Some muscle groups received only six weekly sets.<\/p>\n<p>Dr. Mike Zourdos, professor at Florida Atlantic University\u2019s muscle growth lab, explains why more isn\u2019t always better.<\/p>\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>From sets 1 to five, you\u2019re getting a lot of growth. From 5 to 10, you\u2019re getting some. And then every time you add sets after that, we\u2019re not as confident that you\u2019re still getting more growth.<\/p>\n<\/blockquote>\n<h3 class=\"wp-block-heading\"><span id=\"Intensity_Matters_More_Than_Volume\">Intensity Matters More Than Volume<\/span><\/h3>\n<p>Dr. Zourdos\u2019s team discovered something more impactful than set count: proximity to failure.<\/p>\n<p>When lifters stopped sets eight reps short of failure\u2014where most gym-goers typically train\u2014muscles still grew.

Split your weekly volume across at least two training sessions per muscle group.
