  • 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.
  • It takes 72 hours for your body to start losing muscle mass after you stop working out. I don't believe that to be correct. Most good routines I've followed give that muscle group up to 6 days rest (work it 1x a week).
  • 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.
