In addition to the comparison test winners of the abdominal trainers and the simple products, there are various other alternatives that are advertised on the Internet and on TV. However, this muscle training is never as easy as the advertising claims. Ultimately, increased effort is required to stimulate the muscles in a way that encourages their growth. Strength training for the abdominal muscles can also be carried out without a device, even if normal sit-ups or crunches are by no means as effective as the same exercises on the abdominal trainer. The suspension trainers are an interesting concept that is becoming more and more popular. This is a construction made of tapes and fasteners that is fixed to the wall. The exercising person hangs his or her body into this suspension trainer and tenses the muscles in order to perform certain movements. The high body tension also stresses the abdominal muscles, even if these are less targeted than with the abdominal trainers. That is why the suspension trainers are also called full-body training devices. Other devices also work through vibrating force, but they don’t seem to be as mature as experience reports show. The weight benches and gymnastics equipment, which can be found in fitness studios but can also be used at home, are considered reliable if not as effective. There are corresponding exercises for targeted training of the abdominal muscles. Large-format equipment such as cross trainers also have a positive effect on the overall constitution and thus also on the slim figure, but they only train the abdominal muscles to a small extent.
