Problems with Many to Many Relationship

Hi, i have a many to many relationship. This raw sql show the desired result:

select player_id
FROM player_training
INNER JOIN players
ON players.id = player_training.player_id
WHERE training_id = 2

How can i get the same result with eloquent?

I have three tables:

• players
• trainings
• player_training

I need the data from a trainingday.
