I don?t know if this is a tip as much as a fix for us “executive” types?
I used to carry my executive bag w/computer in my left hand consistently for several months if not years. Eventually, I started noticing muscle imbalances in my left arm. It was getting bigger, and my left trap started rounding out larger than my right side. I weighed my bag and realized that it was around 25 LBS. It was a hard habit to break, but I switched to my right arm, and after about two years, I?m now seeing my right arm catching back up to my left arm.
Tip: If you carry a computer bag on a daily basis, be mindful of balancing your load.
