You may want to pay attention.
You need symmetrical psoas muscle activity to pull you down into a symmetrical squat.
You also need your psoas during the swing phase of running to possibly reduce impact forces and loading rate (Schmitz et al, 2014).
What's wrong with this front squat position?
As it goes, I can actively adjust to line the hips up in this position, but it's not a natural position and I definitely don't maintain it.
When I squat under load, or deadlift, or pistol squat, I have a sensation of discomfort in the right lower back - same side as the hip that isn't flexing as much as the other side.
What do you think could be the reason?
Let's look at 2nd one - can I get as much flexion as the other side, passively? This video shows that I can.
Now watch what happens when I use "core activation" to assist active hip flexion.
That core activating will improve psoas activity gives me a corrective exercise.
To progress that, I resist the pattern of hip flexion, such as I did with this track sprinter in China.
Then I add core-assisted squatting, such as I did with this handball athlete from China.
