Eccentric training has gained a lot of attention over the past few years. The benefits of eccentric training have always been clear; what has been difficult is finding ways to practically implement it. On this week’s podcast James de Lacey joins us to discuss some easy ways you can implement eccentric training into your program, ideas on flywheel training, preparing for combat sports, concussions, and more.

  • 0:00 – Introduction.
  • 3:15 – What James is up to now.
  • 5:00 – The benefits of eccentric training: “There are many benefits to eccentric training: it has a low metabolic cost, increases stiffness, high speed power, fascicle length, length-tension relationship, and much more.”
  • 8:00 – Eccentric for explosiveness and fast eccentrics: “With concentric training higher forces means lower velocity. But eccentrics can flip that: you can have high force and high velocity.”
  • 10:00 – Practical tips to implement eccentric overload and eccentric training.
  • 12:30 – Eccentrics in training for Olympic weightlifting.
  • 14:45 – Nick Garcia and ideas on tempo variations.
  • 16:00 – Flywheel tricks for eccentric overload.
  • 21:45 – Motorized eccentric overload.
  • 23:15 – Hip thrusts.
  • 24:45 – Olympic lifts and replacing exercises: “Can you imagine doing eccentric overload training only for the whole year? The stimulus has to be fun too. You need variation. Part of the reason I like Olympic lifts, even if the benefits are replicable, is that there is a coordinative skill element. That makes it a fun challenge.”
