Depending on your preferred type of workout, you’re going to need different kinds of shorts. For example, if you like to run, you might want split shorts or some that are not as long, so the extra fabric doesn’t get caught up between your legs and slow you down.
If you’re going to the gym to lift weights, on the other hand, you’ll want shorts that are a little bit longer or ones that have a liner. That way you can keep things comfortable and classy when you lie down to bench press or do any leg raises on the mats.
We spoke with six personal trainers about the pairs of shorts they reach for every day. Each trainer looks for something slightly different — the right length, number of pockets, a soft feel that holds up after hundreds of washes. Here are the shorts they swear by.
Mike Aidala, the MAST Method

Ten Thousand Interval Short
“The simplicity and refined minimalist details are what I love the most,” says Mike Aidala, personal coach and founder of the MAST Method, says. “I used to be into more flashy gym wear, but now it’s all about not letting my workout clothes distract me from my actual workout.” Pick from a 7- or 9-inch inseam, liner or linerless and then six colors ranging from black to blue to grey. These sweat-wicking shorts move with you as you attempt that handstand for the fifteenth or fiftieth time.
