Fitness does not need to practice every day, if it is simply to lose weight and strong body, should be a practice every other day the effect is better. If it is simply to train muscles and become a bodybuilder, 1 week should practice 5-6 days, leaving only 1-2 days to rest, which is more reasonable, muscles need to rest. Fitness also needs to supplement a lot of protein powder and other nutrition, not simply by exercise can make more muscle. Fitness needs to be carried out under the guidance of professionals, so as not to make the body’s ligaments, muscles too damaged, more scientific, more reasonable so that fat reduction, so that the muscles become strong, gradually become better. Personally, I thought fitness needs to be a persistent plan, not a three-day fishing trip, should be a long-term plan.
