Water polo needs water you cannot stand in. Where to find it, what a club will ask of you, and why the eggbeater kick decides everything.

A pregnant can swim safely in most pools, but not every pool suits pregnancy. What to check for water temperature, entry steps, deck grip and lifeguard cover.

Most pool companies build pools you can stand in, not swim in. A coach’s checklist of questions on depth, length, entry, edges and supervision before you sign.

Fashion swimwear and chlorinated lap pools are a bad marriage. Why regular pool swimmers need a two-suit wardrobe — a beach suit and a training suit — and how to buy each without wasting money.
