Here at Tom's Guide, our fitness team is always up for a challenge, and crunches are one of our favorites. We've put in the hours, trying out various crunches and their variations, to bring you our top picks.
Why Choose Crunches Over Sit-Ups?
Before you decide between sit-ups and crunches for your ab workout, let's talk about why crunches are a fantastic choice. According to Harvard research, building a strong core offers numerous benefits. It improves your posture, reduces the risk of injury, and enhances flexibility and range of motion, which helps with both workouts and daily activities.
Best Crunch Variations and Their Benefits
Crunches come in various flavors, making them accessible to most people for core strengthening. However, if you're uncertain, it's a good idea to consult with a medical professional or a personal trainer before starting a new exercise routine.
Some crunch variations target your oblique muscles by incorporating side movements, while others focus on your rectus abdominal muscles (often called the six-pack muscles) through bending and extending your spine. Depending on the type of crunch, you'll also engage other important muscles like shoulders, arms, lower back, glutes, and hip flexors.
Keep in mind that even though crunches are great, they won't magically give you a perfectly toned midsection. Genetics, body fat percentage, and diet also play roles in achieving your goals. We've got five reasons why you might not be seeing those abs despite all your hard work.
The Top 10 Crunches for a Stronger Core
Now, let's get to the good stuff. We've gathered the best crunch variations, putting them to the test for at least a week before adding them to our list. Here they are:
1. Traditional Crunches
The classic crunch, done lying on your back with knees bent and feet flat on the floor. You can place your arms in front of you or behind your head. These primarily target your six-pack muscles while engaging your back and hip flexors, helping you maintain good posture and protect your lower back.
2. Captain’s Chair Crunches
Captain's Chair crunches work nearly all the muscles in your midsection. They are fantastic for your obliques and six-pack muscles. Surprisingly, they also give your arms a good workout as you hold your body weight by pressing into the armrests. Our writer did 50 of these every day for a week - check out the results!
3. Tabletop Crunches
Target your lower abs with tabletop crunches. By keeping your legs raised, you challenge your lower ab muscles and hip flexors. It's an excellent choice if you've been focusing on upper abs or obliques. One of our writers tried tabletop crunches for a week - read about their experience.
4. Standing Oblique Crunches
This variation focuses on your oblique muscles by using side movements. It requires balance and is gentler on the lower back. Beginners can start with just their body weight, but adding ankle weights can intensify the exercise. Find out what happened when we did 50 standing oblique crunches every day for a week.5. Vertical Leg Crunches
Tired of regular crunches? Try the vertical leg crunch by raising your legs toward the ceiling. This targets more of your midsection muscles while supporting your lower back. It also engages the deeper transverse abdominal muscles, obliques, and lower back. We tried vertical leg crunches every day - see the results.
6. Bird Dog Crunches
Bird dog crunches are a full-body workout that targets the core, erector spinae, glutes, hamstrings, upper back, deltoids, and more. They test stability, coordination, and balance while remaining low-impact. Our writer attempted 100 bird dog crunches every day for a week - it's not for the faint of heart!
7. Butterfly Crunches
Butterfly crunches involve bringing the soles of your feet together and opening your knees to the sides. This takes the emphasis off your hip flexors and works your obliques, abs, and inner thighs. You can adjust the difficulty by placing your hands behind your head or folding them across your chest. Try lifting your feet for an extra core challenge.
8. Bicycle Crunches
Bicycle crunches are a classic for a reason. They effectively target your oblique muscles. These rotational exercises work your waist muscles while supporting your lower back.
9. Reverse Crunches
Switch things up with reverse crunches. Instead of lifting your upper body, you lift your legs toward your head and then back down. This engages your deeper core muscles. Just be sure to maintain control and not rock your hips during the exercise.
10. Side Crunches
Also known as oblique crunches, this movement specifically targets your oblique muscles. By lying on your side and drawing your elbow toward your top hip, you can develop those strong oblique muscles. You can even progress to a side plank for added shoulder strength and core stability. Check out our writer's experience doing 50 oblique crunches a day for a week.
The Big Picture
Remember, crunches aren't just about your abs. They engage a complex network of external and internal core muscles, supporting and enhancing movement in various directions. By training your core as a whole, you'll build a stronger foundation that can help you lift heavier and move more efficiently.
