30 Seconds Summary
Is your split jerk limited by upper body or lower body strength?

  • Recent research analyzed the connection between strict overhead press, squat strength, and split jerk 1RM in competitive weightlifters to determine predictors of split jerk performance.
  • A study including 33 weightlifters found strong correlations (r > 0.9) between individual strength in overhead press, squats, and their combined influence on predicting split jerk strength.
  • A supplementary tool has been developed, available via an online spreadsheet, where athletes can input their 1RM for squats, overhead press, and split jerk to understand their performance and identify limiting factors.
  • The spreadsheet calculates expected split jerk performance based on individual or combined strength data and helps identify whether the limiting factors are related to upper body (overhead press), lower body (squat), or other factors like speed, skill, and technique.
  • The tool provides a confidence rating on its predictions, helping athletes gauge how substantial the gap is between their predicted and actual split jerk performance.
  • This diagnostic tool, though insightful, isn't guaranteed to be 100% accurate, but it can effectively guide weightlifters to identify and focus on potential weakness areas in their training.

New research on training to failure

I’ve written and talked about training to failure many times before, but this new study by Carroll et al. (2018, 2019 - same study split into 2 publications) provides highly relevant new data. To sum up the previous research, training to failure hasn’t performed very well in the literature. It adds…

“Well, it works for him.”

Any time an impressive lifter or bodybuilder posts a certain feature of their approach to diet or training, be it a meal plan, a split routine, or a video of a certain way to perform an exercise, criticism is inevitable, especially from the fearless online community of anonymous posters. Just as pre…

Can you gain muscle and lose fat at the same time?

We live in sad times for bodybuilding. Although broscience is finally losing face, it’s being replaced by what I can only describe as bodybuilding nihilism (‘nothing-ism’). Nothing supposedly matters. Nutrient timing? Just eat when you feel like eating. Full-body or split training? Whichever you pre…
