Go with shorts for HIIT, running, and hot gyms; choose joggers for lifting, warm-ups, or cooler days. Check inseam options (like 7" or 9") and look for stretch and secure pockets; our guide to picking the perfect men’s workout shorts can help.

Aim for an athletic fit that moves with you—snug at the shoulders/chest with breathable, quick‑dry fabric to manage sweat; REP’s Sigmatech shirts are designed for range of motion without cling. See key tips in our [gym T‑shirt buying guide](.

Use the size chart on each product page and compare to your measurements; choose true‑to‑size for a performance fit or size up for a more relaxed feel. For shorts, consider both waist fit and preferred inseam length.

Men’s Apollo joggers are cut for a straighter hip and rise, while women’s Vellus joggers use a higher rise and more room through the hips and thighs; both offer a tapered leg and stretchy, gym‑ready comfort. REP designs each fit to support training without restricting movement.
