Dogmama, I've been told to never do Romanian deadlifts again...which is sad because I REALLY like how they make me feel - but both doctor and trainer think it puts too much stress on my neck.
You're supposed to grip the weight with your hands, not your teeth!
I guess the looking-up position would be hard on the neck vertebrae. Does that include squats & deadlifts?
To train a dog, you must be more interesting than dirt.
