Missed muscles in lower body

[Brookfine]

Hey Rip,

Background: I have a pulled Adductor Longus which triggers sharp pain when it is used. Despite this I have been able to squat, row, power-clean, and deadlift with no issues. This leads me to believe that the Adductor Longus isn't worked at all by these movements, and has me wondering if there are actually many muscles in my lower body that the program doesn't work at all.

Ask: Is there some kind of movement (or collection of movements) I can be doing to fill these gaps? I'm a sprinter and it's important for my sport that there are no weak-points as this can cause injury. I'm very concerned about my adductors and my hip flexors.

Thanks Rip!

Let's examine this issue. What does the adductor longus do? Origin/insertion/action?
