A balanced runner will do better: strength, mobility and symmetry

Running is a series of single-leg hops. Every stride loads one side of your body at a time, so small imbalances repeat thousands of times a run. Balance — in strength, in training and even in how you carry your kit — is what keeps you running.

Strength: two short sessions a week

Twenty minutes, twice a week, is enough to make a difference. Focus on single-leg work:

• Split squats or step-ups — 3 × 8–10 per leg
• Single-leg Romanian deadlift — 3 × 8 per leg
• Calf raises (straight and bent knee) — 3 × 15
• Side plank — 3 × 30 seconds per side
• Glute bridge, progressing to single-leg — 3 × 12

Mobility: little and often

Five minutes of hip, ankle and thoracic mobility before a run beats an hour of stretching once a month. Leg swings, ankle rocks against a wall and open-book rotations are a good start.

Balance your training week

Mix easy runs, one quality session and one longer run. Avoid stacking hard days back-to-back.

Carry your kit symmetrically

This one is overlooked. A heavy phone in one hand or strapped to one arm adds a small, constant asymmetry to your arm swing. A waist pack with everything on one side can rotate your hips. A central chest vest keeps weight on your midline, which is why I prefer one. See the full comparison of carriers.

Listen to niggles early

A niggle that changes how you run is a reason to back off for a few days. Two easy days now beats two weeks off later.
