Treading Water
Treading water keeps you upright at the surface using continuous kicks and underwater hand sweeps. It develops swimming endurance, coordination, and control while keeping your airway clear.
Higher injury risk. Read the safety notes before adding weight.
- Intermediate
- Higher injury risk
- Rest 45 sec
How to do it
- Hold the pool wall with one hand, your body upright and your feet off the bottom.
- Start small, continuous flutter kicks, moving your legs forward and backward alternately beneath you.
- Release your grip on the wall.
- Sweep your hands side to side just underwater, with your palms slightly angled to press water downward.
- Maintain the kicks and hand sweeps for the interval, keeping your mouth above the surface.
- Return to the wall to finish.
Form cues
- Keep your shoulders relaxed
- Breathe steadily
- Keep your knees soft
- Use loose wrists
Common mistakes
- Lifting your arms above waterKeep your arms submerged so your hands can provide support.
- Trying to lift your chest clearLet your chest stay submerged rather than spending energy pushing your torso higher.
- Frantic, oversized kicksReduce the size of your kicks to a steady rhythm that keeps you in place.
Safety
Fatigue or loss of coordination can let your airway slip underwater, creating a drowning risk. Deep water leaves no standing recovery if you lose control.
- Practice in a lifeguarded pool with direct supervision until you have reliable deep-water control.
- Stay within immediate reach of the wall while learning.
- End the interval before fatigue makes breathing or staying upright difficult.
- Grab support immediately if you experience cramping, dizziness, or distress.
If you cannot float or return to the wall independently, learn supported water skills with qualified swimming instruction before attempting unsupported treading.
