Mobility for Lifters: The Three Restrictions That Actually Matter

If you train seriously and your squat depth, overhead position or hinge is limited by range rather than strength, general mobility work is an inefficient way to fix it. Identifying which restriction is actually responsible, and working on that, is much faster.

Three restrictions account for the overwhelming majority of cases.

Ankle dorsiflexion

What it limits: squat depth, front squat and overhead squat positions, lunges.

How to test: kneel in front of a wall with one foot flat, and see how far back the foot can be while the knee still touches the wall with the heel down. Around ten centimetres is a reasonable benchmark. Compare sides. Asymmetry is common and informative, especially after an old ankle sprain.

What to do: loaded dorsiflexion work, knee driving forward over the toes with the heel down, under some load, for repetitions rather than long holds. Calf length work supports it. This is one of the faster-responding restrictions.

Hip range

What it limits: squat depth, hinge quality, and the point at which the pelvis tucks under at the bottom of a squat.

The hip is more complicated than the ankle because part of the limit may be bony. Hip socket depth and femoral neck angle vary substantially between people, and they determine how deep and how wide a squat can be. Someone whose squat stops at a certain depth with a firm, blocky end feel may have reached bone, and no amount of stretching changes that. The answer there is to adjust stance width and foot angle to find the position that suits your anatomy.

What to do: work hip flexion with external rotation, hip extension in half-kneeling, and adductor length. Then test stance variations and keep the one that lets you reach depth without tucking.

Thoracic extension and rotation

What it limits: overhead position, front rack, and bench setup. It is also the most common restriction in people who sit a lot, which is most people who lift.

A lifter who cannot extend the upper back will compensate by arching the lower back to get the arms overhead. That is the mechanism behind a lot of lower back complaints in people who press.

How to test: sit on the floor with your back against a wall, legs out, and raise your arms overhead keeping the lower back in contact with the wall. If the arms will not reach the wall without the ribs flaring, this is your restriction.

What to do: extension over a rolled towel across the mid-back, side-lying rotation, and overhead work done with the ribs deliberately down.

The rule that matters more than any of it

Range without strength in that range does not transfer to the bar. If you gain depth in a stretch and then never load it, the body treats it as irrelevant and gives it back.

So every mobility gain should be followed by loading the new position, a paused squat at the new depth, an overhead hold in the new position, a hinge through the new range. That step is the difference between mobility work that changes your lifts and mobility work that changes how you feel on the mat.

When to do it

Before training: movement through range, five minutes, no long holds.

After training or separately: the actual range work, held longer, warm.

Once a week: a longer session covering rotation, single-leg control and slow work that your programme does not include.

Where a teacher helps

Working out which of the three is limiting a given lift is harder than it sounds from inside your own body, and people routinely work on the wrong one for months. Somebody watching a squat from the side resolves it in about a minute.

Sessions are live on video, thirty or sixty minutes, and a first session is a sensible place to sort this out.

Questions people ask

What limits squat depth most often?

Ankle dorsiflexion and hip range, and for some people the limit is the shape of the hip joint rather than soft tissue. A firm, blocky end feel suggests bone, in which case adjusting stance width and foot angle is more productive than stretching.

Should I do mobility work before or after lifting?

Movement through mid-range before, held length work after or in a separate session. Long static stretches immediately before heavy work slightly reduce force production for a short period.

Why do I lose mobility gains?

Because range that is never loaded is not retained. Follow any gain with work that loads the new position (a paused rep at the new depth, an overhead hold) or the body treats the range as unnecessary.

Does a tight upper back affect my overhead press?

Frequently. If the thoracic spine will not extend, the lower back arches to get the arms overhead instead, which is a common source of back complaints in people who press. The wall test will tell you quickly.
