Sit-Ups For Seniors – Should You Do Them?

Welcome friend! In this article, you will learn all about sit-ups for seniors. Should you do them? Are They good for you? Are there better options? Learn all this and more!

Sit-ups are probably the most common and well-known strength training exercise there is.

After all, it’s not that uncommon to hear people start doing a ton of sit-ups when they decide to get in shape and lose the middle-age spread.

Unfortunately, sit-ups are not effective if you want to lose belly fat for several reasons.  I’ll talk more about that a bit later on.

So what are sit-ups good for? They are a strength training exercise so they are more effective in improving your core strength. They can also help you maintain and build muscle mass.

But there is one big problem with sit-ups for seniors. For starters, people have very different ideas about how they are performed.

Secondly, many sit-up variations can be hard on your back. This is more of a concern for seniors, who often have back problems.

So are sit-ups a good ab exercise for you? Read on to find out.

What Are Sit-Ups

Sit-ups are strength exercises that are generally used to improve and measure abdominal strength. You’ve likely done them at least in school PT class as a fitness test.

There are many variations of sit-ups and all of them don’t target your abdominal muscles especially well. As the name suggests, you perform sit-ups by sitting up from a lying position.

In the typical sit-up, you lay on your back with your hands behind your back. Your legs are bent from the knee and your feet are flat on the ground. Your feet can be supported or unsupported.

You then raise your upper body off the ground by flexing your abdominals and the hips. In a typical sit-up, the aim is to touch your knees with your elbows.

If your feet are supported by another person or a couch for example a large portion of the exercise is actually performed by your hip flexors muscles instead of the abs.

That doesn’t mean that sit-ups are an ineffective strength training exercise though. The hip flexors are often neglected, tight and weak so they benefit from this type of exercise.

A common variation to sit-ups is including rotation to better activate your obliques.

The sit-ups can also be made harder for advanced bodyweight training by extending your arms above your head and straightening your legs.

This adds a lot of leverage to the movement making it a lot harder for you to perform. You might know this variation as jackknife sit-ups.

Problems With Sit Ups For Seniors

So sit-ups are an effective ab exercise but are they good for you if you’re a senior? Well, it depends.

The biggest problem with the sit-ups for seniors is that virtually all full-range variations require some flexion of your lumbar spine.

As you age your spine tends to lose mobility. The elastic discs between your spinal vertebrae degrade and compress.

This can lead to severe back pain but for most people, it simply means that your spine becomes stiffer.

If the discs deteriorate too much nature has perfected a solution to stabilize your spine. Your vertebrae will fuse together through bone formation.

This prevents any movement between your vertebrae making it a stiff structure. But this will protect the nerve inside your spine.

Sometimes these fusions have to be done surgically to avoid pain and neural pain. I’m sure you know someone who has had a back fusion operation.

There are also many inflammatory diseases like arthritis, connective tissue, and muscle problems that can make your back stiff and painful as you age.

What I’m getting at is that a stiff spine doesn’t really like to be flexed. This inevitably happens when you perform sit-ups.

This can lead to irritation of your spine, leading to pain ranging from mild to severe.

I want to make it clear that this is highly individual. Some seniors have no problem with sit-ups but many do. So if you want to do them, be aware that they can strain the lower back and if you get any issues it’s better to try something else.

Fortunately, there are a lot of good options for sit-ups.

Modified Sit-Ups For Seniors

A common variation of the sit-up is also known as a crunch. It’s essentially the first portion of the sit-up without the hip hinge.

In crunches, you simply lie on your back like in a sit-up. Instead of sitting up completely, you flex your abdominals to lift your head and upper back off the ground.

Here’s a great demonstration of the sit-up by YouTube channel (YouTube embed, content not owned or created by

To make to exercise more effective you can do a small pause at the top position. You should feel a really good activation in your abdominals this way.

The crunch is a good variation of the sit-up for seniors because it doesn’t flex your lumbar spine. Your lower back stays flat on the ground.

The crunch also activates your abdominals very well. Better than sit-ups in fact. So it’s very effective for building abdominal strength and muscle mass.

Even though the crunch doesn’t flex your lumbar spine, it does flex your thoracic spine. The thoracic spine is the middle and upper portion of your back.

If you have any issues with your thoracic spine the same problem applies as with sit-ups. Fortunately, the thoracic spine degenerates typically slower with age than the lumbar spine because there is less weight on the discs.

Why Core Strength Is Important For Seniors

The reason you should aim to improve core strength as you age is to keep your back healthy and pain-free.

Many people think of “the core” as abdominals but it actually includes your whole midsection and can be considered to include your hips as well.

The main function of your core musculature is to support your spine and to transfer force between your limbs and whole body as you move and lift things.

A weak core can lead to back problems and pain but it can also affect the functioning of your joints.

Abdominals are a crucial part of the core as they are weak in many people. So improving ab strength definitely beneficial for you.

But it’s important to strengthen the back musculature as well as the hips and the legs.

Fortunately, if you can’t do sit-ups or crunches, there are other effective ab and core strength exercises for seniors. Planks are a good option, as I talked about in the article Planks For Seniors.

Core strength is also very important for your balance and posture. Balance exercises and posture exercises are a great way to improve your core stability.

Sit-Ups For Seniors And Belly Fat

If you want to do sit-ups to lose belly fat I have good and bad news for you. The bad news is that you can’t lose belly fat with sit-ups or with any exercise really.

The good news is of course that you don’t have to do sit-ups to lose belly fat. Exercise is important when you are trying to lose weight because it helps you maintain muscle mass.

But the scientific truth is that you can’t spot-reduce fat and you can’t lose fat without being in a caloric deficit. Meaning that you need to eat less than you consume.

If you don’t exercise, your body will burn muscles alongside your fat stores. This can be detrimental for seniors if you reduced muscle mass.

The most effective way you can lose belly fat is by eating a healthy diet with a slight reduction in calories while keeping active.

Daily exercise and activities will slightly increase your energy expenditure but the diet is much more important.

I wrote more about fat loss in the articles Exercises For Belly Fat For Seniors, Weight Loss For Seniors, and Flabby Arm Exercises For Seniors.


I hope you found this article about sit-ups for seniors useful. If you have any questions, ideas or suggestions feel free to leave them in the comments below. I do my best to help my readers out!

As a recap: Sit-ups are a simple and effective abdominal exercise but they have a few problems for seniors.

They can irritate your back as they require rounding of your lower back. You might not be able to even perform them because of this.

Core and abdominal strength are very important for your health and the functionality of your body.

Fortunately, there are other ab and core exercises besides the situps that don’t require rounding your lower back.

If you want to do a simple and effective variation of the sit-up for seniors, crunches are likely your best option. They don’t require lower back flexion and activate the abs very well.

Thanks for reading and see you next time!

  1. Hi. I’ve just started looking at your website and I’m finding it very interesting. I’m 70 years old and I need to lose some weight and get on a healthy diet consistently, along with exercise. Thanks.

    • Glad to hear you like the content Jeff! And great to hear you’ve decided to get in shape. Remember that a little goes a long way and forming healthy habits is much more important than strenuous workouts. Good luck!

  2. I love it! I am 72 years old and suffer from lower back pain along with my piriformis syndrome. Many years ago, I had a fracture in my lumbar region which laid me up for 6 weeks. The fracture probably was the result of overuse and improper muscle training, ie., lack of core strength at the time. I have been careful not to re-injure the area, and sit-ups have always seemed inappropriate to me. Your advice and support reinforces my belief in crunches over sit-ups, and now I don’t have to feel as if I am under-performing because I simply don’t like sit-ups, but many people consider them so essential to strength.
    Thank you!

    • Glad to hear you found it useful Sharon! It’s definitely possible to strengthen the abs and core without sit-ups. In fact, I think sit-ups are why most people hate training the abdominals or even strength training in general. They are just uncomfortable and for most people also ineffective. That said, they are one of the few effective exercises that people actually use to strengthen their hip flexors, unintentionally though 🙂
