9.Overload Your Bag
Heavy weights can strain your back and tire out muscles that you need to support your spine. This can affect kids who lug many books. Your child’s backpack shouldn’t weigh more than 20% of their body weight. Large, padded, adjustable shoulder straps help spread the weight evenly. But only if you use both straps. Slinging your pack or heavy purse over only one shoulder can cause strain.
10.Ride the Wrong Bike
Or just a badly adjusted one. It’s bad for your back if you have to hunch over to grab your handlebars the way pro cyclists do. (They train hard to do it safely.) You also may have back pain if you’re too stretched out or cramped up on your bicycle. A physical therapist can help you find a bike that’s a good fit and suggest exercises to help if you have lower back pain.
