Ab exercise videos operate on the same principles as any other muscle-working video: You need resistance training with enough weight to tire the muscles for the best exercise programs. Abs workouts move beyond endless crunches and sit ups with the addition of a few simple aids to increase the strain and instability that works core muscles. The best abs exercises are part of exercise programs working other muscle groups so you can work your major muscles while also tightening the abs. Core exercises are the foundation of all power lifts.
Ab exercise videos aren't much help for looking good on the beach if you don't work in some fat burning exercises. All the ab workouts in the world won't give you six pack abs if you don't peel away the fat hiding the abdominal muscles. But even the best ab exercises can't target where the fat will start dropping from, so you have to lose it all. Core exercises have to be part of a total body fitness exercise program for you to enjoy the fitness results you can show off.
The best ab exercise videos work in some simple pieces of equipment to jazz up core exercises. Ab workouts that add in an element of instability work the core muscles more thoroughly. Home exercise videos such as Tony Horton's P90X® include detailed instructions on how to use key pieces of gear to supercharge simple abs workouts. The best abs exercises are the ones you can only do a handful of times before reaching muscle failure.
Abs exercise videos need a healthy side helping of total body workouts to really be effective. Abs workouts can be found in surprising forms, such as shoulder presses or squats, once you realize that the key function of abdominals is stability and that anything that challenges that stability can become intense core exercises. If you want to know how to get 6 pack abs, learn to work on your shoulders, legs, back, and butt at the same time. Even cardio workouts can become part of your ab workouts.
