Pilates: 5 simple exercises for a flatter stomach without punishing sit-ups

A flatter stomach without punishing sit-ups: a Pilates instructor shares a simple living-room routine that could bring visible changes after just a few weeks.

It is a familiar situation for many people: trousers feel tight, the stomach becomes bloated after eating, and traditional crunches leave the neck more sore than the abdominal muscles. This is where a targeted Pilates routine created by an experienced coach comes in. Using only a mat and a few minutes of time, these five focused exercises are intended to activate the deep abdominal muscles and make the waist appear more defined week by week.

Why Pilates can make the stomach look flatter

When people think about abdominal training, they often picture visible muscles – the classic “six-pack”. From an anatomical perspective, however, another muscle layer is especially important for a flat-looking stomach: the deep abdominal muscles.

Sports scientists broadly distinguish between:

• Superficial abdominal muscles – mainly the rectus abdominis and obliques, which bend and rotate the torso.
• Deep muscles – particularly the transverse abdominal muscle (transversus), which acts rather like an internal corset.

This “internal corset” is the focus of many Pilates movements. Instructors repeatedly stress the same sequence: exhale first, gently draw the stomach inwards and engage the pelvic floor – only then should the movement begin. This approach recruits not only the visible muscles but also the deeper supporting layer.

“Anyone who consciously draws their navel gently towards their spine while exhaling activates the deep abdominal muscles – that is the heart of the Pilates effect for a flatter stomach.”

There is another advantage: when the whole core becomes more stable, the lower back is relieved. Many people say their posture improves and their lower-back arch becomes less pronounced. As a result, the entire silhouette naturally looks longer and more elongated – even if the number on the scales has not changed.

The coach’s 5 favourite Pilates exercises for a toned core

From the wide range of available movements, the Pilates coach has selected five favourites. They can all be done at home without equipment, preferably on a non-slip mat:

• Single Leg Stretch
• Double Leg Stretch
• Double Leg Lower Lifts
• Shoulder Bridge with Kick
• Scissors

Single Leg Stretch: an introduction to deep core engagement

Start lying on your back. Pull both knees towards the chest, lift the head and shoulders slightly, and look towards the thighs. Next, extend one leg forwards while keeping the other knee drawn in. Switch legs in a smooth, continuous movement.

• Activates: transverse and oblique abdominal muscles
• Training effect: maintains core engagement and improves body control
• Tip: keep the movement smaller if necessary and press the lower back firmly into the floor

Double Leg Stretch: a classic all-round Pilates movement

For this exercise, lie on your back again with your head and shoulders slightly raised. Begin with the arms and legs close to the body. As you inhale, extend the legs forwards and reach the arms back overhead; as you exhale, return both towards the centre.

Although the movement appears straightforward, it challenges the whole core because the arms and legs function as counterweights. With controlled breathing, it quickly becomes clear how hard the deep muscles must work to keep the back stable.

Double Leg Lower Lifts: targeting the lower stomach

This variation noticeably works the area below the navel. From a supine position, raise both straight legs upwards into roughly a “V” shape. Slowly lower them towards the floor before lifting them again.

“The more controlled the lowering phase, the harder the lower stomach has to stabilise – this makes clear why precise technique matters more than a large range of movement.”

The key point is that the lower back must remain heavy against the mat throughout. If it begins to arch away from the floor, reduce the range of motion or take a break.

Shoulder Bridge with Kick: a bridge for the glutes, back and stomach

The classic shoulder bridge strengthens the glutes and the backs of the legs. Adding a kick in this Pilates variation brings extra core work into the movement. Begin on your back with feet hip-width apart and knees bent. Lift the pelvis until the thighs and upper body form a straight line.

Then extend one leg upwards towards the ceiling and lower it back in a controlled kick to the level of the opposite knee. Keep the hips as steady as possible and avoid letting them drop to one side. Maintaining this stability works the entire core almost without you noticing.

Scissors: for hip mobility and a strong core

Scissors introduces more movement. Lying on your back, take both straight legs up towards the ceiling. Lower one leg towards the floor while drawing the other upwards. Keep the stomach actively pulled in with every change.

Many Pilates teachers use small pulses here: the raised leg is assisted with two small pulling movements while the breath is deliberately controlled. Anyone with neck discomfort can leave their head and shoulders on the floor and focus fully on the core.

How to fit the routine realistically into daily life

The coach suggests following a set order so that you do not have to spend time deciding what to do:

1. Single Leg Stretch
2. Double Leg Stretch
3. Double Leg Lower Lifts
4. Shoulder Bridge with Kick
5. Scissors

At the beginning, eight to ten repetitions of each exercise are enough. Keep the pace relatively slow, concentrating on breathing and control. If you are new to the routine, take a short breather between exercises rather than forcing your way through them as though they were a test of strength.

Some users report noticeable changes after around three weeks: more firmness through the stomach, a lighter feeling in the morning and less pulling in the lower back. What matters is consistency and sound technique – not achieving a perfect figure in record time.

Living room rather than studio: creating a Pilates space at home

According to instructors, anyone who does not want to attend a class can manage perfectly well at home with a few basics. Initially, all that is needed is a non-slip surface, comfortable clothing and bare feet. Certain variations can also make use of household items:

• Non-slip socks or small towels on a smooth floor for gentle sliding movements
• A folded towel to support the head or pelvis
• A yoga cushion or firm cushion for people with a sensitive back

If you exercise on parquet flooring or tiles, make sure nothing can slide away. A firm surface with a little give is ideal. Also, stop immediately if an unusual sharp pain occurs and seek medical advice if in doubt.

When the first results appear – and what affects them

Many personal accounts mention around 21 days as a rough guide before something starts to feel “different”: the stomach looks flatter in the morning, trousers fit more comfortably and everyday movements feel easier. That timeframe is not a promise, however.

Factors include:

• How regularly the exercises are actually performed
• How consistently breathing and technique are followed
• Sleep, stress levels and diet
• Pre-existing conditions or long periods without exercise

“Anyone who trains consciously three times a week, uses deep breathing and does not constantly exercise on a full stomach has a much better chance of visible changes.”

Is Pilates suitable after 60? What older people should consider

Pilates is generally regarded as gentle on the joints, which is why it is often recommended for people over 60 too. However, instructors set out several clear guidelines for this age group:

• Keep the range of motion smaller; controlled movement is preferable to moving far
• Allow plenty of breaks and keep an eye on pulse and breathing
• Seek medical clearance in advance if you have heart or back problems
• Stop if dizziness, breathlessness or sharp pain occurs

Especially later in life, the combination of better core strength and improved mobility can help to prevent falls. Many people also report feeling steadier when walking and using stairs.

What terms such as “deep abdominal muscles” and “Pilates breathing” mean

People starting Pilates often hear terms that can sound abstract at first. Two come up particularly often in connection with a flatter-looking stomach:

• Deep abdominal muscles: This mainly refers to the transverse abdominal muscle. It wraps around the torso like a broad band and helps support the organs and spine. When it is engaged, the stomach draws in slightly in visual terms.
• Pilates breathing: This describes a breathing pattern in which the ribs expand sideways and towards the back while the stomach stays relatively flat. On the exhale, the core actively contracts, increasing the training effect.

Anyone who understands and can feel these two concepts will get considerably more from each of the five exercises. The aim is not to exhaust yourself, but to consciously engage the “internal belt” with every repetition. That is precisely what makes this routine appealing to anyone hoping to tone their stomach without overloading their back.
