Resistance training has been shown to increase muscular strength. However, there is a difference in results between traditional low-intensity training (performing one exercise at a time with a typical 30-60 seconds rest) and HIRT protocols. A 2017 study compared two groups: individuals who followed HIRT-style workouts and individuals who followed traditional training. Results showed that both groups had the same muscle hypertrophy, but individuals in the HIRT group yielded greater overall muscular strength.
