7 Hardest Ab Exercises To Challenge

Dragon Flag

The Dragon Flag is an exercise known for engaging the entire core and building incredible abdominal strength. It requires a high level of control and stability, making it one of the hardest ab exercises.

Instructions:

• Lie on your back on a flat bench or mat with your upper body extended and your hands gripping the bench behind your head.
• Lift your legs and hips off the bench, keeping your upper body fixed and straight but your knees bent.
• Slowly lower your legs and hips toward the bench, maintaining control throughout the movement.
• Once your legs are parallel to the bench, reverse the movement and lift your legs and hips back to the starting position.
• Aim for eight to ten reps per set.

Standing Barbell Rollout

The Standing Barbell Rollout is a challenging exercise that targets the entire core, including the rectus abdominis, obliques, and lower back muscles. This exercise requires a barbell with weight plates.

Instructions:

• Stand upright with your feet shoulder-width apart, knees slightly bent, holding a barbell with an overhand grip. Your hands should be slightly wider than shoulder-width apart, and the barbell will be resting on your upper thighs.
• Bring the barbell to the floor and slowly roll it forward, keeping your core engaged and your back straight.
• Continue rolling until your body is fully extended, with your arms overhead and your torso parallel to the floor.
• Reverse the movement by pulling the barbell back towards your body, returning to the starting position.
• Aim for eight to ten reps per set.

TRX Oblique Crunch

The TRX Oblique Crunch is an intense exercise that targets the obliques, the muscles on the sides of your abdomen. It requires a TRX suspension trainer or any other suitable suspension training system. 

Instructions:

• Place your feet in the handles of the TRX suspension trainer and get into a plank position with your arms straight.
• Inhale and brace your core as you bring your knees up toward your chest and to one side.
• Hold here momentarily before exhaling and slowly straightening your legs back out.
• Repeat on the other side. Aim for ten to 12 reps on each side.

Hanging Dragonflies

The Hanging Dragonflies are an advanced hanging leg exercise that targets the entire abdominal area, including the upper and lower abs. This exercise requires a pull-up bar or any sturdy overhead bar. To adapt this exercise for beginners, you can start from a position of rest, such as on a stability ball.

Instructions:

• Hang from the bar with your arms fully extended and your legs together.
• Engage your core and raise your legs up in front of you, keeping them straight.
• Once your legs are parallel to the floor, use your abs to lift your hips and curl your body into a tuck position.
• Slowly reverse the movement, extending your body back to the starting position.
• Aim for eight to ten reps per set.

Oblique V-Ups

Oblique V-Ups are a challenging exercise that specifically targets the oblique muscles, helping to carve out a defined waistline. They’re great for weight loss as well as for building strength.

Instructions:

• Lie on your right side with your legs straight and stacked on top of each other – left leg on top of the right leg. Rest your right arm on the floor for support, and place your left arm above you, with the hand behind your head.
• Keeping your legs pressed against each other, lift your legs up off the floor and bring your left elbow toward your left knee while contracting your obliques.
• Slowly lower your legs and torso back to the starting position.
• Repeat the movement on the other side.

Weighted Plank

There are many plank variations, but the Weighted Plank is one of the most intense. This exercise adds resistance, creating a demanding exercise for the entire core.

• Hold the position for a specified time, such as 30 to 60 seconds. 
• Remember to breathe and maintain proper form throughout the exercise.

Human Flag

The Human Flag is an incredibly challenging exercise that targets the core and requires significant upper-body strength and stability. It involves holding your body horizontally while gripping a vertical pole or bar.

Instructions:

• Stand next to a sturdy vertical pole or pull-up bar and grip it with one hand above your head and the other hand lower down.
• Engage your core and lift your feet off the ground, extending your body horizontally.
• Keep your body tight and straight, with your lower arm pushing down on the pole for stability.
• Hold the position for as long as you can maintain proper form and control.
• Aim for shorter durations initially and gradually increase over time.

Common Mistakes When Doing Exercises

Sacrificing Form For Quantity

When doing ab exercises, focus on quality over quantity. It can be tempting to rush through the movements, but rushing can increase the risk of injury. 

To maximize the benefits of upper ab workouts and others, maintain proper technique throughout each movement. Slow down, engage the targeted muscles fully, and ensure controlled and deliberate execution. 

Neglecting Warm-Ups

Don’t skip warm-ups before ab workouts. A proper warm-up routine^[1] helps prepare your core and activate the targeted muscles, increasing blood flow and flexibility. 

Prioritize dynamic stretches and light cardiovascular activity to warm up your body and loosen up your muscles. A few stretches can maximize performance and prevent injuries during lower ab workouts, general ab workouts, or any workout.

Ignoring Warning Signs

Feeling uncomfortable when you’re pushing yourself is normal, but serious pain could be a sign that something is wrong. Listen to your body. If you feel severe pain, sudden discomfort, or joint instability, stop immediately – pushing through pain can aggravate existing injuries or lead to new ones.

Pay attention to exhaustion, too. Start thinking about your nutrition if you feel like you can’t make it through a workout, especially repeatedly.

You might even consider supplements for extra protein and nutrients and to aid weight loss. It’s also possible your workout is just too intense, and you might need to tone it down a bit.

Safety Tips

When performing the hardest ab exercises, safety should be a top priority. Here are some safety tips to remember:

1. Start with proper warm-up exercises to prepare your core and activate the targeted muscles.
2. Focus on maintaining proper form and technique throughout each exercise to prevent injuries.
3. Gradually increase the intensity and difficulty of the exercises as your core strength improves.
4. If you have any pre-existing medical conditions or injuries, consult with a healthcare professional before attempting these exercises.
5. If you experience any sharp or prolonged pain during the exercises, stop immediately and seek medical advice.

The Bottom Line

These difficult ab exercises build a strong core, improve stability, and define abs by targeting multiple muscle groups. A beginner may want simpler core stabilization exercises,^[2] but these are some of the most intense you can get.

Remember to exercise with proper form and technique to minimize injury; listen to your body and progress only gradually. Combine these exercises with a well-rounded fitness program, proper nutrients, and adequate sleep, and you’ll be unstoppable.
