“Technology Hand” is Destroying Your Upper Body Strength

Your electronics are destroying your ability to do push-ups. They’re also wrecking your downward-facing dog. And if you’re doing burpees (shudder), it’s jacking those up too.

The way you position your hands when using a mouse, trackpad on a laptop, or holding your phone all mimic the same problem position. And it’s this position that is creating an epidemic of people who have lobster claws for hands.

Lobster claws are terrible for your ability to get strong and fit.

The positions you spend the most time in will be the positions your body molds into. Just like rocks molded by the wind perpetually blowing from one direction, your body is molded by the repetitive signals you send.

And when you make the hand position that is ubiquitous for using technology, you’re teaching your body to change the original length-tension relationship of your forearm and hand muscles. This changes how your hand articulates with your forearm bones via the wrist, and that changes everything for how your hand functions.

This is also can change how your shoulder functions, more on that later.

The “technology position” puts your wrist extensors in a slightly shortened position and moves your wrist slightly off it’s original axis with your radius and ulna. While your hand, wrist, and forearm are intended to move in all of these ways, flexing and extending, it’s the holding of one position for an extended period of time that is the issue. Hold the “technology position” for long enough and your body starts to form the bones, soft tissue, and nerves within that tissue into the new, less-excellent position.

Hold any position for enough hours per day and your body learns to maintain that position, because that’s the signal you’ve been sending it. In this case, “make strong the slightly flexed, slightly off-axis position”. Then the time comes to use your full range of motion – flexing and extending as much as the joint was intended to – and you can’t.

You place your palms flat on the floor for your workout, and you can’t. It hurts to do so. You have to turn your hands out to the sides like seal flippers, or you prop yourself up on your thumb and fingers instead of having the palm flat to the ground.

A Body Is Always Listening

Your body is always listening and responding to what it thinks you’re asking it to do. By losing range of motion in your hand and wrist, you also change the range of motion and function in your shoulder.

The shoulder joint is capable of a large amount of movement. That means that it can do lots of things, but it also means that it’s got potential to move sub-optimally for the task at hand.

Here are a few factors that lead to sub-optimal movement at the shoulder joint:

  • sub-optimal hand and wrist function, leading to a loading of the shoulder joint that supports faulty movement patterns
  • over-recruitment of bicep and tricep in relation to the pecs, delts, traps, and lats
  • poor technique, literally not knowing how to do a movement correctly, thus recruiting the wrong muscle fibers for the task at hand to “muscle” through it
  • soft tissue around the shoulder joint that is in poor condition (rigid, tight, non-pliable)
  • imbalanced length-tension relationship of the muscles anterior/posterior to the shoulder
  • overusing one movement pattern for long enough that it causes excessive wear and tear in the shoulder joint

It all boils down to the signals being sent and the body positions being chosen. There is a constant conversation happening between your brain and your body talking to each other. The message you send about how your hand and wrist function impacts the signal that is sent to your shoulder joint about how it should function.

Common Hand Position Mistakes

Let’s look at any exercise where hands are on the floor. When your palm is flat to the floor, with fingers facing forward & fully extended, you have a stable base of support that signals to your shoulder how it should function.

If your palms are not flat to the floor, acting to press the floor away from you, you are more likely to let your shoulder blades “float”. Pressing the palm into the floor tells the muscles stabilizing the scapula to ‘brace’. The scapula, humeral head, and ribcage need to work in an organized fashion when moving, or else soft tissue gets inflamed from either being impinged between the bony processes of the shoulder joint or from overuse.

And if you’re in a position where you’re not moving while hands are flat on the floor – like in a straight-arm plank, for example – you still want to be engaging the shoulder girdle correctly.

Turning your fingers outward during a push-up does allow you to make full palm contact with the floor, but, only because you’ve changed the angle the wrist is at in relation to the hand. With fingers turned out, you don’t have to extend the wrist as much, but that also changes the position your elbow must move in as you do a push-up. And that new elbow position inhibits your ability to bend your arm to bring your chest to the floor.



Propping yourself up on your thumb and fingers, instead of flat-palmed to the floor is going to force your thumb to act like the third leg of an easel, stabilizing your entire upper body on the tiny thumb joint. The stability of your arm isn’t the only issue. Having your body propped up on your thumbs and fingers, instead of on your palms, significantly increases the tension throughout the arm, making it much harder to move through an optimal range of motion for a push-up.

If not strong enough for fingertip push-ups, the default push-up in this hand position will be to sink the torso into the shoulder joint, causing a winging of the shoulder blades, which is a clear indicator that the lats and serratus anterior are not bracing the shoulder joint correctly and can lead to injury.

So what are you to do if you can’t support yourself on your hands yet with high-quality stability and control of your shoulder, elbow, and wrist? The video below includes simple solutions you can start on today to bring better mobility and soft tissue reconditioning to your forearms and wrists. When doing the fingers stretch and clench drill, focus on spreading every single joint as straight as possible, and clench each joint as hard as possible, not just from the fist but from each finger joint as well.

Begin now and bring your push-ups and downward-facing dogs to a new level of glory.
