Quick deadlift training tip...
Do you recall the first time using an actual deadlift bar? The knurling, the diameter, and the whip of the bar made the pull almost seem easier.
When doing your speed, max effort, or percentage pulls consider using a stiff bar for these 2 reasons...
1️⃣Grip. A typical stiff bar has a less aggressive knurling, and is wider in diameter.
2️⃣It has little to no give. This teaches the lifter to take the slack not only out of the bar, but the body as well.
Try using nothing but a stiff bar for 3 weeks for all your pulls. You’ll be surprised when you go back to an actual deadlift bar how much more locked in it is.
