Bar Path Lab: The Line the Bar Should Travel
Pick a lift, then let the bar drift. Watch the red path pull away from the ideal line and see how much longer the lever gets at your hips or shoulders.
Plain-English concept
Close to the body, over mid-foot, is the efficient line.
Your balance point is the middle of your foot. When the bar stays stacked over it, you stay balanced and the weight takes the shortest route.
When the bar drifts forward, the horizontal distance from your working joint to the bar — the lever — gets longer. The weight hasn't changed, but the work at your hips, back, or shoulders has.
Interactive model
Let the bar drift and watch the lever grow.
The dashed grey line is the ideal path; the solid red line is the path with drift. Scrub the rep to see where the drift hurts most.

The red line is the hip lever: the horizontal distance from the joint to the bar. Longer lever, more work for the same weight.

Coach takeaways
Keep the bar where it belongs.
Small drift, big cost
A few centimetres off the line can add a surprising amount of work at the hips or shoulders.
Film from the side
A side-on phone video is the easiest way to see your own bar path.
Fix the cause
Drift usually comes from a dropping chest, loose lats, or pressing out front. Fix that and the path follows.
