Turning 40 does not mark the start of an inevitable physical decline. It marks the moment the body starts asking for smarter exercise. And Reformer Pilates is precisely that: smart exercise.
If you have been thinking for a while about starting or getting back into physical activity but do not know where to start, this article is for you. Here you will find an honest explanation of what changes in the body after 40, why the Reformer responds to those changes better than any other discipline, and how to start safely and sustainably.
What Changes in the Body after 40
Understanding what happens physiologically from 40 onwards is not alarmist. It is necessary in order to choose the type of exercise that suits you best.
The Metabolism Slows Down
From 40, the basal metabolic rate declines progressively. The body burns fewer calories at rest, which makes it easier to accumulate body fat even if eating habits have not changed. Doing more intense exercise is not always the solution: without the right strength work, the effect can be counterproductive.
Muscle Mass Decreases
Sarcopenia, that is, age-related loss of muscle mass, starts to make itself felt from 40. From that decade on, the body can lose between 3 and 5 per cent of its muscle mass every ten years if it is not actively worked to preserve it. Less muscle means less strength, less joint stability and an even slower metabolism.
The Joints Become Stiffer
The collagen that lubricates and protects the joints loses quality with age. Morning stiffness becomes more frequent, ranges of motion shrink and the risk of injury increases if exercise is not well calibrated. The repeated impacts the body tolerated at 25 cause growing discomfort at 45.
Recovery Takes Longer
Muscle and connective tissue take longer to regenerate. Workouts that used to be strung together without any problem now require more recovery time. Ignoring this signal leads to overuse injuries that can become chronic.
Hormonal Changes: Perimenopause in Women
For many women, turning 40 coincides with the start of perimenopause, the transition towards menopause. The progressive drop in oestrogen affects mood, sleep quality, body weight, bone density and temperature regulation. These changes are not minor: they call for a type of exercise that takes them into account.
Why 40 Is the Perfect Time to Start Pilates
None of the above is a barrier. It is a map. And Reformer Pilates is one of the few exercise methods designed to navigate that map effectively.
The belief that it is “too late” to start a new physical practice is one of the most widespread and least justified myths. The adult body has a remarkable capacity to adapt when it is given the right stimulus. The key is for that stimulus to be intelligent, not simply intense.
At 40, many people have something they did not have at 20: body awareness, consistency and real motivation. These three qualities often make progress in Reformer Pilates faster and deeper than in younger people who arrive without that maturity.
Reformer Pilates does not require the body to be perfect in order to start. It starts from wherever each person is and builds from there.
Why the Reformer Is the Best Exercise Option from 40 Onwards
There are many ways to move. But not all of them are equally suitable for a body of 40 or more. These are the reasons why the Reformer stands out from other options.
Low Joint Impact
The Reformer machine works with a system of springs and pulleys that generates resistance without impact. The joints do not absorb repeated shocks as they do with running or jumping. This allows you to strengthen the body progressively without wearing down cartilage or irritating already sensitive joints.
Intensity Adjustable to Your Level
The Reformer springs allow the resistance to be changed in a matter of seconds. This means the same exercise can be gentle for someone just starting and challenging for someone with years of practice. Progression is gradual, measurable and always appropriate to where you are.
It Builds the Muscle Mass the Body Loses with Age
Reformer Pilates works with resistance, and resistance is the stimulus the body needs to preserve and develop muscle mass. It is not about visible muscle bulk, but about functional muscle tissue that stabilises the joints, supports the spine and keeps the metabolism active.
It Corrects Decades of Poor Posture
Thirty or forty years of office work, of driving, of looking at screens, leave their mark on the body. Rounded shoulders, a stiff thoracic spine, shortened hips. The Reformer works systematically to rebalance those muscles and recover an alignment the body no longer remembers how to hold on its own.
Controlled Movements That Reduce the Risk of Injury
Unlike free or high-intensity exercise, Reformer Pilates is always performed with control, precision and awareness. There is no running, no jumping, no sudden movements. Every exercise has a defined execution that protects the structures of the body instead of putting them at risk.
Specific Benefits for Women in Perimenopause and Menopause
Women going through perimenopause or menopause find in Reformer Pilates a support tool that goes far beyond conventional physical exercise.
Bone Density
The drop in oestrogen accelerates the loss of bone density. The resistance work of the Reformer stimulates bone tissue formation, which helps slow that loss. If you want to know more about how Pilates addresses bone health, you can read our article on osteoporosis.
Mood Stability
Regular exercise regulates the production of serotonin and endorphins, two neurotransmitters that are key to emotional balance. In a changing hormonal context, this regulation can make a real difference day to day.
Body Weight Control
The muscular work of the Reformer activates the metabolism in a sustained way. It is not an immediate effect, but a cumulative one: with regular practice, the body burns more calories at rest because it has more active muscle tissue.
Better Sleep
The impact of Reformer Pilates on sleep quality is one of the benefits most valued by those who practise it. If this topic interests you, you can go deeper in our article on Reformer Pilates for better sleep.
Specific Benefits for Men from 40 Onwards
Men also find in Reformer Pilates concrete answers to their needs from 40 onwards.
Chronic Back Pain
Low back pain is one of the most frequent reasons men come to the Reformer. Years of intense sport, of physical work or simply of sedentary life end up creating chronic tension in the lumbar area. The Reformer works the deep muscles that stabilise the spine, relieving the pain at its cause and not just the symptom.
Recovering Mobility
Stiffness in the hips, hamstrings and thoracic spine is very common in men from 40 onwards. This lack of mobility limits everyday movements and increases the risk of injury in any sporting activity. Reformer Pilates works on range of motion progressively and safely.
Preventing Sports Injuries
Many men who keep playing sports such as tennis, padel, cycling or football after 40 find that the Reformer helps them maintain their performance and reduce injuries. The functional strength, motor control and stability that Pilates develops transfer directly to any sport. You can read more about this in our article dedicated to Reformer Pilates for men.
How to Start Safely at 40 or Older
Starting well makes the difference between a sustainable practice and one that ends in frustration or injury. These are the keys to starting Reformer Pilates from 40 onwards with good judgement.
Start at the Basic Level, Whatever Your Fitness
Even if you have played sport for years, Reformer Pilates uses movement patterns and activates muscles you have probably never worked before. Starting at the beginner level is not a step backwards: it is building a solid foundation that will make everything that comes afterwards more effective.
Communicate Your Limitations from the Start
If you have chronic pain, recent surgery, previous injuries or specific conditions such as osteoporosis or cardiovascular problems, tell your instructor before the first class. At Pinar Pilates, with a maximum of 8 people per class, personalised attention is possible and is part of the method.
Prioritise Consistency over Intensity
Two or three classes a week practised consistently produce far better results than five classes a week for two weeks followed by a month of absence. The body learns and adapts through repetition. Regularity is the most important factor.
Do Not Compare Your Progress with Others
Every body arrives with its history, its compensations and its own timing. Progress in Reformer Pilates is not measured by comparing what the person on the next Reformer is doing, but by noticing how your own body gains control, strength and ease as the weeks go by.

Frequently Asked Questions about Reformer Pilates after 40
Is it too late to start Pilates at 40 or 50?
No. There is no age beyond which the body stops responding to exercise. Scientific research shows that muscle and connective tissue retain their capacity to adapt well into the 60s and 70s. The only requirement is that the exercise be suitable for each person’s stage. Reformer Pilates is designed exactly for that.
How many times a week should I practise to see results?
Two sessions a week are enough to start noticing changes. Three sessions a week speed up progress significantly. The key is not the number of classes in any given month, but consistency over the months.
Can I practise Reformer Pilates if I have knee or hip pain?
In most cases, yes. The Reformer is one of the most widely used methods in physiotherapy and rehabilitation precisely because it allows you to work around an affected joint without overloading it. It is important to tell the instructor about any specific discomfort so they can adapt the exercises. If the situation is more complex, you can also see our article on Reformer Pilates for the over-50s.
Does Reformer Pilates help with weight loss?
Reformer Pilates is not a high-intensity cardiovascular exercise, so that is not its main function. However, it contributes to weight control indirectly: it increases muscle mass, which raises the basal metabolic rate; it improves body composition; and it reduces cortisol, the stress hormone that encourages abdominal fat storage. Combined with good eating habits, the effect on weight is real and sustainable.
Is there any condition that prevents you from practising Reformer Pilates?
The absolute contraindications are few: acute fever, high-risk pregnancy without medical supervision, or unstabilised injuries in the acute phase. In all other cases, with the right adaptation, Reformer Pilates can be practised. We always recommend consulting your doctor if you have specific doubts about your situation.
