Stretching: If you do work that might be hard on your back, take the time to develop a stretching routine. Take a one-minute stretch break every now and then to avoid that
Slow down: If you’re doing a lot of heavy, repetitive lifting, take it slow if you can. Allow yourself more recovery time between lifts as well. Don’t overdo it. Take frequent short breaks.
Get in shape: Strengthen your stomach muscles, lose a little weight, increase your flexibility.
Sleep on a firm mattress: Use the proper sleeping position
