Dehydration is a downer. Fortunately, you can prevent it, along with its nasty side effects, like muscle cramps, headaches and nausea. Get the upper hand by always keeping a bottle at hand. Cheers to the three below.

Gatorade Squeeze Botle
$9 per six-pack
gatorade.com
Good for: workouts that take place in a single location [e.g., in the weight room or on a field] Benefits: simple to squeeze; doesn’t leak
Field tester: “It was easy to squeeze [and it] holds a lot of liquid, so it’s great when training in places where you can’t always refill your bottle.”
 
 
 

Sigg
$25
mysigg.com
Good for: carrying around throughout the day or during a light jog
Benefits: fits in most cup-holders; eco-friendly, lightweight and durable; scent- and taste-neutral liner
Field tester: “My drink stayed chilled, and the bottle’s neck was easy to grip while I ran. I liked the orbit-like bottle top, which seals off leaks with a twist.”
 
 
 

Shaker Pro 40
$12-17
4sportlife.com
Good for: post-workout, to jumpstart the recovery process
Benefits: holds 40 grams of conventional protein powder; shaker design crushes powder clumps to eliminate clotting for a smooth consistency every time
Field tester: “I wouldn’t recommend it as a straight water bottle, but the Pro Shaker 40 is sturdy and it did a good job of mixing my shakes so there were no clumps.”
