Bad posture is caused by weak and/or tight muscles, especially in the core area, which I can imagine would be a problem if you're trying to move heavy objects around.wheelin&dealin said:I've got a better posture exercise. It's called lifting weights. Squats, deadlifts, cleans, bench presses will all strengthen muscles that will naturally put your body in a better postion. Therefore your posture is automatically better and you don't have to work on posing like Zoolander. But, cool tip none the less.
I've heard of guys injuring themselves - sometimes badly enough to have to quit doing squats, DL, etc.- from weightlifting without being in good enough shape for it.
The only way to fix tight muscles is by stretching. Your muscles have to be made stronger, I agree, but I have to think there's a safer way to do it for guys who are so out of shape that they should be glad they can move at all.
