I often hear people say things like:
“Why does my back feel tight after class?”
“That felt harder than it should have.”
And sometimes, I already know why.
I just watched them in the water.
In my water exercise classes, I often see bodies getting moved around by the water the entire time. Not struggling with the workout exactly — but bobbing and drifting like a boat pushed by choppy waves.
That kind of movement can look active. But it’s not the same as being stable.
And that’s where the core comes in.
The core’s primary job is to keep you steady so the rest of the body can move efficiently. The pool is one of the best places to feel this because the water gives your body something to respond to right away.
Watch a busy pool class and you’ll often see it: bodies getting pushed around by the water, working hard just to stay upright.
When that happens, people aren’t really stabilizing. They’re being moved by the water instead of controlling it.
Learning to stay steady in moving water is one of the simplest and most effective ways to build core strength in the pool.
Next time you’re in the pool, try this.
Ask a friend to jog nearby to create some turbulence in the water. Your goal is simple: stay in place.
Can you feel the difference? This wider base and gentle pressure into the floor helps activate the glutes and core, creating a stronger base of support.
If you have small hand buoys, you can explore this further.
Hold them lightly out to your sides and, while keeping them at the surface, gently press down. This should feel easy — nothing forceful — just enough to feel the water pushing back.
Can you feel the difference? Your abdominals respond without you needing to think about tightening anything. The water is lifting up as your hands press down, and your body begins to stabilize between those opposing forces.
That’s your core doing what it’s designed to do.
From here, experiment with small changes:
Each small adjustment gives your body a new situation to respond to.
Instead of forcing control, your body begins to find it.
This is the kind of strength that shows up in real life:
It’s your body knowing how to respond without overthinking it.
Small hand buoys are a great tool for exploring this feeling. They create gentle resistance that helps activate the core while improving balance and control in the water.
As pool season approaches, they’re a simple piece of equipment worth adding to your swim bag.
Next time you’re in the pool, don’t worry about doing more.
Just stand, let the water move, and notice how your body responds.
Because sometimes the strongest thing you can do is learn how to stay still.
