It's time for another workout challenge, and this one is all about the abs. Perfect for those new to strength training, it's short and sweet — all it takes is a few minutes each day for the next two weeks and you're sure to notice stronger and more defined abs. Instead of doing basic crunches, this challenge involves five crunch variations to target different areas of your midsection.
Here are instructions for the five different variations followed by a 14-day plan to get you all the way to 100. It's not advised to skip right to day 14 (if you want to be able to laugh the next day without rolling over in pain), so follow the plan and adjust it as needed according to your schedule and ability level.
