Let’s settle the whole sit-ups vs. crunches argument once and for all!

A sit-up is typically an abdominal exercise chiefly responsible for strengthening one’s core. Be it sit-ups or crunches, both are multi-muscle exercises, meaning that they work multiple muscles at one go. However, sit-ups are an exercise that works specifically on the chest muscles, lower back muscles, hip flexors, rectus abdominis (abs), transverse abdominis, neck muscles, and obliques. Because of the holistic range of motion, sit-ups can do all this simultaneously. But, there is much more to sit-ups and why people choose them. Let us explore the advantages and disadvantages of sit-ups.
The Advantages of Sit-Ups Are
- Inexpensive– Many workouts these days require expensive gym equipment. Not that they are unaffordable, but they also add up to rising consumerism. Sit-ups or crunches are the types of workouts that anyone can add to their beginner workout routine without worrying about the purse and taking a gym membership. All this workout demands is a yoga mat and motivation.
- Enhances Stability– So now that it is clear that sit-ups strengthen the core by working on muscles such as rectus abdominis they are also responsible for better stability. It becomes easy to perform daily activities with improved core stability, such as climbing stairs, bending, etc. In addition to that, one can shove off the chances of experiencing pain in old age with a strong core. Weak legs and lower back problems are common old age problems one can avoid with a strong core. Sit-ups or crunches can both help here.
- Strengthens Hip Flexors– Sit-ups or crunches are compound exercises and work on multiple muscles simultaneously. Hips come under the muscles that sit-ups specifically work on strengthening. Hip flexors play a key role in basic daily movements such as jumping, bending, walking, twisting, etc. Therefore, these movements do not become troublesome if you do sit-ups daily.
- Improves Posture– Not like a stunning model, but everyone wishes for a well-defined, decent posture. A good posture is a sign of having a good core. Keeping the sit-ups or crunches argument aside, we can stay assured that regular sit-ups can improve the posture. We all wish to gain an appropriate posture, and one way of attaining this is by doing sit-ups. One of the significant benefits of performing regular sit-ups is that you get a poised posture.
Disadvantages of Sit-Ups
Be it sit-ups or crunches, or any exercise; every workout has its downsides. However, the most significant disadvantage of sit-ups is the risk of injuries. Neck and lower back injuries are the most complained about problems with sit-ups. This happens mostly because of the wrong form. This being clear, let us jump straight into the form and steps to do to perform sit-ups.
Steps To Perform Sit-Ups
- Lie down straight on your back.
- Then, bend your legs and place your feet firmly on the ground and make your lower body stable.
- Now, keep your hands behind your neck with elbows pointing away from you. Again, do not pull or strain your neck.
- In this position, curl your upper body towards your thighs and knees. Breathe out once you complete the lift.
- Then, gradually lower yourself down, and after a few reps, return your starting point. Don’t forget to breathe out while lowering yourself.
If you are a beginner, aim for at least 10 reps in one go. You can have a leg workout as a brownie point if you get the leg form right during sit-ups!
For settling our sit-ups or crunches debate, let us turn now to crunches. Crunches are an abdominal exercise that is a near replica of sit-ups. However, the key difference between the sit-ups or crunches lies in the range of motion of the two exercises. Crunches, particularly, have a small range of motion compared to sit-ups. While a crunch, you only lift your shoulders off the ground while your lower back remains on the floor. Sit-ups or crunches both help work the rectus abdominis and obliques. But, crunches are the best when it comes to abdominal muscle isolation and having a targeted workout session.
For the core also, both sit-ups or crunches are effective. However, there are more advantages reserved just for crunches. Let us have a prompt look at them-
The Advantages of Crunches Are
- Inexpensive– Like sit-ups, crunches are also cheap and do not burden you to buy equipment. You need no gym membership to hit for crunches but just a yoga mat.
- Stabilize the Core– Yes, as we said earlier, sit-ups or crunches are exercises that help stabilize your core. But crunches enhance your daily lifting, twisting, and jumping movements.
- Better Abdominal Muscle Endurance– Now, this is something that is not common between sit-ups or crunches. A short-term study was conducted to learn training frequencies on abdominal muscles in untrained individuals. The six-week-long study divided the participants into 3 groups. Group one performed crunches twice a week, group two once, and group three did not do any exercises at all. There was indeed a significant increase in the abdominal endurance among the group that did crunches twice. On the contrary, the group that did it once had little improvement, and the group with no exercise experienced no change.
- Intense Muscle Isolation– Sit-ups or crunches both help gain muscle. But, unlike situps, crunches only work against the abdominal muscles. People who strive to achieve six-pack abs do count on crunches, though. The intense muscle isolation done by crunches also makes them desirable to strengthen the core, obliques, and lower back. What’s more? Crunches, just like sit-ups, help refine posture and overall body balance.
Disadvantages of Crunches
The big and prominent disadvantage associated with crunches is dramatically the same as their biggest advantage; working only on the abdominal muscles. Therefore, people who want to focus on particularly targeted groups may find it helpful. However, the ones looking for a multiple muscle group workout may avoid it.
Follow These Easy Steps to Gain The Correct Form For Crunches
- Lie down straight on the back.
- Bend your legs to stabilize the lower body.
- Cross your hands opposite on your chest till your shoulders. You can also keep your hands behind the ears, but of course, without pulling on your neck.
- Now, you have to lift off your head and shoulder blades from the ground carefully. While you rise, exhale.
- Then, as you finish one rep, lower the body. Breathe in while you get down.
- You can initially start with 10-25 reps in a single set and then go up after gaining strength.

The Final Word
Sit-ups or crunches, both exercises involve a great deal of range of motion. The main difference between the two, however, lies in their common and most prominent advantage. While performing crunches, one needs to reach the knees and slightly lift up off the ground. They are more like a targeted workout, focusing mainly on the abdominal muscle. But, that’s not the case when it comes to sit-ups. They involve more muscles than crunches and offer a broader range of movement. Interestingly, here, the advantage of sit-ups brings along the risk of injury.
Therefore, we can conclude that choosing between sit-ups or crunches is a subjective choice a person needs to make depending upon their fitness level and needs. Both the exercises share some set of similarities but still have their differences. You can consult a professional trainer if you are confused between sit-ups or crunches. It is vital to avoid injury or ensure correct form. If you’ve found the right one for you and performed it with the right form, share your experience with us in the comment section.
