Anthem Athletics Hyperflex Mens Gym Shorts - Stretch Performance

In this review the Anthem Athletics Hyperflex mens gym shorts stand out as a versatile training short built for mobility and secure storage. Designed for HIIT, cross-training and running, these shorts use a medium-weight polyester/spandex blend and flat-lock stitching to balance durability with stretch. The biggest reason to consider them is the combination of a true performance fabric and large angled zipper pockets that keep a phone secure during dynamic movement.

Key Features

• Stretch performance fabric: The polyester/spandex blend provides freedom of movement for squats, lunges and sprints without feeling restrictive.
• Selectable inseams: Available in 5 in, 7 in and 9 in lengths so you can pick how much quad coverage you want for running or lifting.
• Secure angled zipper pockets: Deep YKK zipper pockets keep phones and essentials secure and out of the way while training.
• Moisture-wicking construction: Medium weight fabric moves sweat away from the body and maintains coverage during intense sessions.
• Flat-lock stitching and drawstring waist: Seams lie flat to reduce chafe and the elastic waistband with drawstring keeps the fit stable through repetitions.

Who It's For

The Hyperflex shorts are best for men who do mixed-discipline training: people who split time between HIIT, CrossFit-style work, lifting and short runs will appreciate the balance of stretch and structure. Runners who prefer a bit more coverage can choose the 7 in or 9 in inseams, while those who want maximum quad mobility can go with the 5 in.

These shorts are not tailored for endurance marathon runners who favor ultralight minimal fabrics or for users wanting a loose, relaxed boxer-short fit; they lean toward a performance, slightly athletic cut. If you prefer a roomy, casual short for everyday wear, consider a different looser style.
