Can you help please? I've just started going down the gym this month and I've dug out what I think is appropriate kit, however it's probably been about 15 years ago since I've worn this sort of stuff, and it's all a bit nipped , I think I need to buy some new kit. The main thing of concern is... what do you wear below... I've been wearing some Adidas shorts that I suspect are actually swimming trunks. They have a sort of white mesh liner, are they swimming trunks? I've not worn anything underneath these - and they do chafe [-]a bit[/-] a lot. Should I buy something like football shorts? Do you normally wear undies under your shorts at the gym? I'm just a bit embarrassed to ask whilst I'm there, silly I know.
