Complex training (alternating heavy resistance exercises with sport-specific plyometric drills) and soccer-specific power actions are preferred over traditional resistance exercises due to superior ecological validity and transfer to performance.

Incorporate complex training methods where you alternate heavy resistance exercises (e.g., squats) with explosive, sport-specific movements (e.g., jumps, sprints) in the same session. This approach has better 'ecological value' for soccer players than doing traditional strength exercises alone.
