Anthem Athletics Hyperflex Workout Shorts Men 9 in Inseam - Knee

Our review of the Anthem Athletics Hyperflex Workout Shorts Men 9 in inseam finds these are built for men who want a comfortable, stretchy short that performs across gym, running and lifting sessions. The single biggest reason to buy is the combination of stretch performance fabric and an angled zipper phone pocket that keeps essentials secure without restricting movement. These shorts aim for a modern athletic fit and full range of American sizing, and in this review they deliver dependable mobility and a no-nonsense feature set for everyday training.

Key Features

• Performance fabric: Polyester and spandex blend provides stretch and mobility for squats, sprints and dynamic gym work without feeling restrictive.
• Secure zipper pocket: An angled zipper phone pocket keeps a phone or small items secure while running or during high-intensity workouts.
• Elastic waistband with drawstring: Adjustable waist ensures a snug fit during lifting sets and prevents the shorts from sliding down under load.
• Flat-lock stitching: Reinforced seams reduce chafing and improve durability through repeated machine washing and heavy use.
• Modern athletic fit: The 9 in inseam typically falls at the knee for a balanced length that suits lifting, cardio and casual wear.

Who It's For

These shorts are well suited to men who train regularly and want a versatile pair that handles running, gym sessions and daily wear. The 9 in inseam provides knee coverage that many athletes prefer for lifting and moderate running, while the stretch fabric supports a full range of motion.

Those who prefer very short running shorts or a baggier, loose fit should look elsewhere, and if you need a different length the brand offers 5 in and 7 in inseam options in separate listings. People who prioritize natural fibers may also want to consider blends containing cotton instead of full performance polyester.

Pros & Cons
