The full golf swing (backswing and follow-through) rotates the spine with a lot of force and little control
Lumbar spine muscles strain to help provide force for the golf swing
Disc and facet joint loading increases to help provide force for the golf swing
Bending over to pick up the golf bag and carrying it can strain muscles
Learn proper form and posture for playing golf, including a smooth, rhythmic swing in good balance
Choose a golf bag with a built in stand and dual straps
When picking up the golf ball, bend at the knees or get a device for your putter that lets you retrieve the golf ball from the hole without bending over
Consider hiring a golf professional experienced at teaching golfers with bad backs who can explain postures and techniques that reduce back strain and prevent back pain
