foot elevated on a wall or couch, front foot forward on the floor. Hold upright. Start with 30 seconds and build. Hip flexor and quad release together.

Signal: length in the front of the hip. If the elevated knee is painful, lower the angle.
Ankles

Ankle mobility controls foot placement and the forward lean. Restriction here shows up in both.

Ankle Circles 10 slow circles each direction, each ankle

Seated or standing. Rotate through the full range slowly. Notice where it catches or resists — that is what you are loosening.

Signal: movement from the ankle, not the knee. If one direction is tighter, spend more time there.
Calf Raise to Stretch 10 slow raises then 30 sec hang · both legs then single leg

Rise slowly onto the balls of the feet, then lower below the step level. The raise activates, the hang loosens.

Signal: the calf lengthens at the bottom. If the Achilles is tender, skip the single-leg version.
Calves and Achilles

The calf complex absorbs landing forces on every stride. It loads more heavily from Week 3 onward.

Standing Calf Stretch 45 sec each side · straight knee then bent knee

Hands on a wall, one foot back, heel flat. Straight knee targets the upper calf. Bend the back knee slightly to shift into the Achilles. Both positions matter.

Signal: tension in the calf, not sharp pain in the Achilles. After Week 3, add a second round of the bent-knee version.
Foot Rolling 60 sec each foot · post-run

Stand on a lacrosse ball. Roll slowly through the arch and heel. Pause on tight spots for 5 to 10 seconds. The plantar fascia connects into the calf chain.

Signal: the foot softens under pressure. If the foot is acutely sore, skip this.
Mid-Back

Mid-back mobility supports posture and arm mechanics. When it stiffens, the lower back compensates.

Extension over Foam Roller 8–10 extensions · 2–3 segments · post-run

Foam roller across the mid-back. Arms crossed. Let the upper back extend gently over the roller. Move up one segment at a time. Do not roll the lower back.

Signal: movement in the upper back, not the lower back.
Seated Rotation 8 slow rotations each side · any time

Seated, feet flat. Arms crossed over the chest. Rotate from the mid-back — not the hips or lower back. If the hips move, the rotation is coming from the wrong place.

Signal: rotation in the upper back. Restriction here shows up as a shoulder drift during the run.
Glutes
Clamshells 15–20 reps each side · slow

Lie on one side, hips stacked, knees bent at 90 degrees. Feet together — open the top knee without the hips rolling back. Pause at the top.

Signal: glutes working, not lower back. If one side is weaker, that hip is not contributing fully during running.
Glute Bridge 10–15 reps · 2 sec hold · both legs then single leg

On your back, knees bent, feet flat. Drive the hips up by squeezing the glutes — not the lower back. Hold. Lower slowly.

Signal: glutes working, hamstrings quiet. If the hamstrings cramp, press the feet into the floor more and focus the squeeze higher.

When
Before running Ankles and hips. 3 to 5 minutes. Prepares the joints before Ghost sessions and easy runs.
After running Hip flexors and calves. While warm. Useful after threshold and long runs.
Rest days Full sequence. Take time with the holds. Pairs well with Structural Work sessions.
Week 3 onward Add daily calf and Achilles work. The spring sessions load them heavily.
Mobility work should remain small enough
that it never feels like a second session.
