Weekend Challenge: The Single-Arm Overhead Press

This weekend we’re going to look at a unique way of exercising for your bones. It’s called unilateral training, which means that it works one side of your body at a time. Ironically, it helps restore balance to both sides of your body.

You see, we’re all asymmetrical – one side of our body is stronger than the other. For lefties, that usually means the left side; it’s the opposite for righties. So exercises that work both sides of the body at the same time, allow for a little β€œcheating”. In other words, we all tend to compensate for our weak side by overusing the stronger side (I know I do!).

The Single-Arm Overhead Press is one example of upper body unilateral training. When you practice this exercise, you’re lifting less total weight than if you lifted two weights (or a larger weight with both arms), thus sparing your back and joints and reducing injury risk. But more importantly, this exercise builds the muscles and bones of your arms and your upper body. This is critical to prevent fractures in case you fall, especially wrist fractures. It also improves your posture by targeting your core and shoulder muscles.

Not to mention that it’s always more attractive to look symmetrical, especially since after you practice this exercise for a while, both of your shoulders will be level (we tend to position the stronger shoulder lower than the weaker side).

Why: Besides preventing the dreaded wrist and other upper body fractures, the Single-Arm Overhead Press has unique benefits mainly because it’s a unilateral exercise.

When you work one side of the body at a time, your core muscles naturally contract to hold you upright. This β€œawakens” those important behind-the-scenes muscles that hold you straight and help you stay balanced.

The Single-Arm Overhead Press, like other unilateral exercises, stimulates your brain and muscles to work together. That’s why unilateral exercises can feel challenging at the beginning – your nervous system has to adapt to the off-center movement. But as you continue the exercise, your brain and muscles will coordinate, and you will actually form new synapses in your brain. Then you benefit from more efficient motion. In a very real way, this exercise makes you smarter!

Unilateral exercise helps prevent injury as well, especially the type that occurs from muscular compensation. When a muscle or muscle group is weak, it can’t do its job of stabilizing the joints and bones. The resulting joint rotation is abnormal, and your body compensates with other muscles that are less suited to the job. This creates a site of weakness, where injury – including fractures – is more likely to occur.

When you practice the Single-Arm Overhead Press, you’ll build your bones by working both sides of your body separately. Your body becomes more balanced, less injury-prone, and better able to build bone density through exercise.

How: This is a standing exercise, so stand near a chair in case you need to grab it to steady yourself.
You’ll need a small dumbbell that’s a comfortable weight for you to lift with one arm, but still a bit challenging (2 to 5lbs is a good place to start). Or you can use a can of food.

We’ll start with the left hand.

  1. Take the dumbbell in your left hand.
  2. Bring your left hand up with the palm facing in.
  3. Your elbow should be bent and pointing straight down.
  4. Slowly raise the weight up over your head, straightening your arm.
  5. Bring your arm back down to its starting position.
  6. Repeat 3 sets of 10 repetitions on each side. If you notice that one arm is much weaker than the other, you can do more repetitions with the weaker arm. After a while, arm strength in both arms should be about the same.

Tips:

  • Don’t arch your back or lean backward.
  • As mentioned earlier, feel free to do a few extra reps on your weak side for better body symmetry.
  • Keep your palm facing in so your elbow doesn’t stick out to the side.
  • Don’t let your elbow point inward as you lift.

For a more advanced variation of the Single-Arm Overhead Pass, you can try the following variation:

Single-Arm Overhead Pass (Progress To Walking)

For this variation, you simply perform the above exercise while walking. Do the same number of sets and reps, and switch sides as you walk.

I love to share these Weekend Challenges with you because good nutrition and regular exercise come into play for building strong, healthy bones. There’s tons of helpful bone health information at this website, but if you really want to bring your bone health to the next level, the Osteoporosis Reversal Program and Densercise can show you step-by-step how easy it is to incorporate both into your daily life.
