This Coach Was Sore for 6 Days After Dragon Flags, But Still Doesn’t Recommend Them. Here’s the Exercise He Does Instead

Dragon flags have earned their reputation as one of the most impressive core exercises out there.

Made famous by Bruce Lee and later showcased by Sylvester Stallone in Rocky 4, this movement looks incredibly challenging and effective.

But according to calisthenics expert Sven from Kelly Move, dragon flags might not be the best choice for targeting your abs, even if you’re an advanced athlete.

In a recent analysis, he breaks down exactly why simpler exercises often deliver better results with less risk and hassle.

What Makes Dragon Flags So Challenging

Dragon flags definitely hit your core hard. Your lower abs work intensely to lift your legs, while your entire six-pack contracts isometrically to keep your spine extended.

Sven recalls his first experience with the exercise, noting that his upper abs remained sore for five or six days afterward. That level of soreness indicates serious muscle engagement.

However, the dragon flag isn’t purely an ab exercise, and that’s where things get complicated.

The Hidden Demands Beyond Your Core

While dragon flags appear to be a straightforward core movement, they actually function as a compound exercise that recruits multiple muscle groups simultaneously.

To lift and control your body during a dragon flag, you must grip an object behind you, which transforms the movement into something resembling a reverse pullover. This means your lats, chest, and serratus anterior actively contribute to raising and lowering your body.

Your triceps also face significant demands. Because your elbows remain flexed while gripping the bench, your triceps stay under continuous isometric load comparable to the bottom position of a skull crusher.

Even though the dragon flag creates a static hold for your abs, your body moves around the shoulder joint, requiring substantial upper body strength and shoulder stability.

Comparing Dragon Flags to Hanging Leg Raises

Sven initially gravitated toward dragon flags because he found hanging leg raises problematic. Without anything to stabilize your torso during hanging variations, it becomes tricky to avoid swinging back and forth.

That instability limits tension directed into your abs. While a Roman chair fixes most of this issue, your back, arms, and shoulders still must support your body weight.

Wait a second. That’s exactly what a dragon flag does not fix.

Dragon flags actually demand even more work from supporting muscles than leg raises. You already need an advanced level of strength in your arms, upper back, and shoulders just to perform the movement properly.

Why Swinging Doesn’t Ruin Your Ab Training

Body shifts during hanging leg raises happen mainly for two reasons. First, performing the movement too quickly makes stabilization harder.

Second, tight lats and chest muscles limit proper shoulder positioning and control. When these muscles lack flexibility, lifting your legs while keeping your torso perfectly in place becomes difficult.

Here’s the important part: this doesn’t negatively affect your ab training. Even if your body tilts slightly backward or you swing a little, you’ll still train your abs effectively.

The only real issue occurs when you rely too much on momentum, using your legs to swing up instead of lifting them with control and strength.

The Setup Problem With Dragon Flags

Beyond the muscle recruitment issues, Sven identifies practical problems with dragon flags that make them less appealing for regular training.

To perform a proper dragon flag, you basically need a padded bench. Without one, you place excessive pressure on your cervical spine, and your neck ends up in an uncomfortable position.

Even with proper equipment, the position still feels awkward for many athletes.

Another concern involves elbow stress. When you grip the bench at a very acute angle, it places high stress on your elbows. Sven experiences this clearly, as do many clients and athletes he’s worked with.

Better Alternatives: The Roll Out

For similar benefits with fewer drawbacks, Sven recommends roll outs using an ab wheel, rings, or suspension trainer.

The big advantage? You’re not lying on or putting pressure on your neck. You still need good shoulder stability because your extended arms require solid lat and chest strength to keep the shoulder joint stable.

Roll outs also offer excellent progression options:

• Start on your knees or limit range of motion
• Gradually work toward full roll outs as strength increases
• Use plank walks or long lever planks if equipment isn’t available

Roll outs function as advanced compound movements with strong abdominal focus, similar to dragon flags but with better cost-benefit ratio.

Three Superior Bodyweight Ab Exercises

For movements that target your abs more directly without relying heavily on other muscle groups or mobility, Sven recommends three alternatives.

Lying Leg Raises

This variation functions as an easier version of dragon flags. Your back stays pressed against the floor or bench, eliminating the need for lat, chest, or tricep strength to lift your body.

Keep your lower back neutral or slightly rounded, and raise your shoulder blades off the floor similar to a crunch to maximize abdominal engagement.

Candle Raises

This movement almost completely removes hip flexor involvement. Your legs stay in a straight line above your body, which minimizes leverage but still provides strong ab activation through pelvic tilt.

Though it appears small, that subtle upward tilt proves incredibly effective for core development. You can also lift your shoulder blades off the ground simultaneously to engage upper abs more.

Hollow Body Crunch

Lift both legs and shoulder blades off the ground at once, bringing the origin and insertion of your abs closer together for maximum contraction.

Keep your lower spine neutral and maintain a posterior pelvic tilt. If this proves too challenging, shorten the lever by bringing arms and legs closer to your body.

The Training Volume Consideration

Dragon flags demand significant work from muscles beyond your core, particularly your lats, triceps, and shoulders. This makes the exercise more of a compound skill than a pure ab builder.

Adding dragon flags to your routine increases training volume for triceps, chest, and lats. If you’re already performing substantial work for these muscle groups, remember that dragon flags also hit them considerably.

Account for this extra overlap in your weekly training volume to avoid unnecessary fatigue or recovery issues.

Making Your Choice

Dragon flags definitely rank among the most impressive and effective full body core movements available. They build serious strength and control.

However, they also demand considerable contribution from muscles that aren’t your abs, especially lats, triceps, and shoulders.

If your goal centers on targeting abs more directly without heavily involving upper body musculature, simpler exercises like lying leg raises, candle raises, or hollow body crunches usually prove the smarter choice.

These movements are easier to control, place tension exactly where you want it, and let you focus on quality ab contraction instead of just surviving the movement.

For most athletes seeking efficient ab development, less impressive but more targeted exercises deliver better results with lower injury risk and easier setup requirements.
