You know the phrase, lift from the knees and not from the back. How about lifting from the arm muscles and not from the shoulder and elbow joints? A lot of times I see people in the gym holding heavy weights in their hands, not bending their elbows and allowing the weight to just hang from the joints in their shoulders. Then you can see the pull in their trapezius and the strain in their neck as they compensate by pitching their head forward. It is a common mistake the heavy lifters make when moving weight around and it is a incredibly damaging to the entire upper body. The next time you lift heavy think about it. Should you lift so heavy?
