Gone are the days when heading to the gym meant reluctantly pulling on an old pair of Bermuda shorts and a baggy Oasis T-shirt. Workouts are hard and don’t need to be made any harder by sweat-drenched cotton tees weighing you down (if you are trying to increase the challenge, try a weighted vest instead).

Modern workout shirts are made from polyester, which is excellent at soaking up sweat and then helping it evaporate, a property improved further by proprietary sweat-wicking treatments. Often you’ll find a little elastane (usually Lycra) is mixed in for added stretch which improves the range of movement, allowing you to move freely, without rubbing or chafing as you work your way through sets.
