STRAIGHT-LEG CRUNCHES

Exercise Instructions:

  1. Lay on the floor and place your heels on a Swiss ball.
  2. Either keep your legs straight, or place a slight bend at the knee if it’s more comfortable.
  3. Crunch up by squeezing your abs HARD. Add a pause at the top position for an even better contraction.
  4. Start breathing out just before you start the rep. When you get to the top of the rep, you’ll get a much better abs contraction!

Muscles Worked:

Abs.
