The Otis-up is a weighted exercise focusing on the abdominal muscles, as well as the shoulders to a lesser degree. It primarily targets the rectus abdominus or “six-pack” muscles, but also involves the obliques and deep core muscles. It is normally performed on a decline bench holding a weight plate, but can also be performed with a dumbbell, kettlebell, or other weight.


  1. Allows you to train in lower rep ranges when bodyweight decline sit-ups get easy
  2. Weighted ab training can help the core muscles grow and look more defined
  3. Also challenges the shoulders, serratus anterior, upper back, and hip flexors
