Make sure your training also has plenty of movement into all the end ranges of the body during the warm up and that it has carries, single arm carries, side planks, regular planks, and stir the pot (look it up from Stu McGill). You can’t just mobilize and expect it to go away and or go away and never come back.

They are absolutely connected. If the Thoracic becomes extremely kyphotic many times we will see an exaggerated lordosis. The body will make lots of compensations so you can continue to see straight ahead. Glad to hear you are making changes in a positive way!

I will echo Kaitlin here. See someone who can guide you to a solution and not someone who is just looking to see you over and over again. We can not diagnose a problem over a forum. 

Step one, make your feet symmetrical, bring the heel of the right foot behind your toes more so it straightens that foot out a bit. Step two, get your hands all the way around the bar and don’t let your wrists flop back so much. Step three, actively rotate your elbow pits up to the sky a bit, you don’t have to exaggerate external rotation but you are going to need a bit more than you are displaying her. Step 4, practice from the bottom up, have someone hand you a bar in the bottom and help you into position and then hold for a few seconds and stand up. You can also lie on your back on the ground and get yourself into the bottom position against a wall and hold the bar overhead in the snatch grip for some breathing and end range loaded mobilizing. 

As a general statement they should try to walk with their feet fairly straight ahead. The most important part is they need to understand how to keep a strong arched and flexible foot. When people turn their feet way out whether it be fore some anatomical issue or not they tend to destroy their feet because they are not working in a favorable position. If someone focuses on it over time there is no reason to think their body won’t adapt. Time is the biggest factor. 

Not every person on earth is going to end up looking exactly like Kelly when he squats no matter how much time they spend mobilizing. If it hurts your knees to have your feet that straight then turn them out a little. We have been very clear at MWOD there is a window between straight ahead and about 15 degrees of turnout where you can still get the most hip strength and power. The important part is don’t let your feet collapse and or ankles collapse in. Focus hard on that and just squat as deep as you can. Surely look over the book and work on limitations in the ankle and the hip but don’t also get caught up in wanting to look exactly like someone else.

You have to start by maintaining a very stable arch in the foot. Your foot collapses and your hip and knee come in. I start all people I see with these types of movement issues with box squats and only going as low as you can while maintaining a stable arch in the foot and the knee tracks over the 4th and 5th toe. You have been given new range and have no control. It is a process but that is the best place to start.
