If you have nagging injuries or low energy, don’t take a super-hard workout. Back off, go lighter, do less, or rest completely. Don’t struggle with poundages which are beyond you to handle at your current strength level.
Beware of following a professional’s workout, or training so hard that you can’t recover or, even worse, you injure yourself. Common sense is essential for longevity and success in bodybuilding, so use your head and train with appropriate effort, not a killing effort, for what you are trying to.
