What is an upright row?
The upright row is a free-weight exercise that targets the lateral deltoids, upper traps, rhomboids, and biceps. Usually, it is performed using a standard barbell or EZ curl bar.
What are the best alternatives to the upright row?
The greatest alternatives for the upright row involves a similar movement pattern as the upright row, while targeting the lateral deltoids, upper traps, rhomboids, and biceps. The best exercise for you depends primarily on the equipment you have available and how specific you need your upright row substitute to be.
How do you prove a row replacement operation?
If by row replacement operation you mean "adding one row to another or something of that sort", then the last theorem stated proves it.
What is row replacement in matrix?
A row can be replaced by the sum of that row and a multiple of another row. If E is an elementary matrix, as described below, to apply the elementary row operation to a matrix A, one multiplies A by the elementary matrix on the left, EA.
What is a row Exchange?
(Row Swap) Exchange any two rows. • (Scalar Multiplication) Multiply any row by a constant. • (Row Sum) Add a multiple of one row to another row.
Does row replacement affect determinant?
Hence, replacing a row by a linear combination of rows does change the determinant if the coefficient that multiplies the row being replaced is not 1. For example, replacing a row by the same row multiplied by 2 then doubles the determinant.
What are the 3 row operations?
There are three types of matrix row operations: interchanging 2 rows, multiplying a row, and adding/subtracting a row with another. Each notation for this is different, and is displayed in the note section.
What is row operation?
Row operations are calculations we can do using the rows of a matrix in order to solve a system of equations, or later, simply row reduce the matrix for other purposes. There are three row operations that we can perform, each of which will yield a row equivalent matrix.
What is back substitution?
Mathwords: Back-Substitution. The process of solving a linear system of equations that has been transformed into row-echelon form or reduced row-echelon form. The last equation is solved first, then the next-to-last, etc.
When two rows of matrix A are interchanged then?
(c) If any two rows or columns of a determinant are interchanged, then the value of the determinant changes in sign.
What is det 3A?
3A is the matrix obtained by multiplying each entry of A by 3. Thus, if A has row vectors a1, a2, and a3, 3A has row vectors 3a1, 3a2, and 3a3. Since multiplying a single row of a matrix A by a scalar r has the effect of multiplying the determinant of A by r, we obtain: det(3A)=3 · 3 · 3 det(A) = 27 · 2 = 54.
What is the relationship between Det A and det Ka?
If A is an n × n matrix, and k is any constant, then detkA = kn detA. When using the theorem, it is important to keep in mind that the constant k in the determinant formula gets multiplied by itself n times, since each of the n rows of A was multiplied by k.
What is column and rows?
Rows are a group of cells arranged horizontally to provide uniformity. Columns are a group of cells aligned vertically, and they run from top to bottom. Although the main reason for both rows and columns is to bifurcate groups, categories and so on, there is a fine line of difference between the two.
What is row multiplication?
Row multiplication is a very simple row operation. You can take any row and multiply all its elements by any constant. Algebra 2Matrix Row Operations.
What is row reduction?
Row reduction (or Gaussian elimination) is the process of using row operations to reduce a matrix to row reduced echelon form. This procedure is used to solve systems of linear equations, invert matrices, compute determinants, and do many other things.
What is an upright row?
The upright row is a free-weight exercise that targets the lateral deltoids, upper traps, rhomboids, and biceps. Usually, it is performed using a standard barbell or EZ curl bar. However, you might be looking to substitute the upright row for a few reasons: perhaps this exercise is painful to perform because you’re injured, ...
What is the best exercise to replace the upright row?
1. Barbell High Pull. The barbell high pull is a fantastic substitute for the upright row, as it very closely resembles the upright row and uses all the same muscle groups. If specificity to the upright row is important to you, then look no further than the barbell high pull.
What is the difference between barbell high pull and upright row?
In the upright row, there is minimal help from the legs to drive the barbell upwards — preferably, none at all. On the other hand, the barbell high pull is performed by deliberately incorporating hip drive from the legs.
What muscles are used in the upright row?
The muscles used in the upright row are the: • Lateral delts. • Upper traps. • Rhomboids. • Biceps. The upright row requires a significant amount of humeral abduction (bringing the upper arm directly out to the side) and scapular elevation (lifting the shoulder blades upwards).
What is the position of the arms while doing the upright row?
While performing the upright row, the lifter’s arms travel away from their body and their shoulder blades lift upward near the top of the movement. The elbows also bend slightly throughout the exercise.
Is the upright row a machine based exercise?
As a machine-based exercise, you’ll lose some specificity to the upright row by selecting this exercise as a substitute since you’re not using a barbell. However, it’s still a great exercise to target the deltoids, rhomboids, and biceps.
What is a single arm row?
The single arm row can be done with a dumbbell, kettlebell, or other type of equipment (see below). This is a great way to increase muscle activation via increasing the rowing range of motion. Additionally, this barbell row alternative can be used to address any muscle imbalances or movement asymmetries a lifter may possess that would otherwise go unseen when using a barbell.
What is inverted row?
Inverted Row. The inverted row can be done with a barbell, bar, or TRX band. While loading may be less than a standard barbell row, the lifter can still train many of the same muscle groups involved in the row movement and still developer back strength, muscle mass, and even increase body awareness and core stability. YouTube.
What is gorilla row?
The gorilla row is a barbell row variation that has a lifter perform a Pendlay row with either dumbbells or kettlebells, doing them in an alternating fashion. This can be done to increase back, hip, and even core strength. Instagram. mikejdewar. New York, New York.
What is a pendlay row?
The Pendlay row is a rowing movement specific to the deadlift and clean. It slightly differs from a standard barbell/bent over row in that the lifter places the load on the floor. This can work to increase hamstring stability and concentric strength in the row, both vital for deadlifting and pulling strength and integrity.
What is a T bar row?
While the lifter may not have to support their own body like other variations, the T-bar row is a barbell row alternative that takes all other aspects of the bent over row position out of the equation, solely focusing on back strength.
What is bent over row?
Bent Over Row. The bent over row is often the exercise performed when most people refer to a barbell row (however not always the case, see below exercise). This can be done with a barbell, dumbbells, or even kettlebells.
When was the last time the barbell row was updated?
Written by Mike Dewar. Last updated on January 7th, 2019. In this article we will discuss the barbell row and its alternatives for growing a stronger, more muscular back.
What is barbell row?
The barbell row allows you to load heavy weights onto the lats. Getting into the bent over position and keeping your back (virtually) parallel to the floor while pulling heavy weights is a great way to build a solid foundation of muscle and strength. Mixing up these other exercises into your routine to get a break from the barbell row is also ...
What is standing band row?
Standing Band Row. The standing band row is one of three excellent band row variations to perform instead of a barbell row. I love this one because you get similar muscle activation in your lats, but you don’t have to bend over like in a standard barbell row. This makes the movement technically easier to perform.
What is the best exercise to do with dumbbell rows?

What grip do you use for barbell row?
Note: the variation of the barbell row they show is with an underhand grip. While mixing in an underhand grip occasionally might be a good idea, personally I use an overhand grip almost 100% of the time because it allows me to focus more on the upper back and lats, and limit biceps involvement.
What muscles do barbell row work?
The barbell row primarily targets the latissimus dorsi (aka ‘lats’). Other secondary muscles include: Rear deltoids and trapezius. Biceps brachii and forearms. Rhomboids. Spinal erectors. All of the following exercises target primarily the lats, as well as most of the secondary muscles listed here.
What is a half kneeling high band row?
One of the more unique exercise alternatives to the barbell row, the half kneeling high band row is a great unilateral movement. With this exercise, you can target your lats precisely and use a different angle than usual for rows. Make sure to pull the band down to your lower abs and squeeze your scapula. 8.
