Chicken breast can be eaten 2 hours before fitness or 1-2 hours after fitness.
It's best not to eat immediately after fitness. Although chicken breast is rich in protein, it is difficult to absorb it quickly. Half an hour after fitness, you need to eat protein, such as protein powder and eggs. This will get twice the result with half the effort.
Don't eat before exercise 1 hour, so protein will be consumed during training. If you are losing weight, chicken breast is a good choice. If you want to gain muscle, you can choose high-calorie and high-protein meat like beef.
