You can't eat too much before fitness, but you can't eat on an empty stomach. You can eat bananas and milk, and you can exercise for 40 minutes to an hour after meals. Moreover, diet is very important, muscles need nutrition to grow, and they should eat reasonably! Here are some suggestions for you. If you want to shape, you can't eat greasy things, and try to reduce the intake of animal oil and beer. My coach cooks without oil, but eats lean beef and chicken breast! The most important things are vegetables and fruits. Because you sweat a lot, you will lose a lot of vitamins and calcium, so I don't recommend you to use some supplements such as protein powder at the beginning.

1 Warm-up exercise lasts about 15 minutes, which can make your body sweat slightly.
