prices on 6 models Sit-ups
— an isolation exercise for the abdominal muscles, mainly the upper ones. Sit-ups with weights cause muscle growth, without weights — burning fat. In modern machines, different types of equipment can be provided for performing these exercises. Most often, this is an ordinary bench with footrests and additional weights. However, a special mechanism for using weights may also be provided — usually it is a swinging lever that must be pushed by the body during the exercise.
