What Your Hips Have To Do With Your Back Pain
Most rowing-related back pain doesn’t start in the back — it starts with limited hip flexion that forces the lumbar spine to do a job it was never built for.
Ask most athletes where rowing back pain comes from and they’ll point at the back. The research points somewhere else first: the hips.
The mobility number that matters
The range of a rower’s hip flexion should be at least 130 degrees, the knee range of motion should be full, the hamstrings should have good flexibility, and the trunk muscles — particularly the back and buttock muscles — should have good endurance to reduce the risk of back pain. That 130-degree figure isn’t arbitrary. It’s roughly the hip flexion needed to reach a strong catch position without asking the lower back to compensate.
When hip flexion falls short of that, the body still has to get the torso forward to reach the catch — it just borrows the range from somewhere else. In rowers with restricted hip flexion, the pelvis tends to tilt back, which loads the lower back more. The spine ends up flexing to make up the difference the hips couldn’t provide, stroke after stroke, for the entire session.
A test you can run on yourself
A related test is going from sitting to standing off a low step — a flat lower back and relaxed upper body through that movement correlates closely with an athlete’s ability to connect through the hips at a rowing catch, rather than compensating with the lower back.
What to actually do about it
- 01Train the range, not just the stroke. Hip mobility work off the machine — deep squats, hip flexor and hamstring work — pays off directly in how the catch position holds up under fatigue.
- 02Don’t chase depth you don’t have. Reaching for a longer catch than your hip mobility supports just transfers the missing range to your spine.
- 03Build trunk endurance, not just trunk strength. Endurance of the back and glute muscles is what keeps the spine in a protected position for an entire piece, not just the first ten strokes.
Fixing a rowing back-pain habit by focusing only on “keep your back straight” cues addresses the symptom. Addressing hip mobility addresses why the back was rounding in the first place.
