30 Day Crunch Workout Challenge

Tone up your abs and core muscles with this simple 30 day crunch challenge workout. You start by completing 50 Sit Ups on Day 1, and slowly increase to a maximum of 250 by Day 30.

Crunches are exercises that require you to lie on your back, tighten your abdominal muscles and lift your head and shoulders upward. When performed properly, they can improve the strength of your abdominals and define your core muscles. As a core-training exercise, crunches help improve your balance by strengthening your abdominal muscles. Strong core muscles improve your posture, which helps you function efficiently in everyday life and in sporting events.

“It was a great challenge! My abs strengthened quite a bit. I fell behind for a few days but made it up and stayed on track afterwards. Loved it! :) Once we hit the 200s, it was tough to do back to back days of it.”
