I read multiple times that the body gets used to certain exercises and will adapt to them, so the training effect for doing the same exercise minimizes. And although two quite similar exercises will often train the same muscles, they use them in different ways.
At the moment I have basically two groups of exercises that I switch weekly. I do the first groups of exercises in one week and the next groups of exercises in the other week. There are some exercises I do in both weeks.
I wonder if it is a good approach to reduce adaption. Should I switch in another cycle; every exercise day, only every two weeks or even less?
