Your Pool Wall Is Training Equipment

Ask most instructors how they add variety to a deep-water class and the answer usually involves equipment. Noodles, dumbbells, gloves, belts, boards. All of it useful.

The aspect of the pool that is almost never considered is the wall.

Deep Water Versus Shallow Water

In shallow water, participants still have contact with the pool floor. They can push off it, land on it, brace against it and use it to change direction. The floor provides a stable force they can use to drive movement.

In deep water, the body is suspended, buoyancy takes the load, and every movement meets resistance in every direction. That is exactly why deep water is such a good training environment. Participants can travel, rotate, change planes and work hard with very little joint loading.

It also means there is nothing solid to push against. Force has to be generated against water alone. Participants have to work hard to produce a fast, powerful, explosive movement; however, when they incorporate the pool wall into the movement, it provides the same stable surface they have in shallow water, allowing for different force production.

What a Fixed Point Gives You

Once the wall becomes part of the workout, consider the following four things.

Force production. A wall gives participants something to push off. Feet make contact, legs extend quickly, and the body travels. That is a genuinely explosive effort, and it is very difficult to create in deep water any other way.

Anchored strength work. With the hands holding position at the edge, the trunk and legs can work against the water while the upper body stabilises. Participants can put their effort into the movement rather than into staying afloat.

An alignment reference. A fixed surface gives participants immediate feedback about where their body is. Hips under ribs, shoulders down, neutral spine. Much easier to feel with a reference point than in open water.

Structure. Intervals need a start and a finish time. The wall gives participants a clear point to work from and return to, so work periods stay honest and recovery is genuinely recovery.

If your deep-water classes have started to feel a little same-same, this is where I would look first. Maria Teresa Stone is teaching exactly this at Aqua Immersion on 13 September.

Familiar Moves With a Twist

The best programming ideas rarely come from inventing new exercises. They come from asking a better question about the moves your participants already know.

Include the wall with a familiar move and the demand becomes completely different. Participants recognise the exercise, so you spend less time explaining and more time coaching, and they still get the satisfaction of something that feels new.

This is also what makes class design sustainable for you. You do not need an endless catalogue of exercises. You just need to explore how to change a familiar shallow water move so that it includes the wall.

Watching those combinations happen in the water is what Maria will be sharing at the Aqua Immersion 2026 Virtual Conference

Why an Interval Format Works So Well Here

An interval is a finite block of time, and that is exactly what an unfamiliar exercise needs.

Give participants a set work period and they have long enough to learn the movement, repeat it until it feels comfortable, and then add power to it once they have it. Then it comes down to what you put in each block. Timed cardio bursts, explosive wall push-offs, wall-supported strength work and athletic deep-water movement all ask for something different, so intensity keeps climbing while participants stay motivated and moving with purpose. No equipment required for any of it.

The creative combinations, and the coaching moments inside them, are what turn that structure into a class.

Come and see the full format on 13 September.

The Wall Gives Participants Something to Push Against

This is the part that matters most. A fixed surface means participants can create force, and creating force is what makes the effort in deep water real.

It also gives you something specific to coach. How much pressure through the hands? Where are the shoulders sitting? Are the ribs stacked over the hips, or has the lower back taken over? How hard should that push-off actually be, and what should it feel like when it is right?

Learn the Format at Aqua Immersion 2026

Deep End: Wall-Powered Intervals with Maria Teresa Stone is one of five sessions at the Aqua Immersion Virtual Conference on Sunday 13 September 2026.

Maria Teresa brings over 28 years in the industry to this session. She has trained thousands of instructors across the Australasia Pacific region, presents at international conventions, was inducted into the Fitness Australia Roll of Honour in 2016, and is a co-founder of My Group Move.

In this session she takes you through a complete deep-water interval format built on timed cardio bursts, explosive wall push-offs, wall-supported strength work and athletic deep-water movement. You will finish with new interval ideas, practical wall combinations and a class format you can use in your next deep-water session, with no equipment required.

The day also covers power training in the water, music that lifts a class, brain training layered onto real physical work, and movement prep to look after your own body. 6 AusActive CPDs, 8.5 REPs NZ CPDs and 30 FitRec points are on offer, and lifetime access to the recordings means the sessions stay with you.

Your deep-water classes do not need more equipment. They need you to use what is already there.
