Gym leggings or shorts should fit snugly but not feel overly tight or restrictive. They should hug your body comfortably without digging into your waist or thighs. A good fit means the fabric moves with you without bunching, sagging, or sliding down during your workout. You should be able to move freely, squat, and stretch without feeling restricted. If you notice any discomfort, pinching, or see the waistband rolling down, the fit might be too tight and you should try a size up. Conversely, if they’re slipping down or feel loose, you might need a smaller size. The right fit provides both support and flexibility, allowing you to focus on your workout without distractions.
