Why do we feel the burn when using lighter weights, but not when using heavy weights?
In: Biology
Imagine filling a jar with rocks
If you use small rocks imagine how close you can get that jar to being truly full
If you use big rocks imagine how much space is still left in the jar when you can’t get another rock in
The burn is a build up of lactic acid. When you lift heavy weights, you fatigue faster than it can build up. It’ll catch up with you tomorrow.
