Why does my hip hurt during lunges

Front of the hip pinching is often just tight hip flexors

If the pain sits right at the crease where your leg meets your torso, and it shows up more on the trailing leg in a lunge, that's classic tight hip flexor territory. Sitting all day at a desk shortens that muscle, and then you ask it to stretch under load during a lunge. It complains.

This isn't damage, it's just a muscle that's rarely asked to lengthen. A few weeks of consistent stretching and mobility work usually eases it off without changing anything else in your routine.

Deep ache on the side could be a mobility or stability issue

If it's more on the outside of the hip or feels like a deep ache rather than a pinch, it can be your glutes not firing well to control the movement. Lunges ask one leg to stabilize while the other moves, and if your hip stabilizers are lazy, the joint takes on load it's not built to handle alone.

This shows up more in guys who mostly do squats and deadlifts and never touch single-leg work. Your hips just aren't used to the demand yet.

• Try standing hip CARs before your session to wake the joint up
• Add banded lateral walks a couple times a week to build hip stability
• Regress to a shorter range split squat before going back to full lunges

Check your setup before you blame your hips

Sometimes it's not your hips at all, it's your stance. Lunging with your feet on an imaginary tightrope, one directly in front of the other, twists the hip in a way that can cause pinching. Give yourself a little width, like walking on train tracks instead of a rope.

Step length matters too. If your step forward or back is too short, you end up folding at the hip more than you need to. Lengthen the step slightly and see if that changes anything.

Build the range back gradually

Don't just avoid lunges and hope it fixes itself. That usually means the hip stays tight and the problem shows up again the next time you try. Better to work backward: mobility drills first, then a shallow, controlled lunge variation, then full depth once it feels clean.

The 90/90 hip switch is one of the better drills for this because it trains rotation and control at the same time, which is exactly what a lunge demands from the hip joint.

When to actually worry

A little tightness or dull ache that eases up as you warm up is normal and not a red flag. What's worth paying attention to is pain that's sharp, that radiates down the leg, or that sticks around for days after your session. That's when you stop guessing and get it looked at by a professional instead of trying to stretch your way through it.
