I just got one of those armband things for xmas. Now I get to the gym today and my friend proceeds to tell me that they’re actually bad for your arm. They actually can cut off the oxygen flow/blood circulation to that arm since your lifting heavy stuff. This in turn causes the arm to get fatigued quicker than the other arm, possibly reducing growth.
One option would be to loosen it (obviously) but it just falls down to my forearm. Can anyone else relate to this problem? Is it even true? Should I just ditch the whole armband thing and just put it into my pocket?
