Ever notice that you feel the muscle better on your warm up sets than you do on your working sets? Isn’t it so true that the lighter weights often burn way more than the heavy ones? Why do you think that is?

Well, one of the main reasons is that you’re not focusing all your attention on stabilizing a weight and barely moving it from point A to point B, likely using every muscle in the general vicinity to get it to move and the range is smaller than it was with the lighter weight. The problem here is that the tension has shifted everywhere but the working muscle!

Your body adapts and starts using anything it can to keep itself safe. You can continue lifting heavy weights, all day long, but without optimal muscle building tension, don’t expect to see any improvement in your skinny arms and legs. If you can’t feel your muscles then you won’t be able to exhaust them enough to elicit the hormonal, metabolic and nervous system response for muscle growth.
