When aiming for hypertrophy, the rep ranges generally max out around 30 reps per set. Going beyond this range may not offer significant additional benefits.
While unilateral exercises like split squats can be beneficial in some cases for addressing muscle imbalances and preventing injury, they may not be necessary for most individuals as muscle imbalances are not always a concern.
If you get sick while on a cut, considering going back to maintenance to allow your body to mount an effective immune response. Chronic underfeeding may hinder immune response, potentially impacting muscle loss versus fat loss during illness.
Taking a break between a bulk and cut to solidify new muscle gains is a speculative topic. Some believe that unilateral exercises like split squats and single leg RDLs can mitigate injury risk and muscle imbalances. However, the necessity of focusing on muscle imbalances is debated, and unilateral exercises may be beneficial for specific cases or preferences, but not a default requirement for most programs.
Training studies have shown positive effects with a variety of rep ranges and loads, indicating independent benefits regardless of the model. Studies like the daily undulating periodization, both weekly and daily, have shown successful outcomes across different rep ranges. This suggests the importance of not confining training to specific rep ranges like 6 to 12 or 8 to 12, highlighting the potential benefits of varied training approaches.
Research on energy expenditure suggests a physiological limit of around 2.5 times the basal metabolic rate for sustainable daily energy expenditure. Studies by Jara Areta focus on low energy availability rather than deficits, emphasizing the concept of functional versus non-functional low energy availability. The distinction between these states acknowledges that the human body can adapt to periods of low energy availability without significant negative impacts, highlighting the nuanced effects of energy balance on performance and health.
In this episode of MASS Office Hours Live, Dr. Eric Trexler and Dr. Eric Helms dive into a comprehensive discussion on the topic of mini cuts, exploring their definition, common justifications for their use, and the hosts' perspectives on their potential benefits and drawbacks. The conversation then shifts to answering a variety of listener questions from the live chat, covering nutrition-related topics such as blood sugar management in healthy individuals, the necessity of a "maintenance" phase between bulking and cutting, saturated fat intake recommendations for high-calorie diets, fiber intake guidelines, and strategies for troubleshooting gastrointestinal issues related to specific foods. The hosts also address training-related questions, including the role of unilateral exercises in preventing muscle imbalances and injuries, optimal rep ranges for specific adaptations, high-frequency training for smaller muscle groups, and the challenge of distinguishing between diet fatigue and pushing beyond one's lower intervention point during a cutting phase. Trexler and Helms round out the episode by discussing the concept of energy compensation in the context of high-energy expenditure sports, touching on research related to metabolic ceilings and the limits of sustainable energy expenditure, as well as the notion of low energy availability in athletes.
