Tibialis Anterior Isolated Activation (No Equipment)

Tibialis Anterior Isolated Activation (No Equipment) is an effective exercise for strengthening the front of the lower leg muscles (tibialis anterior) and improving ankle stability. This exercise can be done at home with no equipment or at the gym with the use of resistance bands. It is an important exercise for injury prevention as well as performance and agility enhancement. It requires exaggerated dorsiflexion movements of the ankle and focus on maintaining proper form and alignment. This exercise

This is Brent of the Brookbush Institute, and in this video we're going to go over a

00:00:0700:00:11
variation of tibialis anterior activation that requires no equipment.
00:00:1100:00:15
Now this isn't my favorite variation, I prefer the previous video we showed
00:00:1500:00:19
where we had a monster band around a treatment table, or a monster band hooked
00:00:1900:00:22
to something heavy and you were in long sit on the floor. That external
00:00:2200:00:27
resistance becomes real handy and you can get that recruitment pattern of heel
00:00:2700:00:33
strike, but I understand that those monster bands can be hard to hook up if
00:00:3300:00:36
you don't have a treatment table, if you don't have something really heavy to
00:00:3600:00:41
hook up to, if you don't have room behind that heavy object to hook up to that you
00:00:4100:00:46
can actually get in long sit position, you're kind of out of luck. So this idea
00:00:4600:00:50
of having a variation where you don't need equipment, that becomes very handy
00:00:5000:00:56
for things like home exercise programs, for group exercise classes and for team
00:00:5600:00:59
training where you're trying to do a little movement prep. Obviously tibialis
00:00:5900:01:03
anterior activation is going to help get some inversion, help fight against pes-
00:01:0300:01:07
planus, or feet flat during an overhead squat assessment, which we know is going to
00:01:0700:01:10
be beneficial for all of our athletes. I'm going to have Melissa come in, she's
00:01:1000:01:14
going to help me demonstrate. Melissa does have a little lower extremity
00:01:1400:01:20
dysfunction. Alright, she definitely works with some stuff in her ankles and she
00:01:2000:01:23
can get a little flat-footed from her running and what-not. She's going to get in
00:01:2300:01:27
plank position on the wall here to start. it is important to kind of be leaning
00:01:2700:01:32
against the wall, we want stability. We don't want to make somebody have to try
00:01:3200:01:36
to balance or stabilize because I want to be able to focus on getting some
00:01:3600:01:43
activity in my tibialis anterior. Now the cueing is the same. I need her to dorsiflex
00:01:4300:01:46
and invert to get her tibialis anterior drive up, but I also need to
00:01:4600:01:51
her to reciprocally inhibit her overactive synergist, being her long toe
00:01:5100:01:55
extensors, especially her extensor digitorum longus which is not only in
00:01:5500:02:00
dorsiflexor, but an eva durand pronator of the foot. So it can really really
00:02:0000:02:06
contribute to that flat-footed-ness. So what she's going to do is she's going to
00:02:0600:02:11
try to get into as much dorsiflexion as she possibly can, by driving the this
00:02:1100:02:17
big toe knuckle right her first MTP up as high as she possibly can. That'll
00:02:1700:02:20
that'll get her thinking about dorsiflexion and inversion, and then
00:02:2000:02:28
she's going to curl her toes at the same time to try to shutdown extensor
00:02:2800:02:32
digitorum longus (EDL). Now you can see here Melissa is having a hard time with her
00:02:3200:02:36
dorsiflexion. So we're doing this barefooted only
00:02:3600:02:41
because we want you to be able to see her toes, but you could technically put
00:02:4100:02:45
something under her heels and have her put her shoes on as you probably
00:02:4500:02:49
would in a group environment anyway. What you put your heels on could just be a
00:02:4900:02:52
couple weight plates that are around. Alright and now she's going to have some
00:02:5200:02:57
room to actually get some dorsiflexion. A good thing for you guys to watch out for
00:02:5700:03:02
is if the person can't get their fifth metatarsal or the lateral side of their
00:03:0200:03:05
foot off the floor, they probably need a little heel rise to make this really
00:03:0500:03:14
effective. Now the reason this isn't my favorite variation is effectiveness on
00:03:1400:03:19
this exercise, actually getting some observable objective outcomes like let's
00:03:1900:03:25
say an improvement in dorsiflexion goniometry is 100% dependent on Melissa's
00:03:2500:03:30
effort. So if she just goes through the motions and just flops
00:03:3000:03:33
her foot up and then back down, show them that flop foot up back down, just flop
00:03:3300:03:37
foot up back down, she just kind of does this thing then you're not you not
00:03:3700:03:44
getting any results. But if she really really tries to get in as much
00:03:4400:03:49
dorsiflexion as she possibly can and hold it with toes curled, I know she's
00:03:4900:03:54
going to activate the heck out of her tibialis anterior, and the reason being
00:03:5400:04:01
is she's working against her overactive calf complex. So as long as she puts
00:04:0100:04:06
in effort, she really tries to get to the end of dorsiflexion, I know she's going
00:04:0600:04:12
have to work against her own resistance here. How's that going? We
00:04:1200:04:16
usually have to go a little drill-sergeant at this point -so up, hold
00:04:1600:04:22
two three four, squeeze and back down. Right I'll do like two-four-two count
00:04:2200:04:29
right and one of my favorite tempos for activation exercise -hold three four back
00:04:2900:04:36
down, come on up. Let's go for some sexy shins because everybody wants sexy shins, back
00:04:3600:04:42
down, up, hold. Now if she gets really good at this maybe I've had a couple
00:04:4200:04:45
sessions with her, you have had a couple group training sessions where
00:04:4500:04:47
everybody knows what they're doing, you can do both feet at once.
00:04:4700:04:52
So we can dorsiflex on both sides once they get a handle on it,
00:04:5200:04:57
kind of cut our time in half for this particular exercise. Hold, squeeze as hard
00:04:5700:05:04
as you possibly can. Good up -two, three, four. I don't see the
00:05:0400:05:08
lateral side of your foot high enough come on. I mean how are you going to have
00:05:0800:05:14
sexy sexy shins if you don't, that's what everybody wants right I heard that sexy
00:05:1400:05:19
shins were in this year. Alright back up good and then back down. Now the way
00:05:1900:05:24
your ankles set up your tibia isn't at the end of your foot, so if you
00:05:2400:05:28
dorsiflex it's not like this where your tibia wouldn't move, your
00:05:2800:05:32
activity is actually a bit forward kind of in the middle-ish of your foot, the
00:05:3200:05:35
middle third of your foot. So when you dorsiflex your calcaneus actually goes
00:05:3500:05:40
down and you end up lifting up your whole body-weight, which means that if
00:05:4000:05:45
you do one foot at a time it's actually really hard. Alright so I'm going to have
00:05:4500:05:48
her lift this leg, you will be able to see the dorsiflexion and inversion on
00:05:4800:05:54
this side as she struggles, which she is definitely struggling. Melissa you got to
00:05:5400:05:58
work on this. Obviously this would be a little easier for her if we maybe did a
00:05:5800:06:04
little bit more mobility work to start off with. We you know release her calf,
00:06:0400:06:10
mobilize her ankle, stretch her calf and then do this stuff. But with that being
00:06:1000:06:13
said you guys can see how this variation doesn't require much equipment. It's
00:06:1300:06:18
fairly easy to coach right, you can just once they get foot up and in with toes
00:06:1800:06:22
curled, you know you can kind of queue a bunch of people through that once, and
00:06:2200:06:26
then the nice thing is that we can go straight into our reactive activation
00:06:2600:06:30
which is that heel walk video I have up. Alright and we can even gamify that in
00:06:3000:06:36
a group and do what we call penguin walk marathon, where you get heel walks
00:06:3600:06:41
and you time it and see who can walk the longest. Alright so have a little fun
00:06:4100:06:44
that way and it all starts of course with this,
00:06:4400:06:50
and of course it took no equipment. Again it doesn't get the same effect that I
00:06:5000:06:55
get out of something like the tibialis anterior activation that's resisted, but
00:06:5500:07:00
it does get me some pretty good results. Obviously it comes in handy,
00:07:0000:07:05
obviously for home exercises it's perfect, and I'd really like to see a
00:07:0500:07:09
little bit more corrective exercise than our in our group environments. So if you
00:07:0900:07:12
guys have any questions, if you have any comments please leave them in the box
00:07:1200:07:17
below. I look forward to seeing a lot more of this out in the field and in
