Upright, relaxed posture
Your head stays level and your shoulders stay low through the whole stride. In frames 3 to 9 there is a straight line from ear to hip with a slight lean from the ankles.
More kilometres build fitness. Better form makes every kilometre cost less. Film yourself from the side and see what you do well, what to fix first, and a drill for each fix.
Filming tip: Film from the side, phone at hip height, 3 to 5 m away, camera still. A treadmill is ideal. 10 to 20 seconds of steady running.

The easy 5%
Fitness takes months of kilometres. How you move, you can change this week. And it pays off on every single step you take.
Bouncing up and down, or braking with a foot that lands far in front of you, burns energy that doesn't move you forward. Cleaner form puts more of every step into going forward.
Energy you stop wasting is energy you can spend on pace, or on holding your pace for longer. No extra training hours needed.
Some patterns, like overstriding, are often linked to knee and shin trouble. Landing closer under your hips spreads the load more evenly.
What the pros do
Elite runners and their coaches use motion analysis to find small changes in how they move. Until now that meant a lab, special cameras and an appointment. Motionlab gives you the same kind of look with the phone in your pocket.
In a lab
With Motionlab
10 to 20 seconds from the side. A friend or a steady shelf does the job.
Your video stays on your phone. We only look at a few still frames.
What you do well, what to fix first, and a drill for each fix.
A short summary, then your two biggest strengths and the two things to fix first. Every point shows the frame it comes from, and every fix comes with a drill you can start this week.
Your posture is a real strength: tall and relaxed. The one thing to work on first is where your foot lands.
Your head stays level and your shoulders stay low through the whole stride. In frames 3 to 9 there is a straight line from ear to hip with a slight lean from the ankles.
In frames 4 and 11 your heel touches down well in front of your body with an almost straight knee. That brakes you a little on every step and loads the knee.
Drill
Wall drill march
3 × 30 s
Lean into a wall with straight arms. Drive one knee up, then put that foot down under your hip, not in front. Switch legs with a steady rhythm.
Why runners trust it
We look at a few still frames and don't store them. No account needed.
No vague “great form”. Each finding points to the frame where you can see it yourself.
If something looks like an injury risk, we tell you to see a physiotherapist. We never guess.
Nobody. It stays on your phone. We only send a few still frames for the analysis and don't store them.
A phone, and someone or something to hold it steady.
That depends on where you start. Form changes take a few weeks of regular drills before they feel natural. Film again after three or four weeks and compare.
No. Coaching feedback only. If something hurts, see a professional.
