There are some exercises that you just can’t get enough of. Three such examples: wall slides, thoracic rotations, and single-leg hip raise.

Unusual names, yes. But while you may not be familiar with these moves, chances are, you should be doing them every day.

Why? Because they help offset the toll that working on a computer—or even a mobile device—takeas on your body.

Specifically, that toll is poor posture, which frequently leads to neck, shoulder, and back pain. And because sitting and slumping as you type surf, or text can consume hours of your day, the more frequently you perform these moves, the better.

The best part: You can do these no-weight, no-sweat exercises anywhere.

Exercise 1: Wall Slides

Stop what you’re doing right now, and imagine that there’s a string attached from the ceiling to your chest. Now believe that the line is being tightened, pulling your chest closer towards the ceiling.

If you were sitting with good posture, your chest wouldn’t rise much. But if you’re like most people, you just raised up a few inches. (You can also remind yourself to sit as tall as you can.)

This is an excellent way to see how much you slump. And if you do, you should start doing an exercise called the wall slide immediately.

For best results, do 10 to 15 reps of this exercise up to three times a day. (It's easy to do in your office, and a great warmup before you lift weights.)

Yes, it looks simple—and it is. But you’ll love how good it makes your shoulders and upper back feel.

Activity 2: Hip Raises

It’s not just slumping that hurts your posture. Directly sitting can be harmful, too.

For instance, when you constantly sit—as most of us do—the muscles on the fronts of your hips become short and tight.

What’s more, your glutes—or butt muscles—actually forget how to contract. (Think about it: With so much chair time, they're not being used for much of anything except padding for your hipbones.)

Now, the combination of tight muscles on the front of your hips and weak muscles on your backside causes your pelvis to tilt forward. This pushes your lower abdomen outward, making your belly pooch out—even if you don’t have an ounce of fat.

Worse, it also puts more stress on your lumbar spine, which can lead to low-back pain.

But the single-leg hip raise can help. It strengthens your glutes and teaches them how to contract again—which helps allow your pelvis to move back in its natural alignment.

Do 5 to 6 reps for each leg, holding the top position of the exercise for 3 to 5 seconds.

Exercise 3: Thoracic Rotation

Like wall slides, this is another excellent exercise for your upper body posture. Just look around your office: See anyone with a hunch in his upper back? (Make sure to take an honest look in the mirror, too.)

Compare his posture to that of Superman. The difference should jump at you: Superman has his chest up, and shoulders pulled back; your colleague is just the opposite.

The reason is simple: Your muscles and connective tissue tend to “set” in the position your body is in the most often.

Now you can’t fix 8 hours of slumping with just one exercise. But you can counteract some of the daily damage using thoracic rotation.

This exercise helps “mobilise” your upper back by rotating at your thoracic spine. (That’s where the name comes from.)

Do 10 reps on each side. Frequently.
This helps restore natural, healthy posture. It also feels perfect!
