Enter the TUBOW

(A Blast from the Past article originally posted on 11/20/18)

What on earth is a TUBOW?
So glad you asked! A TUBOW is a Terribly Useful Block Of Wood. Many of you have seen us use 2-foot lengths of 4 x 4 lumber when people squat from time to time - these are TUBOWs.

Why would one use a TUBOW?
We use TUBOWs in the squat, and there are a couple reasons we might use a TUBOW. The most common use is to fix the knee's forward position on the way down.

becky’s knees are so far forward that parker refuses to watch.

Two common errors that we see when people squat is either (a) the lifter's knees travel forward all the way down, or (b) the knees travel forward at the bottom of the squat.

We would like to see the knee establish its final forward position about 1/3 to 1/2 of the way into the descent of the squat, and touching the TUBOW with the knee at this point provides excellent tactile feedback as to whether or not the lifter is doing that correctly. If the lifter accidentally knocks the TUBOW over, it provides excellent negative feedback that the knee has traveled too far forward.

becky touches her knees lightly to the tubow during the descent.

Another use of the TUBOW is to fix the knee's lateral position in the squat, i.e., is the lifter shoving the knees out (to the side) far enough, or perhaps even too far? The TUBOW gives the lifter something concrete (well, lumber, actually) to aim for, and very often, this will help solve the issue.

One of the great side effects of fixing the knee position is that it will often fix the back angle in the squat as well. If the lifter's knees can only travel "so far" forward on the descent, then the hips will have to travel backward (since your hips and knees are connected by your femurs . . . you know . . . the leg bone). If the hips have to travel backward, the lifter will have to lean over during the descent to avoid falling over backward and stay balanced on the midfoot, and that leaned over position is precisely what we want in the low bar squat. Pretty awesome.

Are you one of those people who is deeply, intensely, spiritually, emotionally, and morally opposed to using the TUBOWs? If so, you're probably the type of person whose squat would benefit most from using them. And if your squat benefits, then you benefit, because you'll get stronger - faster.

Where do I get a TUBOW?
You can go to your nearest lumber supply store and get a 4 x 4 (and they'll often cut it to size for you), but if you'd rather just order a 2 foot section of 4 x 4 online and have it show up at your front door, then just click here.
