A wider grip will result in more focus on the back muscles, while a narrower grip will result in more focus on the biceps.
A more upright lean will target the upper back muscles more, while a more bent-over lean will target the middle back muscles more.
At first glance, it’s easy to dismiss the notion that there is any complexity to rowing movements. However, because most rowing movements involve stabilizing the spine, suddenly we have a whole new set of variables to find, including spinal loading, the degree of spinal movement and the spine stiffness. The rowing movement is an antero-posterior one, which means that the direction of force runs perpendicular to the body. However, this isn’t the whole picture, because muscular activity of the spinal muscles actually creates compressive forces, so although the rowing movement is antero-posterior, significant axial compressive forces will also be produced down the spine. Since the spine is subjected to significant shear forces during rowing movements, unless the muscles around the spine create forces to prevent its movement, these shear forces will cause flexion of the spine. The researchers wanted to investigate three different rowing exercises: the bent-over barbell row, the inverted row and the one-arm cable row. While the subjects performed each lift, the researchers monitored the electromyographical (EMG) activity of various leg, back and abdominal muscles, including the right and left rectus abdominis, right and left external oblique, right and left internal obliques, right and left latissimus dorsi, right and left upper (thoracic) erector spinae, right and left lumbar erector spinae, right gluteus medius, right gluteus maximus and right biceps femoris. The researchers recorded the muscle activity of the various muscles and reported them as a percentage of MVC.
The chart shows that the various rowing movements produced very different levels of leg muscular activity.
The chart shows that the one-armed cable row has a very different pattern from the other exercises in terms of back muscle activity.
The researchers noted that the one-arm cable row demonstrated significantly higher activity of the right internal oblique and the left external oblique, as might be expected during the one-arm movement using the right arm.
The researchers found that spinal movements were very different between the three rowing variations. The researchers found that the standing bent-over row displayed very significantly higher compressive forces as a result of the muscles contracting around the spine. The chart shows that the flexor stiffness was greatest in the bent-over row and lowest in the one-arm cable row. The bent-over row produced the lowest levels of latissimus activity, high levels of upper erector spinae activity and the highest levels of lumbar spine activity, suggesting that the lower back muscles were being worked significantly during this exercise. Summary: overall, the bent over row is an evenly-distributed upper-and-lower back exercise but produces high compressive forces, which tests the ability of the spine to stabilize itself.
The inverted row produced the highest levels of latissimus and upper erector spinae activity but lower levels of lower erector spinae activity.


The researchers noted that the inverted row produced much higher upper back activation than lower back activation, which they noted would be ideal for an early rehabilitation program in which lumbar loading was contraindicated. The researchers concluded that inverted rows produce the least overall movement of the spine. Summary: the inverted row is the most effective of the three exercises for targeting the lats and the upper back while simultaneously sparing the spine, avoiding stress on the lower back and avoiding recruitment of the hip flexors. The one-arm cable row also produced high levels of latissimus and upper erector spinae activity but the lowest levels of lower erector spinae activity. The researchers concluded that one-arm cable rows produced the greatest amount of rotational motion of the spine, which is nearly 70% of its maximum available motion.
Summary: the one arm cable row is another upper-back and latissimus-focused exercise that activates the obliques significantly.
One of the key limitations to this study was that some key mid-back muscles weren’t tested, such as the mid-traps and rhomboids. Another obvious limitation was that the chest-supported row wasn’t covered, as this exercise has a support for the torso, which may have reduced the spinal movements and forces significantly, making it an even better choice for rehabilitation than the inverted row.
To make sure you can train well into old age, build your upper back and latissimus routine around weighted inverted rows rather than bent-over rows or one-arm cable rows and avoid both spinal forces and rotational movements. Now, the starting position would ideally have your body fully extended, and your rib cage over your pelvis, but unfortunately since many gyms have pull-up bars that are too low, a lot of times, you won’t be able to start in the fully extended position. I spent months doing dumbbell rows and inverted rows, but when I tried to test myself on the pull-up bar, I failed miserably. By doing other exercises like inverted rows and dumbbell rows sure, you’ll get stronger, but you’ll get stronger only at those lifts.
This means that when the time comes to lift heavy weights, more voltage will be able to flow through your muscles, which will result in harder contractions.
In order to get how much work you’ve done in a day for example, simply multiply the number of reps with your bodyweight, in order to get your total daily tonnage.
A lot of fitness pros would suggest that you should work each muscle group two times per week tops, in order to let them fully recover.

Additionally, as we will see with single-arm movements, there is also scope for rows to cause rotational movements. In doing so, they set out to establish the muscular activity levels of the back, leg and abdominal muscles, the spinal loading, the degree of spinal movement and the spine stiffness. The one-armed cable row (with the right arm) produced much less back muscle activity in the right and left lower erector spinae and very little (obviously) in the left upper erector spinae and left latissimus dorsi.


Other than these differences, the abdominal activity during the various rowing movements appears surprisingly similar. They suggested that inverted rows might therefore be the best option for those with an overall intolerance to spinal movement. This suggests that for individuals who are rotational motion-intolerant, the cable row might be a poor choice. However, the bent-over row produces greater overall back muscle activity, including the lower back, and challenges spinal stability the most.
There’s almost no other upper body exercise that’s so simple to do, while being so effective. As long as you have a bar that’s able to withstand your bodyweight, then it’s your job to do as many pull-ups as you possibly can. Synaptic facilitation is just a fancy word for saying that your motor neurons—the neurons that fire your muscles—will reinforce its connection to your muscles and it may also form brand new synaptic connections.
By training every day with heavy weights, for years on end, their neurons are able to discharge a shit-load of juice into their muscles.
But next time I have your article to refer to so I can build my muscles stronger and faster. No Brainer Muscle exists for a simple reason – to serve as a resource of practical and easy to use information, for people that are struggling to reach their fitness goals. Of course, there are the normal questions that you get with any multi-joint exercise, such as what is the muscle activity during different variations and the relative muscular effort of the various muscles with increasing load. Since shear forces are more damaging to the spine than the compressive forces that occur with axial loading, it is useful to know the shear forces during rowing movements.
This stiffness of the spine under load is governed by the activity levels of the muscles that surround it. However, this is because of the one-arm nature of the row. Perhaps more interesting is that the latissimus activity is clearly higher in the right arm of the one-arm cable row and in the inverted row than in the bent-over barbell row. The researchers suggested that the large antero-posterior forces produced a large moment on the lumbar spine, which the lower back muscles had to resist, thereby producing very large compressive forces and stiffness to stabilize the lumbar spine.
The researchers noted that this movement was very small in absolute terms but very large in relative terms, so it could easily be missed, making the one-arm cable row an exercise that should be carefully monitored for form. Muscle-ups are an exercise, where you start at the bottom position like with the pull-ups and then you pull yourself up and over the bar.
