Some of the things i eat (depending on what i am doing):
Oatmeal with peanut butter
I wake up at 05:50 when I want to go to the gym, and I don’t feel much like having breakfast at that point. My workout begins at 07:00 or 07:15 and I usually eat one or two bananas and/or a couple muesli bars on my commute.
But I often feel too tired, like depleted, while exercising, especially if doing weight lifting. I often feel very thirsty and like no amount of water will fix this.
When doing cardio, even hard workouts (eg 1 hour elliptical), I don’t miss my breakfast at all.
When running outdoors in the morning I feel like I perform much better with no breakfast at all.
If I would train in the evening, I like to eat after my workout. But thats my preverence. Besides, I like to train in the morning.
