Chuck V's Secret.
We do good mornings on a regular basis. Here are some pointers of why and how we do things:
-We use the Bully Cambered Bar as our main bar. This is due to the placing on the weight in relation to the lifter's center of mass as well as it's ease on the shoulders.
-When doing them concentrically, 90% of the time we'll do it out of chain (pictured above), as it allows for a more manipulative ROM.
-The Safety Bar is our #2 choice followed by the Bow Bar, again for the ease of the shoulders.
-Front bands whether out the Monolift or power rack (pictured above) is very common as it teaches the lifter to 'pull back' rather than 'pull up'.
