Sagittal Plane Lunge

Sagittal Plane Lunge is an exercise used to target the muscles of the legs and glutes. It is an effective single leg movement exercise for improving strength, balance, and coordination. To perform it, stand with your feet about hip-width apart and take a giant step forward with your right leg. Plant your right foot firmly on the ground and bend both knees until your back knee reaches the ground. With your front knee bent and your back knee touching the ground, lower your hips

we're going to talk about a lunge, one of
00:00:0600:00:12
the last exercises, one of the hardest exercises in our lower body strength or
00:00:1200:00:17
resistance training progression. Now it falls so far within our progression because it
00:00:1700:00:21
requires a huge amount of stability and coordination as well as optimal extensibility of our
00:00:2100:00:27
lower leg and lumbo pelvic hip complex. So, an example of where a lunge would not
00:00:2700:00:32
be appropriate: if somebody has anterior pelvic tilt, or they have feet turn
00:00:3200:00:36
out a little bit in that overhead squat assessment, you're going to have to
00:00:3600:00:41
regress this exercise with either a step up, a squat, or a modified squat, while you
00:00:4100:00:45
work on that dysfunction, and then you can progress back to this exercise when
00:00:4500:00:51
they can get near optimal mechanics after their warm up. So I'm going to have Laura come
00:00:5100:00:56
in and help me demonstrate this exercise. And what we're going to try to do is
00:00:5600:01:00
match the lunge with all of the other lower body exercises we do as far as
00:01:0000:01:05
sports are concerned, it's really not that much different. So from the anterior view,
00:01:0500:01:08
from the front view, we just want to make sure the feet, knees, and hips are in
00:01:0800:01:13
a nice straight line, just like we would for a squat or a step up. I'm going to have Laura go ahead and step
00:01:1300:01:18
back into this lunge. Good. And she has nice alignment. We see feet, knees, and hips all in a
00:01:1800:01:23
straight line. The biggest dysfunction you would probably see is that
00:01:2300:01:28
in some people this back leg has a tendency to the veer out a little bit. If
00:01:2800:01:33
that happens one of two things is happening: either they're leaning back, or they still have some
00:01:3300:01:38
residual tightness in either the rectus femoris, or sometimes their TFL.
00:01:3800:01:41
You're going to have to go back and do a
00:01:4100:01:45
little bit of foam rolling and stretching, and then try this exercise
00:01:4500:01:49
again. Usually if you get somebody's rectus femoris loosened up they're going to
00:01:4900:01:55
lunge just fine. Go ahead and turn sideways for me. Now, from the side view,
00:01:5500:02:00
we still want a parallel line between tibia torso, and we want to make sure
00:02:0000:02:04
that we have a neutral alignment of the pelvis. So I'm going to have Laura go ahead and
00:02:0400:02:10
step back with this leg and back into the lunge, and as you can see she does the lunge that so
00:02:1000:02:17
many of us have been taught with back straight up and down. The problem with
00:02:1700:02:22
that lunge is if you put that back leg back, and then lean back, you're forced to
00:02:2200:02:27
to load this back. This back leg is in a stretched position, it's not in any
00:02:2700:02:29
sort of position that is going to be able to produce an optimal amount of
00:02:2900:02:35
force, and the idea behind the lunge is to try and strengthen that front leg. It's
00:02:3500:02:39
like a squat with a kickstand. To demonstrate this and I want to have Laura go down
00:02:3900:02:44
into a squat, just go straight down, there we go, and then I want you to shift
00:02:4400:02:50
your weight to this leg, good, and move this leg back. One-legged squat with a kickstand.
00:02:5000:02:55
All this is doing is stabilizing, we're trying to load this leg. Good and then
00:02:5500:03:00
come back up for me. Good. So when she goes back down I still
00:03:0000:03:04
want this back leg straight up and down. I get people to think of a merry-go-round
00:03:0400:03:07
horse, that have the poles through the center of them. This should go straight
00:03:0700:03:13
up and down, but, we noticed that Laura still has this straight up and down back too. What I
00:03:1300:03:19
usually do with an individual like this is have them reach. As she goes down I'm going to have her
00:03:1900:03:25
reach with the opposite hand of the foot that's forward. Good. We get a little bit
00:03:2500:03:30
of a forward bend there. Now we have our hip flexion, her glutes stretched out, so it's
00:03:3000:03:33
loaded knowing that I'm going to get her glute to fire on the way back up.
00:03:3300:03:41
Go ahead and come back up, perfect. Back down, good. Are you starting to feel it in the front leg? -Oh yeah!
00:03:4100:03:45
Usually you start getting people do this, and I understand it's a little excessive of a forward
00:03:4500:03:49
lean at this point, but it's teaching her the proper mechanics, so we're going to
00:03:4900:03:53
go ahead and start here. Now, with Laura, this this is probably where I would stay. If I were going to
00:03:5300:03:57
progress with a strength progression I'd just add some dumbbells, from a stability
00:03:5700:04:02
progression I might add an Airex pad, or some other piece of balance of equipment in front of this
00:04:0200:04:07
front foot. Once I got her to do proper mechanics, there are a
00:04:0700:04:12
couple of ways to progress this saggittal plane static lunge. So go ahead just start standing
00:04:1200:04:17
straight up. The first progression we can utilize, you have probably heard of is
00:04:1700:04:23
a reverse lunge. So let's go ahead and go down into a reverse lunge, good and back up.
00:04:2300:04:27
You can see Laura still has that straight up lunge, so what I want you to do is when
00:04:2700:04:31
you're doing that reverse lunge still use the forward touch. Good. Get back up with
00:04:3100:04:37
this right glute. Good. Down, tell people to thrust forward with their hips as they
00:04:3700:04:41
come back up to get that right glute, and you can see her reverse lunge looks pretty good as long as
00:04:4100:04:45
she does this queue. If I wanted to increase the stability I can have her go from
00:04:4500:04:51
reverse lunge to balance, and then to balance she's not going to put this leg back
00:04:5100:04:57
down. The only place this leg's going to touch is behind. If she really had back down I
00:04:5700:05:02
could then put a piece of balance equipment under this right foot. Now, a
00:05:0200:05:08
progression for this would be the standard front lunge. The reason a front lunge is
00:05:0800:05:13
harder than a back lunge, is in a reverse lunge the foot that is
00:05:1300:05:17
decelerating, or slowing her down on the way down is still on the floor. In the front
00:05:1700:05:22
lunge she's going to build up momentum that she then has to decelerate with that
00:05:2200:05:28
front leg. So go ahead and back up a little bit for me. Alright, let's see your front lunge.
00:05:2800:05:32
There's a little bit impact there. Good, take a little further step, I still want you to reach forward.
00:05:3500:05:39
You can see that her
00:05:3900:05:45
back leg is still going straight up and down. So a reverse lunge would be good for Laura,
00:05:4500:05:49
this is probably a little tough. We could then do a front lunge to balance, just
00:05:4900:05:54
like we did on the previous exercise. You could then go ahead and add stability
00:05:5400:05:58
equipment here. It's pretty rare that I get somebody to be able to do a front lunge to
00:05:5800:06:02
balance on a piece of stability equipment, that would be tough. If we wanted to add weight you
00:06:0200:06:06
could definitely do that. If it were in a strength training program of course we
00:06:0600:06:10
could do walking lunges at a little faster tempo, if we were more in a power training
00:06:1000:06:14
program and working towards a little bit more speed. I hope the queues that I just gave
00:06:1400:06:19
you help you out. I hope you feel your front leg when doing lunges. I'll
