Please help: when I go to the gym, my trousers start to slip down, especially on the treadmill. This has happened my entire gym going life, from being (fairly) young and slight to much older and larger (and yes, I have bought new trousers to match my size). So please, wise ladies of Mumsnet, can I draw on your sartorial expertise and suggest solutions or alternatives. Shorts would not work, as I do not wish to show up the lovely ladies of love island (Haha). Sorry, but I am posting for traffic, my post pandemic size requires drastic measures and gym going is one of them.
