Building endurance is very important, and it requires a lot of hard and consistent training. It takes persistence. Look at it this way: your fuel tank needs to be big, but it also needs to be full.

During pre-season, exercise builds strength, but you also need good sleep, a healthy diet and intense preparation. Know your limits. Throttle your burn to last the full 90 minutes plus overtime if needed. Be clever too; learn to recover during the game. Use corner and free kicks to relax and catch your breath. Stretching also is very important after training and games to stay flexible. You’re strong and energetic, so keep going!
