Do glute activation exercises actually work? Is the 5:2 diet worse for muscle retention than a continuous calorie deficit? Does vitamin D supplementation protect you against injury? Can blood flow restriction training help you gain muscle just as effectively as traditional training? I’m going to give you the TLDR for the latest studies on these topics. 

This podcast is another installment in my Research Roundup series of episodes, where I give you concise and practical takeaways from studies that I think are interesting and that can help us gain muscle and strength faster, lose fat faster, perform better athletically, feel better, live longer, or get and stay healthier. 

There is a ton of scientific research that gets published every year, and even if you narrow your focus to fitness research, it would still take several lifetimes to unravel the hairball of studies on nutrition, training, supplementation, and related fields. 

That’s why my team and I put a lot of time into reviewing, dissecting, and describing scientific studies in articles, podcasts, and books. 

In today’s episode, I’m tackling studies on whether glute “activation” exercises boost glute growth, how effective the 5:2 diet is for preserving muscle while you diet, whether vitamin D can actually help prevent injury, and how well blood flow restriction training works for building muscle. Press play if you want to learn the answers to those questions.
