Once you have you ingrained the hip hinge movement and have mastered it with simple motions (without extra weight), Then I would strengthen it with some of these exercises.

Exercises to do to warm up: Prying Goblet Squat, Hip (glute) Bridge, Halo, 90/90 stretch, QL stretch.  Videos of these exercises are here: Video page

• Kettlebells(KB) swings (Russian)

This is a great exercise because it is strictly a hip hinge motion done repetitively and will build up strength along the posterior muscle chain.

• Deadlift (barbell and KB).  Key, control the kettlebell, don’t let the KB control you.  

You may here that this exercise is a bad one to do because so many people hurt their back when doing it.  Only half of the statement is true. Many people do hurt their back when doing it, but it is not a bad exercise, in fact it’s one of the better ones and here is why. Many people do get hurt because 1) they haven’t mastered the hip hinge and use more of there back to lift the weight instead of their hips. 2) People will add too much weight too soon, they are not ready for the extra weight. When you go to lift the extra 10 lbs of weight, the first thing the is going to leave you is your form, because your goal is to lift the weight and you don’t care how to do it because you want to reach your PR.  3) People will perform too many reps and sets. Same principle applies as #2, when you want to reach the certain number of reps and/or sets but you aren’t ready for it yet, the first think that will be sacrificed is your hip hinge form.

• Single leg deadlift (KB)

Do it unilaterally do focus on one side at a time.  

• Squat (barbell and KB)

Get your legs into it.
