This is Brent, President of B2C, looking
00:00:0300:00:07
at the second exercise in our relative flexibility
00:00:0700:00:11
progression for back strength and nervous system training program.
00:00:1100:00:15
We've now increased mobility and stability just a little bit,
00:00:1500:00:19
we can move from saggital plane exercises to saggital overhead and frontal plane exercises.
00:00:1900:00:24
I'm going to have Mike come in and help me demonstrate our pull up progression.
00:00:2400:00:29
So, our five kinetic chain checkpoints remain the same.
00:00:2900:00:35
Now, Mike go ahead and step on - well first, grab the handles and then step onto the assistance here.
00:00:3500:00:40
Make sure he's all lined up, feet completely parallel, hip width, his knees and hips line
00:00:4100:00:46
I'm going to have him make sure he still reinforces his triple extension mechanics, squeezes his
00:00:4600:00:50
glutes, locks out his knees, and pushes down with his feet.
00:00:5000:00:56
He's going to draw in and tuck under for me, and then as he pulls up, as many well know,
00:00:5600:01:00
it would be very questionable for him to pull behind his head, there's no reason to do that,
00:01:0000:01:05
the lats have a line of pull anterior to posterior, so I'm going to have him think
00:01:0500:01:11
about pulling up toward his chest, so let's go ahead and see that happen.
00:01:1100:01:13
Now, the chain is important.
00:01:1300:01:18
The bad things that could happen at this point that we often see are his back will start
00:01:1800:01:23
to arch on the way down, so we just have to keep reminding him to tuck under and squeeze his glutes.
00:01:2300:01:28
The other thing we'll see is, on the way down - let me have you do one more -
00:01:2800:01:33
on the way down he'll lose stability of their scapula and move into elevation.
00:01:3300:01:36
We don't want to see that so, let me go ahead and see that Mike.
00:01:3600:01:41
Lower your shoulder blades, his shoulders are near his ears.
00:01:4100:01:46
Another compensation you might see is, as he pulls up he goes into protraction,
00:01:4600:01:49
anterior tipping and shoulders end up near his ears.
00:01:4900:01:51
A lot of people do that sort of thing. All of these things are bad.
00:01:5100:01:56
We don't want to have him reinforce this upper body dysfunction,
00:01:5600:02:00
we want him to maintain scapular depression and retraction both on
00:02:0000:02:10
the way up and on the way down. So let's go ahead and see that.
00:02:1000:02:13
Now we started with a frontal plane pull up here, if he didn't quite have enough
00:02:1300:02:16
mobility and stability to maintain perfect form here
00:02:1600:02:26
we could regress this from a relative flexibilty standpoint by going to the inner handles.
00:02:2600:02:34
The same things apply. Depression, and retraction. If I wanted to increase the stability on this
00:02:3400:02:40
assisted machine I can have him just lift one leg.
00:02:4000:02:44
Go ahead and go up. Believe it or not, this really does reduce stability.
00:02:4400:02:48
Now, a huge progression involves stability and strength,
00:02:4800:02:50
would be to have to have no assistance whatsoever.
00:02:5000:02:56
Or maybe you could even go to a band for assistance, rather than the solid assistance offered by the machine.
