If you're looking for a way to really transform your body in a short amount of time, an abs challenge is a good place to start. Building a strong midsection will help you get more out of every exercise you do, because your core is the source of your stability and power. What's more, toning your back and abdominals muscles (they're both part of your core!) will help prevent low back pain and improve your posture. Nice, right? I've designed this 30-day abs challenge to ensure you never get bored! ~ Berceste
