I need advice on trainers! I've decided to join a gym after many years and do an intense body blast camp for 6 weeks! So now I'm stuck I dunno what sort of trainers to buy? Do I need special ones that cover all exercises & weights or will any old Nike Gym type ones do, obviously not the fashion ones. I don't want to pay 100s so a budget friendly option would be great, just in case I die 😂
