Best Workout Boxer Briefs for Men in 2026

Most boxer briefs quit on you mid-workout. They ride up under a squat, chafe by the second mile, lose their shape by lunch, and leave you adjusting through the rest of the day. The wrong pair turns a session into a constant fidget — which is exactly why the best workout boxer briefs are worth getting right.

The fix is a brief built for training first — a secure fit and honest support that lock in under the bar and hold through everything after. Below is the pair we'd reach for first — the AD Performance Brief — shown in all four colors so you can stock the whole gym drawer. Every color is in stock; tap Shop Now on any image to buy.

What makes the best workout boxer brief

The fit

Sits snug at the waist and stays put — no riding up the thigh.

The support

Holds everything in place through training, sitting, and long days.

The leg

A trim leg that won't ride up or chafe under shorts, joggers, or a squat.

The waistband

Lies flat without digging in, even after hours on your feet.

The day

Comfortable from a morning workout to a late dinner.

Here's the brief that checks every box — in all four colors.

AD Performance Brief

This is the workout boxer brief you reach for when you want to stop thinking about your underwear. The AD Performance Brief sits snug at the waist and keeps a trim leg that stays put through a lift, a run, or a long day on your feet — no riding up, no chafing, no mid-set adjusting. It gives you real support whether you're under the bar, on the treadmill, or out the door after, and it holds that secure fit from the first rep to the last meeting. Comfortable enough to forget you have it on, dependable enough to be your everyday default — and it comes in four colors so you can stock the whole drawer.

Black

The everyday default — disappears under anything in your closet and pairs with every color you own.

Navy

A quiet step off pure black that sits clean under most trousers and darker outfits.

Charcoal

A soft mid-grey neutral that pairs with greys and earth tones without going stark.

Stone

The warm-weather pick — light enough to vanish under summer chinos and lighter trousers.
