Care to share what's the best technique to tread water?
As far as I know, there's no such thing as the
best technique to thread water; there's only
one technique. It's keep your head above water with your body in vertical position and your limbs doing scaled down breaststrokes, scaled down just enough to keep your head above water.
There's another technique but it's not technically threading water. It's just floating and flowing with the water. Keep your face up above the water in a backstroke position without the strokes, just enough waddle to keep your body afloat and face above the water.
