Want a six-pack but tired of crunches? Planks might be the better solution. Crunches can strain your neck and back, while planks engage more muscles, improving core strength and posture. In this article, we’ll cover five plank exercises that carve your abs better than crunches ever could. Ready to switch up your routine and see real results? Keep reading to find out how.
1. Forearm Plank
Overview
The forearm plank is a foundational core exercise that works multiple muscle groups. This basic plank variation helps improve endurance and stability, making it a core workout staple.
Muscles Worked
Rectus abdominis
Transverse abdominis
Shoulders
Back
Glutes
How to Perform
Start by lying face down with your forearms on the ground.
Position your elbows directly under your shoulders.
Lift your body into a straight line from head to heels, engaging your core throughout.
Hold the position, keeping your body as straight as possible.
Why It’s Better Than Crunches
Crunches isolate the rectus abdominis, but the forearm plank engages your entire core, including stabilizing muscles in your back, shoulders, and glutes. This builds overall core endurance and strength, which helps you maintain better posture and avoid injury.
2. Side Plank
Overview
The side plank is excellent for targeting the obliques and improving lateral stability, areas that crunches often neglect. This exercise also enhances balance and coordination.
Muscles Worked
Obliques
Transverse abdominis
Shoulders
Hip abductors
How to Perform
Begin by lying on your side with your feet and hips stacked.
Prop yourself up on one forearm, keeping your elbow directly under your shoulder.
Lift your hips, creating a straight line from your head to your feet.
Hold the position, ensuring your core remains engaged.
Why It’s Better Than Crunches
Side planks focus on the obliques, which are often underdeveloped. Strengthening these muscles leads to better overall core stability, particularly for lateral movements. Crunches, on the other hand, primarily target the front of the abs, leaving gaps in core strength development.
3. Plank to Push-Up (Plank Up-Downs)
Overview
Plank to push-up, or plank up-downs, combine the benefits of a plank with upper body strength. This dynamic movement increases core engagement and calorie burn.
Muscles Worked
Core
Chest
Triceps
Shoulders
How to Perform
Begin in a forearm plank position.
One arm at a time, press up into a push-up position.
Lower yourself back down into the forearm plank, maintaining a straight body line throughout.
Why It’s Better Than Crunches
This exercise adds movement and upper body engagement, making it more effective than static crunches. The constant transitions between forearm plank and push-up positions challenge your entire core, while improving upper body strength and stability.
4. Plank with Leg Lift
Overview
The plank with leg lift increases instability, forcing your core to work harder to maintain balance. This variation also targets the lower abs and glutes.
Muscles Worked
Core
Glutes
Hamstrings
Shoulders
How to Perform
Start in a standard forearm or high plank position.
Lift one leg off the ground, keeping your body stable.
Hold for a few seconds, then switch legs.
Why It’s Better Than Crunches
Adding a leg lift shifts more of the work to your lower abs and glutes, areas that crunches often miss. This exercise also challenges your stability, leading to greater core activation and strength development.
5. Plank with Shoulder Tap
Overview
Plank with shoulder tap is an anti-rotational exercise, meaning it challenges your core to resist twisting. This variation helps improve core control and prevents injury by targeting deep stabilizing muscles.
Muscles Worked
Core
Obliques
Shoulders
Back
How to Perform
Start in a high plank position with arms straight.
Lift your right hand to tap your left shoulder, while keeping your hips stable.
Switch hands, tapping your right shoulder with your left hand.
Continue alternating while keeping your core engaged.
Why It’s Better Than Crunches
This exercise forces your core to resist rotation, which strengthens the transverse abdominis—a deep core muscle that supports stability. Crunches, by comparison, often involve repetitive spinal flexion, which can strain the lower back and lead to poor posture.
Bonus: Plank Variations for Added Challenge
For those looking to intensify their plank routine, here are some advanced variations:
Weighted Plank
Place a weight on your back to increase resistance and further challenge your core.
Plank to Pike
This dynamic movement engages both your upper body and core, offering a more advanced challenge.
TRX Plank
Using suspension trainers, the TRX plank introduces instability, demanding greater core engagement to stay balanced.
Renegade Rows
Incorporating dumbbells into a plank position, renegade rows target the back and arms while also challenging the core.
Common Mistakes to Avoid
When performing planks, avoiding these common errors will maximize effectiveness and reduce the risk of injury:
Sagging Hips
Letting your hips drop puts strain on your lower back and reduces core engagement. Focus on keeping your body in a straight line from head to heels.
Not Engaging the Core
Failing to engage your core minimizes the benefits of the exercise. Actively pull your belly button toward your spine to engage the right muscles.
Holding Your Breath
Planks are an endurance exercise, and breathing helps activate the muscles. Make sure to breathe steadily throughout the exercise.
Benefits of Planks Over Traditional Ab Workouts
Total Body Engagement
Planks work more muscles than crunches, including the back, shoulders, and legs. This results in better calorie burn and a stronger, more stable core.
Injury Prevention
Crunches often lead to neck and back strain, especially when done incorrectly. Planks distribute the load across more muscles, reducing the risk of injury.
Improved Posture and Stability
Since planks engage your entire core and back muscles, they help improve posture and support spinal health, which crunches can’t provide.
Functional Strength
Unlike crunches, which focus on a single plane of movement, planks help develop functional strength, making them more beneficial for athletic performance and daily activities.
Conclusion
If you’re serious about building a strong, defined six-pack, it’s time to ditch the crunches and incorporate plank variations into your workout routine. By engaging more muscles and improving overall core strength, these exercises not only sculpt your abs but also enhance posture, stability, and injury prevention. Start integrating these five plank variations today for a stronger, more functional core.
