The novice has just started to practice dumbbells, and his arm hurts. It hurts when it is straightened. Why? Can we keep practicing? Or do you want to wait until it hurts?
There is no doubt that LZ wants a strong body, but it must be scientifically and reasonably trained, combining aerobic and anaerobic. Aerobics must be practiced every day, but strength training is not. It is best to practice every other day to give our muscles enough rest time, because the recovery time of muscles is 48 -72 hours. As for muscle soreness, it is normal. Remember to give your muscles a full massage after exercise (which is also helpful for muscle growth). I hope my answer is helpful to you. If you don't understand, you can add it! ! !
