What foods do you eat before and after workouts?

I typically have a breakfast of honey/cinnamon oatmeal, greek yogurt, dark chocolate, and an ounce of some sort of nut. Then I'll workout 3 hours later.

20 mins before a workout, I'll have some pre workout or coffee. The caffeine helps.

After the workout, I make sure to down a protein shake within the 30-60 min anabolic window, assuming it exists. I make sure I have that, at least, to give my body the resources it needs to get started on repair immediately. Ideally some kind of quality protein, eggs, tuna, chicken, etc, with some fruits/veggirs and rice/bread/quinoa.

A banana is definitely too little. You need more than that. You won't really have the energy to workout, probably. Might be worth trying though. You may be able to get a 10-15 min ab workout in.

I usually just drink water or have like cheese or fruit...

I skip the workout and go straight for the food.

It really depends on when I'm working out. Tonight was late so I had dinner before. I should eat something nutritious after, but I'm lazy so I had a couple of biscuits, a few squares of chocolate and I'll have some almonds now
