No. Rare exceptions for injuries, even small exist. Certain lifts, deadlift, straps are fine and only cause a change in the rotation of the bar and provide nothing in terms of weight (obviously). Look it up if interested, DL straps. e; Not phoneposting anymore so I can explain. Think about Deadlift and how the bar is held. Both hands overhand grop (knuckled pointing away from body, forward), with the fingers wrapped around the bar. What this does is cause the bar to follow the path of least resistance which will cause the bar to rotate backward, toward the body, the legs. How deadlift wraps solve this is by having the anchor strap that wraps around the bar wrap in the opposite direction. This causes the bar to rotate forward, away from the body where to get out of the finger grip it rotates backward. These two rotational forces cancel each other out completely meaning the only force the grip experiences is the vertical pull of gravity. That's easy to hold rather than the rotation moving down the fingers and away from the hand.
