There is no conflict. Long distance running consumes more fat. When the muscle contracts with high intensity (overcoming heavy weight) or repeats with low intensity, the original muscle tissue (muscle fiber) is damaged. The process of repair is the process of growth. At the same time, it is very important to pay attention to two points: 1, and the strength must be adjusted and relaxed after training. 2. When practicing, the results of high-intensity and low-intensity repetition are different. Low intensity repetition (slow) may make muscle bulge more obvious, but it may not be easy to use. Please correct me in my humble opinion.
