Tempo deadlifts are a great way to work on form and technique and they can also help you overcome sticking points. The eccentric pause not only can improve overall strength, but also promotes hypertrophy.
In this video, I have a 3 sec concentric tempo (may have cheated as this is my last set) using a lighter load (205lbs) with a 2 sec eccentric pause at the knees.
Add this accessory movement using a moderate rep range of 6-10. Remember the slower you go, the less load you use.
See where I'm going with this? Pauses can be an effective way to help you build strength and blow past your sticking points. Try Eccentric Pauses with these other lifts as well:
Pausing creates quite a burn but it will be well worth it.
