At the beginning of fitness, some people's weight rises instead of falling, which is because the weight of muscles has increased. A person who lacks exercise has a small proportion of muscle fiber utilization, and the water content of muscle is lower than that of people who exercise regularly. After starting fitness, the utilization rate of muscle fiber is improved, and more water is brought into the muscle, so the weight is increased. This is actually a benign phenomenon, and the body is already changing in a good direction. Please don't worry about the weight figures!
