From King Pro - Advantages
Ab machines are nothing new; They have been available to the public for decades. Some are simple ideas and others push the boundaries of technology to help you achieve rock-hard abs and that ever-coveted six-pack. The truth is, you can perform most ab exercises without the help of equipment with some of the same results, but every now and then a machine like the Ab King Pro comes along that offers a little more exercise.
motivation
Most people avoid abdominal training for reasons of motivation. Really, who can blame you? The idea of lying on the floor to do painful crunches and sit-ups is hardly motivating. This is an area where a machine like Ab King Pro can help. First, you have a nice comfortable platform from which to work your abs.
Freedom of movement
The real area where these machines excel is in giving you a greater range of motion. Instead of the paltry 90 degrees, using rockers or traditional crunch methods, you get a machine like the Ab King Pro that offers a 200 degree range of motion that better stretches and trains the upper abs, lower abs, and obliques. Another thing these machines offer is custom resistance levels. Once you feel comfortable and no longer feel the burning, you can increase the resistance.
Conclusion
Can you tone and tighten your abdominal muscles without the use of equipment like ab king pro? Yes, but how much strain will you put on your neck and lower back? If you're looking for a great way to tone and tone your abs, this and many other similar devices can make the process easier, more comfortable, and ultimately more effective.
