A complex is when you sequence several exercises together into one set. Here you're going to do three variations of the front delt raise:

  1. Chest supported front raise (thumbs up)
  2. Incline front raise
  3. Seated front raise

Do as many reps as you can in each position. When you can't get another quality rep in one position, move to the next with no rest.
