Designed for unrestricted movement with a little rough-around-the-edges attitude, the Runyon Workout Muscle Tank is a unisex athletic tank designed for women who run, lift, hike, cycle, and train. The relaxed muscle tank silhouette combines roomy arm openings with Runyon's distinctive inside-out construction for an original workout shirt that looks as good outside the gym as it does during a training session.

Roomy Muscle Tank Design

Generous arm openings create the defining look and feel of the Workout Muscle Tank while providing plenty of room to move through the shoulders and upper body. The open design is especially comfortable for weightlifting, strength training, CrossFit, indoor cycling, running, hiking, yoga, and mobility workouts where freedom of movement matters.

Inside-Out Rough Edge Construction

The signature inside-out construction moves traditional seam details to the exterior, creating the distinctive unfinished aesthetic that separates this muscle tank from a traditional gym shirt. Exposed seams and rough-edge detailing give the tank a casual, slightly rebellious look inspired by cutting the sleeves off a favorite workout tee — only intentionally designed that way from the start.

Designed for Running + Lifting

The Workout Muscle Tank was created for athletes who don't limit themselves to one type of training. The roomy upper-body design works naturally through presses, pulls, rows, curls, and overhead movements while maintaining the relaxed feel needed for running, hiking, cycling, and outdoor workouts.

Its streamlined silhouette also makes it easy to transition beyond training. Pair it with running shorts for trail miles, workout shorts for the gym, or casual shorts for an everyday athletic look. The result is a versatile workout muscle tank for women that feels equally at home lifting weights, logging miles, or spending the day outdoors.

Designed with unisex sizing, the Workout Muscle Tank gives women a relaxed athletic fit with extra room through the arm openings and upper body. Designed, cut, and sewn in the USA, it reflects Runyon's approach to creating original athletic apparel for people who train, explore, and stay active in more than one way.
