When working the abdominal muscles, a crunch type exercise combined with a leg lift or knee tuck movement puts focus on the core and lower abdominal muscles, according to WorkoutBOX. Because of this, a workout containing exercises for both areas is best. WorkoutBOX also recommends four sets of 30 to 40 seconds of exercise per set at a frequency of once or twice per week for a beginner workout.
Beginner and advanced workouts and lists of exercises are featured on exercise websites such as Muscle & and Strength, which features three simple abdominal workouts with recommended sets and reps complete with click-on links to videos showing each movement performed. In addition, an arsenal of 10 abdominal exercises, with a performance explanation of each, is available on the same page of the Muscle & Strength website.
Aside from prepared workouts, BodyBuilding.com offers a list of abdominal exercises with a video and photo guide showing either a male or female athlete performing each movement. It includes options for body only or equipment required, type of body mechanics used, force required (push or pull) and experience level. Fitness enthusiasts at any level can develop their own programs using this guide of movements. According to Muscle & Strength, a sound plan of attack for strengthening the abdominal area to gain stability and balance also provides aid when working other body parts.
