MYTH #2: NO PAIN, NO GAIN
A better phrase is “No effort, no gain” because pain isn’t necessarily a good thing. However, discomfort can be. So how can you tell the difference between the two? Simple: If it feels like a troop of gorillas is tap dancing on your spine, it’s pain. If your muscles are burning on rep 15, it’s discomfort.
A general rule: If you’re in pain, stop doing whatever you’re doing immediately. If you’re experiencing discomfort because you muscles are actually working instead of couch surfing, strap one on and be a man, man.
