ok so what do you actually eat before a workout

Right so I've been trying to get back into going to the gym before my placement days and honestly the pre-workout snack thing is doing my head in. Like I don't want to eat a full meal and feel sick on the treadmill but I also can't train on nothing, I've tried that and it's grim. At the minute I'm doing a banana with a spoonful of peanut butter, which sounds dead basic but it genuinely keeps me going for the whole session. Sometimes I'll blend a quick smoothie if I've got 10 mins — oat milk, frozen mango, a bit of matcha powder, that's it. Tbh I think the matcha just wakes me up more than anything, I'm not gonna claim it's doing something mad, it just means I don't feel half asleep on the gym floor at 7am. The thing I can't figure out is timing. I've seen people say eat 30 minutes before, some say an hour, some say 2 hours and I'm like... I do not have 2 hours in the morning, be serious. I usually just eat about 20-25 mins before and it seems fine? But ngl I don't actually know if I'm doing this right. If anyone's got a proper routine that works for them I'd deffo try it cos I'm just winging it rn.
