I’ll use a paused front squat as my assistance in the beginning, with a weekly progression looking like this,
Week 1: 5-8 second eccentric
Week 2: 5-8 second eccentric with 3 sec pause at midrange of eccentric motion
Week 3: 5-8 second eccentric with 3 sec pause at midrange of concentric motion
Week 4: 5-8 second eccentric with 3 sec pause at midrange of eccentric motion and another 3 sec pause at midrange of concentric motion
To drill that motor pattern.
