New training frequency study: 5x beats 2x

  • Training muscles 5 times a week results in greater muscle growth compared to once or twice a week, as demonstrated by a study by Zaroni et al. (2018) involving resistance-trained men.
  • Both training groups performed the same exercises, sets, intensity, and had equivalent macronutrient intakes; however, full-body workouts led to more significant muscle thickness increases.
  • While many studies equate volume in training frequency research, real-life situations often result in higher total workloads with more frequent training due to unequal distribution of volume across workouts.
  • High frequency training is suggested to improve total volume load without increasing overall training fatigue, possibly lowering RPE (perceived exertion) and reducing DOMS (muscle soreness).
  • Frequent training might boost testosterone production and improve recovery, making it more sustainable and potentially leading to superior muscle gains.
  • Another theory suggests that highly trained individuals inherently benefit more from higher frequencies, indicating a tailored approach based on training status might be optimal.
  • The practical implication is that higher training frequencies should be considered for maximum muscle growth, as they enable increased volume and are supported by various studies.

New training frequency study: 3x vs. 6x

The Norwegian Frequency Project is a once-secret-now-famous study in which the Norwegian Powerlifting team participated to study the ideal training frequency of each muscle group. They found that splitting the same program up into 6 instead of 3 full-body workouts led to better strength development…

Bro splits optimal after all?

Since the Norwegian Frequency Project shocked the fitness community by finding greater strength development and muscle growth when training each muscle 6x compared to 3x per week, research on training frequency has boomed. I recently reviewed 2 new studies on training frequency and now we have anoth…

How many times per week should a muscle be trained to maximize muscle hypertrophy? New meta-analysis review

Training frequency is a controversial topic. Several studies find benefits of training a muscle more times per week, yet others many find it doesn’t matter. Which studies are right? One way to answer this question is by conducting a meta-analysis to get a sort of ‘weighted average’ of the whole lite…
