One of the most popular Ab exercises - Sit-Ups.
Rather than perform hundreds of repetitions in order to reach failure, increase difficulty by simply performing the same exercise on an Ab/ Decline Bench. If you're performing at home (with no Ab Bench), give V-Sit-Ups a try to further difficulty.
Need something even harder to perform at home? Okay. Give my sample home abs workout a try instead...Tri-Set of Lying Hip Flexion, Sit-Ups, V-Sit-Ups. Aim for 20 repetitions of each. I'm warning you now - this is tough!
