Friends, I have been training again with heavy weight (3-4-5) recently, but this repetition level, especially if the number of sets is high, tires the nervous system, my advice, do not do low repetitions for more than 2 weeks, maybe the injured person will not get injured in 6 weeks, but now he hit me on the collarbone, maybe you Although not now, it may recur in a much different and severe way in the future.
