Of course! People assume that due to the lightweight and flimsy appearance of resistance bands, free weights are better. However, studies have shown that muscle activity and peak load during elastic-resistance exercise is similar to free-weight resistance exercise. This means that when comparing the same exercise performed with an elastic resistance device or with free weights, the amount of muscle fibers activated is similar and the amount of force provided by the muscle fibers is similar.
Studies on elastic resistance training have also shown that programs using elastic tubing, elastic bands and similar devices increase muscle strength and muscle size and decrease body fat in a similar manner to free-weight training programs
