Hi, this is Brent, President of B2C Fitness, and we're going to demonstrate

plank progressions and regressions.
00:00:0900:00:11
I'm going to have Vinnie come in and help us demonstrate.
00:00:1100:00:16
First thing we do with any of our exercises is we align our kinetic chain check points.
00:00:1600:00:19
So we're going to make sure that the head is back, and chin is tucked.
00:00:1900:00:22
We're going to make sure Vinnie's arms here are parallel to each other.
00:00:2200:00:27
So right now, he's kind of internally rotated, we're going to make sure his shoulders are stable,
00:00:2700:00:30
and that he's not rounding his back. We're going to make sure he's drawn-in,
00:00:3000:00:33
his glutes are tight, and his knees are locked.
00:00:3300:00:35
Also, that we have his hips knees and feet aligned, which they are.
00:00:3500:00:41
I'm going to have Vinnie take one more step here, and tuck his toes as far underneath him as he can,
00:00:4100:00:44
so hopefully he's getting the balls of his feet to touch the floor.
00:00:4400:00:49
And then to increase the type of stabilization we're going to get here,
00:00:4900:00:51
we're going to get here in his core, out of this plank
00:00:5100:00:57
I'm going to have him use his glutes to drive his feet through the floor as if he's digging holes in sand with the balls of his feet.
00:00:5700:01:03
So this our standard plank, working all of the anterior musculature of our spine,
00:01:0300:01:08
as well as working on the glute stabilization of our hips.
00:01:0800:01:13
We can regress this exercise very simply by just dropping down to the knees.
00:01:1300:01:21
Once again, mind the same queuing. So we want to draw-in, glutes tight, driving the knees into the floor,
00:01:2100:01:24
the toes are still tucked in. We can also progress this exercise very simply by going back up to the toes
00:01:2400:01:29
and having him go to one leg.
00:01:2900:01:34
Now be very careful, if you do this progression, that there's no tilting this way,
00:01:3500:01:41
that we still have the glute drive through the floor on the leg that is on the ground, that's the important leg.
