How long does it take to lose mucle mass after I stop working out?

It takes 72 hours for your body to start losing muscle mass after you stop working out. Most good routines I’ve followed give that muscle group up to 6 days rest (work it 1x a week). Two weeks for the body to start lossing muscle mass according to Mike Mentzer. It varies from person to person. Some people might take 3 days, others two weeks. It also depends on a person’s diet.

In my opinion, when you train your muscles your body goes through a faze that is called hypertrophy, this is an increase in muscle size, and this happens when you train with weights, or even when you walk a long distance, an increase in muscle mass is called hypertrophy, hence hypertrophy training, now….. when you lose muscle mass, this is called atrophy, it is a faze that your body goes through once you become sedentry or idle or just stop working out, but here is the catch, atrophy starts almost immediately after a workout, and continues until you next train or do some form of hypertrophy training. this isn’t a negative thing if, so please don’t think you have to work out continuously just to keep the muscle mass you have gained, it is a slow process, but you will feel its effects within a few days of not doing any form of exercise or weight training, this is why it is good to have a continues routine in place, and also to mix up your training schedule, style, and weight level to “shock” your body and allow hypertrophy to continue, also REST is a vital component to keeping your muscles big and healthy so do allow time for this.
