POOL OPERATORS · SHALLOW WATER AQUA FITNESS

Your pool has an empty hour. This is what fills it.

A 45-minute music-led shallow-water class for older adults, run in your existing pool in an off-peak slot. Participants stand on the floor and work at the wall, water walking, wall work and strength against drag, to a soundtrack, in a group that comes back. The wall is the apparatus. Nothing is installed, nothing is hired, and the shallow end is back to public use the minute the class ends. What you buy is occupancy: a standing weekly booking in a slot that is currently water, with the attendance counted and reported to you.

01 · SUMMARY

Shallow Water Aqua Fitness at a glance

Participants
Older adults, no swimming ability and no experience required. The people who will not join a land class: sore joints, replaced hips and knees, a fear of the footpath. Alongside the people who simply like the water and the music.
Session
45 minutes, nine tracks in five blocks, entered and exited by the steps one at a time
Group size
Capped at 10, instructed from the deck
Frequency
Once weekly; twice weekly where the slot allows. The dose section explains why
Block
12 weeks, delivered as two six-week blocks. The interval between the entry measures and the re-measure
Venue
Your shallow end and your wall at 26–30 °C, in an off-peak slot, assessed against a written checklist before the first session
Equipment
None installed. A speaker, webbed gloves and a stopwatch, brought and taken away
Measurement
Attendance and retention per session and per block, plus four functional tests on the deck at week 1 and week 12, reported in writing

Why none of the three GlenCook.FIT programs needs capital spend

Outdoors the apparatus is the bench and the rail already on the path. In a village activity room it is the chair already in the room. In the water it is the pool wall. Every program is built on something the venue already owns, which is why every one of them can start as soon as the venue is assessed. The other two are at glencook.fit/programs/walk and glencook.fit/programs/indoor.
02 · POINTS OF DIFFERENCE

Music first, a full slot, one class, and a measured result

The class is built around the soundtrack, not decorated with it.

Nine tracks at 128 to 130 BPM, one per segment; changes on the chorus; the group moving as one to the beat. That is what people turn up for and what they bring a neighbour to, and it is why attendance is reported to you as the headline rather than buried under it. The tracks are beat-mixed fitness covers from Power Music, and the licence position is settled per pool, because the music is a feature of the product, not background.

One class, five dials. Not a beginners’ class and an advanced class.

Water scales in ways a chair or a bench cannot: depth, hand shape against drag, lever length, distance from the wall, tempo against the music. Every participant works the same track at their own five settings, so the person with two hands on the wall and the person travelling the width are in the same session, on the same song, with nothing to be seen in. Two half-filled classes become one full slot.

The wall is the equipment.

Heel raises, hip work, squats against buoyancy, push-ups and pulls, all at the edge of your pool. No lane ropes moved for storage, no floats, no kit left in your plant room.

Twelve weeks ends in a measurement, not a renewal conversation.

Attendance and retention per session and per block, and four functional tests on the deck at week 1 and week 12, reported to you in writing with the change and its direction. Not a grade, not a traffic light.

03 · EVIDENCE

What the program claims, and what backs each claim

Aquatic exercise in older adults is well supported, and every figure on this page carries its source. Where a figure has a limitation its own authors raise, a wide interval, a dose the program does not reach, it is written here rather than left for your clinical staff to find.

BalanceAquatic exercise improves balance test performance in older adults. Berg SMD 1.13 (0.25–2.00); chair stand also improved.Deng et al., European Review of Aging and Physical Activity, 2024

The line worth knowing

The outcome measures move; the fall rate has not been measured. Balance scores, chair stand and Timed Up and Go improve with aquatic exercise, and those are the tests this program runs. No adequately powered trial has measured whether that becomes fewer falls in water; the investigators running such a trial say so in their own protocol. So this program is not described as falls prevention, and no falls figure from the land literature is quoted for it. If your clinical staff check one thing on this page, it will be this, and it will check out.

Worth knowing when you compare providers

A provider who quotes falls-reduction percentages for a water class is quoting land trials. The pooled falls figures in the literature come from land-based balance programs and do not transfer to water, where buoyancy removes the challenge those programs are built on. This program quotes the aquatic literature for the aquatic class and stops where it stops.
04 · THE POOL FIT

Why this format suits an aquatic centre

The program was designed around a shallow end that is empty mid-morning, a wall that is already there, a population that does not use the pool at 6 am, and a kiosk. That describes most public pools on the Sunshine Coast.

Your off-peak hour

A standing weekly booking of up to 10 in a slot the lap swimmers have left. Attendance per session is counted and reported, so the value of the slot is a number, not an impression.

Your shallow end

Standing depth, floor visible, a wall with a graspable edge, steps with a rail. A roped-off width for the travelling rung. Nothing installed and nothing stored.

Your members who don’t swim

The people your lane program cannot reach: sore joints, replaced hips and knees, low confidence on land. Water removes the barriers that keep them off land programs (Bartels et al., Cochrane, 2016; Waller et al., Age and Ageing, 2016). No swimming required; nobody leaves the floor.

Your kiosk

Every session ends at the café where the pool has one. The social half is designed in, not incidental. It is what keeps a twelve-week program at twelve weeks, and your kiosk sees it too.

What you provide

The slot, the shallow end, a place for a speaker, your supervision arrangement, a noticeboard and a liaison contact. No staff time in the session beyond your own lifeguard policy, no capital cost.

Community, not clinical

This is a fitness class, not hydrotherapy, and it is not represented as hydrotherapy. It is delivered under a fitness professional's scope: screening, routing to GP or physiotherapist where a flag is raised, and nothing that diagnoses, treats or prescribes.
05 · PROGRAM CONTENT

Five blocks, nine tracks, five dials, twelve weeks

The structure of a session never changes across the block. The difficulty does, governed by a written progression model rather than instructor judgement on the day.

E · Entry · 4 minRoll and screening changes on the deck; in by the steps, one at a time, rail in hand.
W · Warm-up · 8 minSlow water walking along the wall and range work. Hand shape is taught unloaded here, before it carries anything.
A · Water walking · 8 minWidth walks and patterns to the track. The functional-mobility content and the social track, on fresh legs.
B · Wall work · 8 minHeel raise, hip work, knee raise and squat against buoyancy; push-up, pull and wall sit. The wall is the equipment.
S · Strength against drag · 8 minArms through the water on the drag dial; legs on the lever dial. Where the strength effect comes from.
C · Cool-down and supervised exit · 9 minTempo down, stretch in the water’s support, and a supervised exit one at a time. The highest-risk moment of the session, run as such.

The five dials

Progression is one continuous ladder, not lanes. Each participant sits on a rung of each dial, recorded by name. Anchor markers are shapes, ▮▮ ▮ ◻ ▷, so they read the same in print and to a colourblind reader.

D · DepthWhere the water line sits on the participant, standing tall on the pool floor.waist → navel → xiphoid
A · AnchorHow much of the wall the participant is using, and whether they stay by it.▮▮ wall, two hands → ▮ wall, one hand → ◻ off the wall → ▷ travelling
G · DragHand shape and surface area moved through the water. The load dial for the arms.sliced hand → open palm → cupped → equipment
L · LeverBent or straight limb; how much of the arc is used. The load dial for the legs.short → long → long, full arc
T · TempoMoves per beat against the track. The intensity dial: faster through water is heavier.half water tempo → water tempo → land tempo

The principle underneath

Work is added by drag, lever, tempo and distance from the wall, never by leaving the water's support. Depth is set per participant for their joints and moves alone. One dial advances in any week, only after two consecutive clean sessions, and the wall stays within reach at every rung including travelling. Intensity is set by perceived exertion, not heart rate (Andrade et al., Sports Medicine, 2022).
06 · DOSE

Where the dose actually comes from

The strength effect above was produced by programs running two to three sessions a week, and it peaked at 24 weeks (Wang et al., Frontiers in Public Health, 2025). A once-weekly twelve-week block sits under that dose. This page says so rather than implying one session a week delivers the meta-analysis result.

Once weekly is the entry offer

It fills a slot, it builds the group, and it is the frequency most operators can give a new booking. It is under the strength dose and is described that way.

Twice weekly is the dose

Where a second off-peak slot exists, a second session in the same week is the version that sits inside the evidence, and it is a second hour of occupancy for you.

Re-enrolment is the duration

The effect in the dose analysis kept rising to 24 weeks. A group that re-enrols for a second twelve-week block is closer to the literature than one that does not, and the second block has the harder rungs waiting for it.

There is no take-home program

There is no pool at home. Participants who use your pool in public hours between classes are doing the right thing, and that is more utilisation, not less.

The dose arithmetic, stated honestly

One 45-minute class contains about 16 minutes of wall work and strength against drag and about 8 minutes of water walking. That is one session a week where the pooled effect came from two or three. The class establishes the movements, the hand shapes and the habit of coming; it does not, on its own, reach the dose. This page will not tell you otherwise.

Attendance, the number the program plans around

No adherence figure specific to aquatic classes in this population was verified in the literature, so none is quoted. Instead it is measured: attendance per session, sessions per participant, retention at week 6 and week 12, and leavers by reason, reported to you in writing. That is the product's distinguishing claim, and it should be a measurement rather than an assertion.
07 · WHAT IS NOT CLAIMED

The limits, stated plainly

  • This is not falls prevention. Aquatic exercise improves balance test performance, and balance is a recognised risk factor. But no adequately powered randomised trial has measured whether water-based exercise reduces falls; the investigators running one say so in their own protocol (2020), and a 2023 review that pre-specified falls as an outcome found no trial had collected it (Melo et al., PLOS ONE, 2023). The outcome measures move; the fall rate has not been measured. Where falls reduction is the objective, the evidence points to land-based balance programs, and GlenCook.FIT runs two of those. This one is the access route for the people who cannot or will not do that work on land.
  • Not better than land-based exercise. The best age-matched review finds comparable effects on dynamic balance, with the point estimates numerically favouring land (Kim et al., BMC Geriatrics, 2020); the physical-function review finds at least as good (Waller et al., Age and Ageing, 2016). The claim is reach, not superiority.
  • Not bone. The aquatic bone-density evidence is against no exercise only, and it has never been tested against weight-bearing exercise (Schinzel et al., Frontiers in Physiology, 2023). Water is non-weight-bearing.
  • Not hydrotherapy, not clinical. Nothing in this program diagnoses, treats or rehabilitates. Conditions are flagged and routed to GP or physiotherapist clearance, including clearance to exercise immersed for cardiac and respiratory histories.
  • Not mental health. No systematic review of aquatic exercise and depression in older adults was located. The claim is left out.
  • Results are reported as change, not as clinically meaningful improvement. Minimal detectable change values for the deck tests in this population were not established for this program, so reports state the number and the direction of travel.
  • The evidence base is younger and more female than your members. Mean ages in the reviews sit in the mid-60s and the trials are mostly women. Neither point invalidates the findings; both are known before they are quoted to a board.
08 · MEASUREMENT

Four tests on the deck, twice, reported in writing

The 30-second chair stand and the Timed Up and Go are the instruments the aquatic meta-analyses use as outcomes, so the program measures the things the literature says should move. All four tests are performed on the deck, dry, before entry, because a land test performed in water is not the same test and has no norms. Same tester, same order, same time of day, same footwear, same walking aid.

30-second sit-to-stand

Lower-limb strength and chair-transfer mechanics

Scored against CDC STEADI age and sex norms for context. A participant who needs their arms is tested with arms, recorded as such, and reported as change only.

Source: CDC STEADI, 30-Second Chair Stand.

Timed Up and Go

Change in mobility across the block

Used as a change score only, never as a falls screen. A 2014 meta-analysis found pooled sensitivity of 0.31 at the 13.5-second threshold and concluded TUG should not be used in isolation to identify individuals at high risk of falls.

Source: Barry E et al. BMC Geriatrics, 2014.

4-Stage Balance Test

Static balance across a graded narrowing of stance

Reported as the stage reached, and nothing more. No falls-risk category is attached to it in this program.

Source: CDC STEADI, 4-Stage Balance Test.

4-metre gait speed

A single-number summary of mobility

Needs 8 metres of straight, dry concourse. Where the deck cannot provide it, the foyer is used or the test is recorded as not testable; the distance is never shortened and scaled. Reported as a graded value in metres per second, never as a pass or a category.

Source: Studenski S et al. JAMA, 2011.

Why the TUG caveat is on a sales page

Because your clinical staff will know it, and a provider who quotes TUG as a falls screen tells them everything they need to know about the rest of the proposal. The test is retained because it is a sound measure of change and because the aquatic literature reports it. It is not presented as something it is not.

Reporting format

Reports state the measured number and the direction of change. They do not assign grades, ratings or colour categories, they do not describe a change as clinically meaningful, and they never attach a falls-risk score to any result. A participant who moves backwards on two or more tests is flagged in writing for clinical review, not given a harder rung.
10 · DELIVERY AND COMPLIANCE

One instructor, from the deck, documented

Delivered by Glen Cook. There is no team and no subcontracting: the person in the specification is the person on the deck.

Delivery

Group capped at 10, instructed from the deck with the whole group and the steps in eyeline (AUSactive, Aqua Exercise Instructor Guidelines, 2022). Entry and exit by the steps, one at a time, rail in hand, with a seat on the deck. Standing up out of the water’s support is when a participant is most likely to feel faint (Pendergast et al., Comprehensive Physiology, 2015), so the exit is run as the highest-risk part of the session.

Pool requirements

Standing depth with the floor visible; steps with a rail; a wall with a graspable edge along the working length; a dry deck position with the group and the steps in view. A written pool assessment covering water, entry and exit, the wall, the deck, supervision, emergency arrangements and the music licence is completed on the assessment visit and supplied to you before the first paid session.

Set per pool, in writing, before the first session

  • Supervision. Whether a lifeguard is on duty during the class, and whether solo instruction from the deck is permitted, is set by your own policy and risk assessment. I work to what it specifies.
  • Water temperature. The program is written for 26–30 °C. Your pool’s displayed and measured temperature is recorded at the assessment and on every session record.
  • Music licence. Tracks are Power Music beat-mixed covers, which addresses the recording side. Whether your OneMusic Australia licence covers a contracted instructor’s classes is confirmed in writing. No answer, no class.

Screening, scope and incidents

APSS Stage 1 pre-exercise screening for every participant, no exceptions (APSS, 2nd edition, 2025), plus your conditions of entry. Cardiac and respiratory history, orthostatic hypotension, seizure history, joint replacement, osteoporosis, Parkinson’s, post-stroke, cognitive impairment, vestibular history, anticoagulant use, open wounds and infection are flagged and routed to GP or physiotherapist clearance. Emergency contacts on paper for every participant; your pool emergency procedure read and signed. Any slip on the steps, unintended submersion or dizziness on exit: the session stops for that participant, the incident is recorded the same day and supplied to you, and a GP letter is offered. Loss of consciousness, chest pain, new confusion or seizure: 000 first.

CREDENTIALS & INSURANCE

Credentials and cover

Certificates, insurance and screening documents are supplied with every proposal and are available on request. Aquatic instructing credential, and the insurer's confirmation that it meets their wording for deck instruction: in writing before any agreement is signed.

Book a pool assessment

A pool assessment takes about 30 minutes and settles whether this is viable, for you and for me: depth, entry and exit, the wall, the deck, your supervision policy, your licence position and your water temperature. You see the written assessment whether or not you proceed. If the pool does not work, that is a useful answer and it costs you nothing. Prefer email? Write to hello@glencook.fit or call 0488 883 408.
