IRA-Syllabus
This specialist workshop prepares fitness professionals to plan, demonstrate and supervise safe shallow-water exercise sessions for aerobic endurance, muscular strength, endurance, mobility, balance and general conditioning.
The programme focuses on apparently healthy adults. Clients with diagnosed medical conditions, recent surgery, pregnancy-related complications or significant functional limitations require appropriate medical clearance and individualised exercise prescription. Fitness professionals must work within their qualifications and must not diagnose, treat or rehabilitate medical conditions independently.
Module 1: Introduction to Water Fitness

Differences between water fitness, swimming and aquatic rehabilitation
Benefits and limitations of shallow-water exercise
Applications for:
- Aerobic conditioning
- Muscular strength and endurance
- Weight management
- Mobility and flexibility
- Balance and coordination
- Low-impact general fitness
- Active ageing
- Cross-training and recovery
Professional scope of a water-fitness instructor
When referral to a physiotherapist or medical practitioner is required

Hydration requirements despite reduced perception of sweating
Module 3: Exercise Screening and Assessment
Health-history and informed-consent forms
Exercise experience, swimming ability and confidence in water
Previous injuries, surgeries and falls
Medication review within professional scope
Identification of cardiovascular, respiratory, metabolic, neurological and musculoskeletal concerns
Resting heart rate and blood-pressure screening where appropriately qualified
Assessment of posture, mobility, balance and functional capacity
Establishing client goals and baseline ability
Determining when medical clearance is required
Preparticipation screening should consider current activity, known disease, symptoms, medication and the intended intensity of exercise. ACSM identifies screening, medical clearance and appropriate test selection as core responsibilities of exercise professionals. American College of Sports Medicine (USA).
Module 4: Aerobic-Endurance Training
4.1 Principles
Cardiovascular and respiratory responses to water exercise
Applying frequency, intensity, time and type—the FITT principle
Continuous, interval and circuit-training formats
Gradual progression of duration and intensity
Monitoring intensity through:
- Rating of perceived exertion
- Talk test
- Observation of breathing and movement quality
- Heart-rate monitoring, with awareness that water immersion can alter heart-rate response
4.2 Practical aerobic exercises
Water walking: forward, backward and lateral
Marching and power marching
Jogging and running
Heel digs and hamstring curls
Knee lifts and alternating knee drives
Side steps and grapevine variations
Jumping jacks and low-impact jacks
Cross-country skiing action
Rocking-horse movement
Front, side and back kicks
Shuttle movements and direction changes
Rhythmic combinations
Partner and group drills
Interval and station circuits
Programming should contribute to broader physical-activity goals. WHO recommends 150–300 minutes of moderate-intensity aerobic activity weekly for adults, together with muscle-strengthening activities on at least two days. WHO physical-activity guidelines
Module 5: Strength and Muscular-Endurance Training
5.1 Principles
Resistance created by water rather than gravity
Concentric muscular action in opposing directions
Stable stance and trunk control
Movement quality before speed
Progressive overload through:
- Increased movement speed
- Greater range of motion
- Longer lever arms
- Increased surface area
- More turbulent movement
- Added aquatic equipment
- Longer work periods
- Shorter recovery periods
5.2 Upper-body exercises
Chest press and reverse fly
Shoulder flexion, extension and abduction
Horizontal shoulder abduction and adduction
Water rowing
Lat pull-down action
Biceps curl and triceps press
Punching patterns
Diagonal pulls and presses
Internal and external rotation with controlled resistance
5.3 Lower-body exercises
Squats and wide-stance squats
Split squats and supported lunges
Hip flexion, extension and abduction
Hamstring curls
Knee extensions within a comfortable range
Calf raises
Step patterns
Leg presses against a noodle
Controlled kicks in different directions
5.4 Trunk conditioning
Standing trunk stabilisation
Anti-rotation presses
Controlled trunk rotation
Knee drives with abdominal bracing
Noodle-supported balance exercises
Contralateral arm-and-leg movements
5.5 Equipment
Foam water dumbbells
Pool noodles
Aquatic gloves and paddles
Resistance cuffs
Kickboards
Flotation belts
Equipment must be inspected, appropriately selected and introduced progressively. Foam dumbbells are buoyancy devices; attempting to “lift” them out of the water or forcing them underwater without control may overload the shoulders.
Module 6: Mobility, Balance and Cool-Down
Controlled joint-mobility exercises
Dynamic range-of-motion work
Supported single-leg balance
Weight shifting and multidirectional stepping
Coordination and reaction drills
Gentle static stretching
Breathing control and relaxation

Safe transition from water to the deck
Module 7: Medical Conditions, Precautions and Contraindications
Do not admit the participant into the session
Fever or acute systemic illness
Vomiting or diarrhoea
Contagious skin or waterborne infection
Uncovered open wounds or unhealed surgical wounds
Uncontrolled bleeding
Acute intoxication
New or unexplained chest pain
Severe breathlessness at rest
Fainting, confusion or unstable neurological symptoms
Uncontrolled seizure disorder
Medically unstable cardiac or respiratory disease
Inability to enter, exit or remain safe in the water with available assistance
CDC advises people with diarrhoea to stay out of pools and recommends excluding or fully protecting open cuts and wounds. CDC healthy-swimming guidance
Conditions requiring clearance and individual modification
| Condition | Principal precautions |
| Hypertension | Confirm control; avoid breath-holding and excessive intensity; monitor symptoms |
| Coronary disease | Medical clearance; loner warm-up and cool-down; stop for chest discomfort or unusual breathlessness |
| Heart failure | Clearance essential; immersion may increase central blood volume; monitor fatigue, breathing and swelling |
| Asthma or respiratory disease | Medication accessible; avoid irritating environments; monitor breathing |
| Diabetes | Check glucose-management plan; recognise hypoglycaemia; protect feet; keep medication and fast-acting carbohydrate available |
| Arthritis | Use comfortable depth and range; avoid forceful twisting and ballistic movement |
| Osteoporosis | Avoid uncontrolled spinal flexion, forceful rotation and high-impact jumping where inappropriate |
| Joint replacement | Obtain clearance; observe movement restrictions and safe entry and exit |
| Obesity | Ensure suitable depth, balance support, equipment capacity and safe steps or ramp |
| Pregnancy | Obtain obstetric guidance where indicated; avoid overheating, exhaustion and unsafe entry or exit |
| Neurological conditions | Assess balance, cognition, sensation and seizure history; provide close supervision |
| Kidney disease or transplant | Medical clearance; consider infection risk, fatigue, blood pressure and medication effects |
| Incontinence | Follow facility hygiene policy; bowel incontinence or active diarrhoea precludes pool participation |
| Skin disorders | Avoid participation when infectious, actively weeping or not safely covered |
| Visual or hearing impairment | Provide orientation, clear cues and additional supervision |
Module 8: Pool and Participant Safety
Pool-risk assessment before every session
Appropriate water depth and clearly marked boundaries
