I saw someone mention in the wrist strap thread that they liked these straps for rowing and it seems like they would be really easy to use for DB shrugs as well.
edit: had white box so it should work now, whether they are old school or normal they should wrap like in the vid anyways.
Doesn’t matter which way your grip is. The strap wraps around the bar and back into the palm of your hand. Wrap it the other way and it’s not doing anything.
