elastic bands are made of latex, with a length of about 30 cm and differentiated by color in relation to their degree of stress (8 in total). As the length increases during stretching, the rubber offers increased resistance. This increase in resistance coincides with the end of the concentric phase of exercise, usually less demanding muscle tension for the individual, so we have a more constant and phases of relative rest. Its increased use is the training of endurance and muscle strength as well as being very suitable for toning, definition and muscle hypertrophy. The advantage of the weights is that they offer a more limited resistance to the latter, so there is a greater muscle control during exercise (one of the great advantages is that it is much better controlled eccentric phase of exercise), making this is more effective because it works more specifically (to improve the physical qualities faster) and to avoid injuries from the improper use of other muscle groups. is important to remember that training with elastic bands should be supervised by a qualified professional.
