Wall Angels: How to Do Them Correctly for Better Posture
Key Takeaways
- Wall angels strengthen the muscles between your shoulder blades (rhomboids and lower trapezius) while stretching your chest. This targets the exact imbalance behind rounded shoulders.
- The most common mistake is arching your lower back off the wall. If your back lifts, you are compensating with the wrong muscles.
- Start with 2 sets of 8 reps. If you cannot keep your wrists on the wall through the full range, reduce the range of motion rather than forcing it.
Wall angels are a posture exercise where you stand with your back flat against a wall and slide your arms up and down in an arc, keeping your wrists and elbows in contact with the wall the whole time. They strengthen the muscles that pull your shoulder blades together and stretch the tight chest muscles that pull your shoulders forward. If you have rounded shoulders from desk work, this is one of the first exercises worth adding to your routine.
How to Do Wall Angels
Stand with your back against a wall. Your feet should be about 6 inches from the baseboard. Press your entire back against the wall: lower back, upper back, and the back of your head. If your head does not reach the wall, tuck your chin slightly until it does. This starting position alone is a stretch for most desk workers.
Raise your arms to form a goalpost shape: elbows at shoulder height, bent at 90 degrees, forearms pointing up. Press your elbows, forearms, and the backs of your wrists against the wall. This is harder than it sounds. If your chest and front shoulders are tight (and if you sit at a desk, they probably are), getting everything flat against the wall takes real effort.
From the goalpost position, slowly slide your arms up along the wall until they are nearly straight overhead. Keep your elbows and wrists in contact with the wall the entire time. Then slide them back down to the goalpost position. That is one rep. The movement should be slow and controlled. Two to three seconds up, two to three seconds down. If you rush it, you lose the benefit.

Common Mistakes
The biggest mistake is arching your lower back off the wall as your arms go up. This happens when your shoulders are too tight to complete the full range of motion, so your body compensates by extending through the lower back instead. Fix it by only sliding your arms as high as you can while keeping your lower back pressed firmly against the wall. Your range will improve over time.
Second mistake: letting your wrists peel off the wall. If your wrists cannot stay on the wall through the full range, go as far as they can stay in contact and work that range. Forcing your arms up with wrists off the wall trains the wrong movement pattern.
Third: going too fast. Wall angels are not a cardio exercise. The benefit comes from slow, controlled movement against gravity. The eccentric phase (sliding down) matters as much as the concentric phase (sliding up). I spent weeks doing them fast and wondering why they did not seem to help. Slowing down changed everything.
If rounded shoulders are your main issue, wall angels are one piece of the puzzle. Pair them with chest stretches and resistance band exercises for a more complete approach.
Progressions
Once you can do 3 sets of 10 with full range of motion (wrists on the wall, arms fully extended overhead, lower back flat), the basic version will start to feel easy. Here is how to progress.
Add a hold. At the top of each rep, pause for 3 to 5 seconds with your arms as high as they go while maintaining wall contact. The isometric hold at the top builds endurance in the lower trapezius and serratus anterior, which are the muscles most responsible for keeping your shoulder blades in position during the day.
Move to the floor. Lie on your back with knees bent and perform the same arm movement. The floor removes the assistance of gravity that the wall provides, making the exercise harder because your arms have to push into the floor throughout the range.
Add resistance. Hold a light resistance band between your hands during the movement. Even a thin band adds enough tension to make the strengthening component more demanding. Start with the lightest band you can find. This exercise is about control, not load.
