30 Seconds Summary
Optimal program design 2.0

  • Broscience often leads to misconceptions in training, relying heavily on the subjective 'feel' of exercises like muscle pump and soreness, which don't accurately indicate muscle growth.
  • Many traditional training beliefs – such as the necessity of low rest periods and training muscles once per week – have been debunked by scientific studies showing no significant benefits for maximizing muscle growth.
  • Resting for longer periods between sets (up to 3 minutes) can lead to greater muscle growth compared to shorter rest periods, which mostly increase metabolic stress without positively impacting growth.
  • Training frequency should ideally be more than once per week for each muscle group as muscle protein synthesis post-exercise typically doesn't extend beyond 72 hours.
  • The traditional 'hypertrophy range' of 6-12 reps is not the only effective method for muscle growth; a variety of rep ranges can be beneficial, with both heavier and lighter weights proving effective depending on overall training volume and intensity.
  • Training to failure isn't necessary for maximum muscle growth, and often, performing sets to volitional interruption where one stops when feeling adequately challenged is equally effective.
  • Overall, workout effectiveness is more about total training volume and less about specific set and rep schemes, emphasizing the need for a well-rounded approach to optimize muscle growth over rigid, traditional methods.

Your optimal training frequency for the glutes: part II

The following article on glute training is written by Stijn van Willigen. Stijn now works for Bayesian Bodybuilding full-time. While this isn’t exactly Menno’s approach to glute training, it’s very much based on the Bayesian Bodybuilding principles of optimal program design. The article is aimed at…

What you should know about each muscle group

In this interview, Bill Wong AKA Dr. Swole asked me what you need to know to train each muscle group optimally. We go into optimal training program design with a lot of practical tips in terms of setting rep targets, exercise technique and exercise selection.

Don’t know which way to take your training? Evan Shy breaks down the complexities of programming to help you create a program that is optimal for you

Is there a maximum productive training volume per session?

Training volume and frequency are currently hotly debated. For good reason, as these are fundamentally important considerations for the design of a training program. Over the last year, several studies have reported surprising and seemingly conflicting results. One study says higher training frequen…
