Emphasis should be placed on the glute max and Hamstring for hip extension and Glute Med to keep pelvis level. Many will cheat with the LB and this can and will affect individuals with pelvic instability and LBP in a adverse way. Maintaining a post pelvic tilt is the key to locking the SI and inhibiting LB overuse.

Just a word of caution for the less experienced; be cautious when performing with anyone presenting with SI join† instability or active LBP. The shearing force of a unilateral leg extension may be adequate to cause inflammation or worse. You could modify with unilateral heel lifts or toe lifts to maintain a psuedo-closeed chain exercise. You will see the dysfunction in a less dramatic, but safer movement assessment. I am sure Bob would address this given more time than a 2 minute video affords; can't wait to read his research article- I am sure it will be very enlightening and well worth the read. The Pilates advanced mat exercise called "Shoulder Bridge" adds unilateral leg extension with hip flexion and extension from this same position, with arms to ceiling to take away arm support. Very difficult, but it would add a strength, flexibility, and endurance component Ron may appreciate, especially when 10 reps are performed with each leg, perfectly of course. Just make sure you are advanced in practice. It is true that mm. activation (motor skills) may influence this movement; some clients will drop the hip because they do not know the glute med. needs to hold strong on the standing leg and others could not hold it for their lives because it isn't functioning. Too much prolonged static sitting, side to side misalignment in standing posture and same side habitual leg crossing in our computerized society. And Katie, I'm sure you are holding position (neutral pelvis) correctly as you work up to 60 seconds-form leads to function. Thanks Bob, as always your information is first rate and cutting edge. Look forward to your next video and glad to have a referral resource in Las Vegas; many of my golfing clients visit your area regularly and you know how important core/glutes are to golf swings.

Does this exercise work to strengthen or create muscle endurance? I am with you that it's important for good core stability and strength but wonder how big the ceiling is in terms of strength increases due to the limited way resistance can be added. My vote is this is more an activation and endurance exercise rather then pure strength. I do use it when I train all my athletes.
