Ab machines vary in function, cost, and results. Some are bulky and expensive for gym use, while others are small and affordable for home use. Sit-up benches, abdominal balls, and tongue twisters are effective but can cause back discomfort if used incorrectly.
There are countless ab machines to help a person strengthen and tone the abdominal muscles that surround the stomach. These machines can vary significantly in function and results, not to mention cost. Some ab machines are designed to be used exclusively in the gym, as they tend to be quite bulky, heavy, and expensive, while others are designed to be used at home. They are designed to be small and compact, as well as lightweight and inexpensive. Simpler equipment such as exercise balls and pull-up bars can also be used to strengthen and tone your stomach muscles.
Anyone who visits the gym is likely to come across fairly simple ab machines known as sit-up benches. These benches are usually situated on a slope, and the user will lie face down on the bench. His feet will be secured in cradles or around a padded bar, allowing him to do bench squats. The incline is usually adjustable: the flatter the bench, the easier the squats, and the steeper the bench, the more difficult the squats. These ab machines are very effective, but using them can be hard on the back if the person’s form is not correct.
Abdominal balls are large exercise balls that are flexible and inflatable. These abdominal machines can be used for a variety of different exercises that can target the abdominal muscles or other muscles in the body. The ball is designed to support the weight of the body, and a user can perform exercises while sitting on the ball, lying on it, or supporting only the upper body, while the lower body must be supported. Such ab machines are sometimes used in conjunction with free weights so that the user can enhance the workout with higher resistance to the weight.
Tongue twisters are ab machines that force the user to crunch and twist at the same time, which strengthens not only the abdominal muscles in the front of the stomach, but those on the sides of the stomach as well. The design of such machines can vary significantly, but the general purpose is to cause a twisting motion while maintaining body weight. The downside to such machines is the stress that can be placed on the spine; People with lower back problems should generally avoid such machines, as they can lead to slipped discs or other types of back discomfort.
