Water exercise: Use your noodle

Foam noodle (less than $10): Some ideas: Sit on it and work the upper body; place it along your back with arms outstretched to work the legs and abs; place it in front and rest your arms on it while working legs; wrap it around your waist; or straddle it.

Buoys (about $22 to $30 per pair): For a biceps curl, for example, hold the buoy in one hand, arm bent, with the buoy just above the water. Pull it down, keeping the elbow steady, and let it up slowly, fighting the urge to allow the buoyancy to carry it up. Or, hold the buoys out in front of your chest, arms straight, and push down toward your thighs, engaging the core.

Webbed gloves (about $15 to $30 per pair): The spaces in between the fingers are webbed, offering more drag when hands move through the water. That makes muscles work harder, increasing cardiovascular function.

Kickboard or paddle board (about $8 to $20): Grab the board with hands outstretched, or hug it to your chest and kick. Rotating the body from side to side engages the core.
