You Only Need 4 Sets Per Week To Build Muscle

Most of social media will tell you that building muscle takes hours in the gym every week. Fifteen, twenty sets per muscle. Five, six days a week. The peer-reviewed research says something very different — and once you see the numbers, you can't unsee them. In this video, I break down 15+ years of resistance training research to answer two questions everyone in the gym is actually asking: how much do I really need to do, and how hard do those sets need to be? No hype. No bro-science. Just what the evidence actually says — and exactly how to apply it in about 90 minutes a week. If you're busy, skeptical of fitness noise, and you just want to know what actually moves the needle, this one's for you. -------------------------------------------------------- Chapters: 0:00 – The lie you've been sold 1:43 – What the research actually says about volume 2:58 – The diminishing returns of more sets 5:58 – Why almost none of it works for most people 7:08 – The one variable that changes everything 8:25 – How hard is hard enough? 11:35 – Your complete program (6 movements, 90 min/week) 14:14 – The bottom line -------------------------------------------------------- The studies referenced in this video: Volume / Dose-Response https://pubmed.ncbi.nlm.nih.gov/41343... https://pubmed.ncbi.nlm.nih.gov/27433... https://pubmed.ncbi.nlm.nih.gov/20300...

I've been lifting for 15+ years, I compete as a natural, and I use an engineer's approach to cut through fitness noise: what actually works, how much it matters, and what you can skip. No hype, no shortcuts, no BS — just the evidence and how to use it. Connect: Instagram: @psmlifts TikTok: @psmlifts
