How Do I Become a Fitness Instructor for Special Populations?

To become a fitness instructor for special populations, you need to complete a level 2 gym instructor qualification before continuing professional development with a specialist level 3 or level 4 course.

A fitness instructor for special populations acts as an extension of the healthcare system, bridging the gap between healthcare services and the needs of the population. In order to do so, a fitness instructor needs to develop the skills, knowledge and attributes required to work with special populations safely and efficiently. This is done through specialist qualifications, continuing professional development and hands-on experience. 

Special populations cover an array of different groups, including those with temporary or chronic health conditions. The most common special populations covered in fitness courses include: 

• People with disabilities 
• Obesity and diabetes 
• Lower back pain 
• Pre and post natal women 
• Older adults 
• Children and adolescents 

People within these groups may have unique needs when it comes to exercise, they will also likely face specific challenges and barriers to exercise, that those within these categories do not. Becoming a fitness instructor for special populations will allow the individual to understand these needs and barriers and find suitable methods for coaching certain clients. 

In this article, we will go into more detail about the different special populations, the qualifications required to coach them and career development for fitness instructors who want to pursue a career working with a specific population.

Understanding Special Populations

We’ll take a look at the most common special populations and their needs and challenges when it comes to physical activity. 

People with disabilities 

By law, someone is defined as disabled if they: 

• Have a physical or mental impairment. 
• The impairment has a substantial and long-term adverse effect on their ability to carry out normal day-to-day activities. 

Examples of physical or mental impairments include: 

• Down syndrome 
• Cerebral palsy 
• Multiple sclerosis 
• Visual or auditory impairments 

Under the Equality Act (2010), discrimination is prohibited against anyone with protected characteristics noted within the act, this includes people with disabilities. 

Unique needs and challenges faced by people with disabilities 

Unfortunately, the fitness industry does not have a brilliant track record when it comes to making spaces accessible for people with disabilities. According to Disability Rights UK, only 67 out of nearly 7500 gyms are accredited by the activity alliance’s inclusive fitness initiative, proving their commitment to making gyms accessible. People with disabilities are twice as likely to be physically inactive (41%) compared to those without a disability (20%), highlighting the need for more accessible spaces and fitness instructors for special populations. Some of the main barriers to exercise include: 

• Cost: There is a large disparity between those with and without disabilities in relation to the income gap in the UK. Gyms come at a cost, which might not be financially viable for those in a lower income bracket. 
• Access: Not all gyms and changing spaces are accessible for those with disabilities. For example, if they are wheelchair friendly and have machines that allow users to access them without leaving their chair. There are also items such as voice-activated machines for people with visual impairments. 
• Lack of training: Staff in gym facilities need training in order to be confident and knowledgeable when working with people with disabilities. This is why training is vital if you want to become a fitness instructor for special populations. 

Children and adolescents 

Anyone under the age of 18 is classed in the UK as a child or adolescent. These are people who are still under the protection of a legal guardian. A fitness instructor’s role working with this population is to provide safe access to physical activity that meets the needs of a population who have different motivation and interests to those of an adult. 

Unique needs and challenges faced by children and adolescents 

A 2015 study found that only 14% of male and 8% of female 13-15 year olds were meeting the UK physical activity guidelines. This not only has an impact on their livelihood during teenage years, but can also negatively impact adulthood, as children who are obese are more likely to be obese adults. There are several reasons why children and adolescents aren’t participating in activity, one of the biggest reasons cited being a lack of confidence and self-consciousness.

As a fitness instructor for special populations in this sector, it is important to not only help adolescents correctly participate in physical activity, but also make them feel comfortable and confident in these environments to promote healthy habits later on in life. As well as a lack of confidence, the needs and challenges faced include: 

• Fun and engaging activities: Children and adolescents are not usually driven by the desire to exercise for health and longevity like adults are. Hence why it’s important to factor ‘play’ into physical activity to make it more fun and boost the appeal for participation. 
• Access to space for exercise: Those living in urban and town settings may have less access to outdoor areas and facilities specifically for exercise. 
• Change in physical appearance: Growth spurts and hormonal changes can have both a mental and physical impact on adolescents and therefore their desire to participate in exercise. 

 

Pre and post natal-women  

The prenatal period is more commonly known as pregnancy and is the nine months leading up to childbirth. The post-natal period is less specific. Many healthcare providers categorise it as 6-8 weeks after birth. However, any woman who has experienced childbirth is classed as ‘postnatal’. This is because the effects of pregnancy and childbirth can be long-lasting and may have a mental and/or physical effect on the woman for the rest of their life. For example, diastasis recti (muscle separation of the core) can continue for years after birth if not corrected by physiotherapy or surgery. 

Unique needs and challenges faced by pre and post-natal women 

The pre and post-natal period is incredibly rewarding for women, but they face significant challenges when it comes to physical activity. Until recently, the exercise guidelines for this population were sparse, and many were not equipped with the knowledge on how women should train during this period. Fortunately, although the research doesn’t tell us everything, there is a growing body of evidence highlighting the benefits of exercise for pre and post-natal and more nuanced guidelines for the demographic. Some of their main needs and challenges include: 

 

• Physiological changes: During pregnancy, there are several physiological changes that have a significant impact on a woman’s body and how she can exercise. This can make certain types of exercise more difficult and even unsafe to perform. Post-childbirth, changes in the core and pelvic floor muscles can also impact a woman’s ability to exercise. 
• Psychological changes: Pregnancy and the surge of hormones can have an effect on emotional health and fatigue levels. This might make women less motivated to exercise. Post-birth, sleep is often lacking which can reduce the desire to train. Likewise, many women are faced with ‘guilt’ of choosing to exercise instead of spending time with their children and post-natal depression can also hugely impact a woman’s mental health. 
• Adjusting to a new life: Many women have commented that it can be a challenge adjusting to a new lifestyle. Priorities often include caring for the child, partner and housework, with exercise becoming less of a priority. 
• Accessibility: Women might not have the time to exercise, especially if they don’t have other adults to help care for their children. Likewise, exercise classes can become expensive and might not be viable, especially during maternity leave when many women take a cut in their pay. 

Older adults 

In the UK, older adults are defined as adults over the age of 65, however the physical activity needs and demands differ for each individual depending on their circumstances. Remaining physically active into older age is extremely important, as it can help reduce the risk of injuries and illnesses that are more likely when we are older, including osteoporosis and heart disease. A fitness instructor for special populations in this sector can have a huge impact on older adults quality of life.

Unique needs and challenges faced by older adults  

For most older adults, the priority of exercise is to improve strength and mobility to make daily living easier. With this in mind, training doesn’t need to be focused on maximal strength, but a combination of exercises that will increase strength and muscle tone, as well as helping them move around more easily. 

• Focus on social: As people age, there is a chance that they see less and less people, especially if they are not as mobile and able to leave the house often. Therefore one of the main needs of exercise for older adults is the social aspect, getting out and communicating with others.  
• Reduced intensity: There is an increased chance that an older adult will have weaker bones and muscles, especially if they haven’t participated in strength training before. With this in mind, it’s important to reduce the intensity of the workout to ensure too much strain isn’t being placed on the body.

Required Qualifications and Certifications

To specialise as a fitness instructor for special populations, you are first required to qualify as a level 2 gym instructor or an equivalent. With this qualification, you can then progress to qualify as a specialist with level 3 qualifications. As well as passing your level 3 Personal Trainer, you can also undertake several specialist courses. 

Once qualified, you can then pursue a career as a fitness instructor for special populations. Some of the most popular special population courses include:  

• Level 3 CIMSPA Accredited Pre and Post Natal 
• Level 3 Exercise Referral 
• Level 2 Leading Physical Activity for Adolescents 
• Coaching older adults course

There are some courses that require a higher level of education in order to enroll. Once completing a Level 3 Personal training diploma, you can then continue to pursue the following: 

• Level 4 Lower Back Pain Specialist 
• Level 4 Obesity and Diabetes 

As well as completing structured formal courses, you can develop your knowledge by continuing professional development. Whilst this may take the form of other courses focused on special populations, there are plenty of other ways you can learn, such as: 

• Reading academic research 
• Workshops and seminars 
• Reading reputable books and articles 
• Shadowing more experienced specialists 
• Working with a mentor

If you’re serious about becoming a fitness instructor for special populations, the best thing you can do once you’re qualified is work with people and gain as much experience as possible. With hands on experience, you’ll have a better understand of the overarching and individual needs of people within that population. You will also understand how as a fitness instructor, you can work to meet their needs and help them overcome their barriers.

Adapting Exercise Programs for special populations 

For each of the special populations, there will be specific principles fitness instructors are required to follow in order to meet the needs of their client. For special populations in general, here are some principles that should be followed as guidance when planning a program: 

Universal design 

When planning an exercise program, make it as accessible and usable as possible for people with a range of physical and mental abilities. This is especially important when working in a group environment, such as a class. All of the exercises need to be suitable for everyone participating in the class to avoid exclusion. In a class, you might need to bring in additional adaptive equipment for someone with a disability.

Individualisation

If you’re working with a client on a one-to-one basis, regardless of whether they are a special population or not, your training program should be individualised to meet their needs and goals. For example, if an older adult has certain mobility issues, you will need to design a program that addresses these and focus on improving their mobility. 

Modifications 

Modifications can come in the form of making small adjustments to certain exercises, all the way through to completely changing the session to meet the client’s needs at the time. For example swapping out hip thrusts for a pregnant client who is training in their third trimester and cannot lie on her back vs another pregnant client who has not slept well and so needs to reduce the volume and intensity of the whole session. 

Progressive overload

When planning a program, progressive overload is essential for anyone to make progress. For people in these special populations, progressive overload is still a necessity, but the range of change might be different. Gradual increases in intensity should be based on ability and constant monitoring of progress. For example, for an adolescent who is focusing on skill development, for a long period of time, the weight used might not change, but they progress as they improve their technique each week. 

These are just a few of the general principles that should be followed when developing a program for a client within a special population. First, the fitness instructor should carry out an assessment to understand more about the client’s needs and goals and determine their injury and exercise history. From here, they will be able to help the client set realistic and individualised goals.

Collaboration with Healthcare Professionals

Before starting any exercise program with someone from a special populations, it’s important that they get medical clearance from a professional. This is to ensure that they are safe to participate in exercise, and also ensures that your insurance is valid. This medical clearance should be written down and signed, then safely kept. 

Importance of multidisciplinary teamwork and referrals

For someone working as a fitness instructor for special populations, it can be extremely beneficial to work within a multidisciplinary team to ensure the safety of your client. It is vital that you remain within your scope of practice, and if something is beyond your knowledge, you signpost and refer on to the correct professional. Examples of a multidisciplinary team for a prenatal client include: 

• Nurse or midwife 
• Pelvic floor physiotherapist 
• Dietitian 

Contraindications 

A contraindication is a condition or factor that serves as a reason to potentially stop physical activity in case it puts the client at harm. There are two different types of contraindications: 

Relative contraindications: Conditions where exercise may be performed with caution, often at lower intensity or with modifications, and typically under medical supervision. Examples include moderate to severe aortic stenosis, recent stroke, resting hypertension above certain thresholds, or certain blood abnormalities.

Absolute contraindications: Situations where exercise should not be performed under any circumstances until the condition is treated or managed. Examples include acute myocardial infarction, unstable angina, uncontrolled arrhythmias, severe heart failure, acute infections with fever, deep vein thrombosis, and recent serious musculoskeletal injuries.

Contraindications for pre and post natal women: 

Absolute contraindications

• Ruptured membranes
• Active preterm labour
• Unexplained PV bleeding
• Placenta praevia after 28 weeks
• Severe pre-eclampsia
• Incompetent cervix
• Intrauterine growth restriction
• Higher-order multiple pregnancy (e.g., twins, triplets etc.)
• Uncontrolled high blood pressure, type 1 or type 2 diabetes or thyroid disease
• Uncontrolled or severe arrhythmia
• Other serious cardiovascular, respiratory or systemic disorders

Relative contraindications

• Mild/moderate cardiovascular or respiratory disease
• Well-controlled type 1 diabetes
• Mild pre-eclampsia
• Preterm premature rupture of membranes
• Untreated thyroid disease
• Multiple nutrient deficiencies/ malnutrition
• Symptomatic severe eating disorder
• Placenta previa after 28 weeks
• Moderate to heavy smoking (>20 cigarettes per day)
• Other significant medical conditions

General contraindications for any clients and special populations:

Absolute contraindications: 

• Acute myocardial infarction (MI), within 2 days
• Ongoing unstable angina
• Uncontrolled cardiac arrhythmia with hemodynamic compromise
• Active endocarditis
• Symptomatic severe aortic stenosis
• Decompensated heart failure
• Acute pulmonary embolism, pulmonary infarction, or deep vein thrombosis
• Acute myocarditis or pericarditis
• Acute aortic dissection
• Physical, mental, or emotional disability that precludes safe and adequate exercise

Relative contraindications: 

• Known obstructive left main coronary artery stenosis
• Moderate to severe aortic stenosis with uncertain relation to symptoms
• Tachyarrhythmias with uncontrolled ventricular rates
• Acquired advanced or complete heart block
• Hypertrophic obstructive cardiomyopathy with severe resting gradient
• Recent stroke or transient ischemic attack
• Mental impairment with limited ability to safely cooperate
• Resting hypertension with systolic or diastolic blood pressures > 200/110 mmHg
• Uncorrected medical conditions, such as significant anaemia, important electrolyte imbalance (eg, hypokalemia), and hyperthyroidism.

If a client mentions any of the above contraindications in a consultation or before a workout, it is essential that they receive medical clearance from a GP or medical professional. If not, you may not be insured if anything happens to that individual during their training session. If you’re ever in doubt, ask them to get medical clearance just incase.
