Key Moments
Key difference training women vs men: women want glute focus, men say yes to everything
The biggest training difference between men and women is goal specificity. Women typically prioritize glute development above all else, while men will take hypertrophy in any muscle group. This fundamentally changes program design.
"If you were like, hey, Andy, you mind if I slap a little muscle on your traps? You'd be like, I'll take it. I'd be stoned. Sure. Buys, tries? Sure. Pecs? Upper, lower? Yep. You can't name a muscle right now that I'm not going to say yes to. You can say yes to everything. We want to grow everything. And so therefore, when we do our leg days with squats and deadlifts and lunges, that tends to grow a lot of quad and adductor and glutes."
Why women train glutes 3x/week: glute specialization requires reducing other volume
Women training glutes 3 days per week is essentially a glute specialization program, which requires reducing quad, hamstring, and upper body volume to allow recovery. Building bigger quads without matching glute growth makes glutes look proportionally smaller.
"They don't train for maximum glute hypertrophy. If they did, they would have separate glute days. The women care about that."
Women recover faster from glute workouts and likely need more total volume than men
Women appear to recover faster from lower body training -- they can repeat intense glute workouts the next day while men need two days. Higher estrogen and type 1 fiber hypertrophy may explain it. Optimal weekly volume for women may be around 16 sets vs 12 for men per muscle group.
"These women can do these workouts. I tried to do one once, 2007. Tried to do what I give my girls. I was on the ground laying there for half an hour. I was like, is it possible to have a heart attack at 30, 31 or two or something? And I remember just sitting there like, wow, that made me gain respect for what I put them through. So yeah."
Tempo doesn't matter for hypertrophy: 2 to 15 seconds per rep yields the same growth
Research shows rep tempo between 2 and 15 seconds produces identical muscle growth. Slow eccentric tempos don't add hypertrophy benefit. A study on cheating vs strict form showed the same muscle growth, but strict form is safer with lighter loads.
"If they're doing like a two second up and four second down, that is the slowest hip thrust known to man. People, this is one of the most, the biggest things people are wrong about in the industry is that tempo matters so much for hypertrophy. It doesn't. Look at a lot of these bodybuilders are heaving away. They're using momentum. They're exploding because intuitively they know a lot of them were doing like length and partials to just doing bottom position stuff and"
Explosive hip thrusts build athletic power better than slow controlled reps
Prescribing the same tempo for all exercises ignores range of motion differences. Explosive concentric hip thrusts develop horizontal power for sprinting while causing less muscle damage than slow negatives. Concentric is king for athleticism.
"And they don't consider the range of motion. So how to tell me you don't know about weight training without telling me you don't know about weight training is mention that all exercises need the same tempo. What do people do with cab raise? What about shrugs? Am I supposed to do shrugs with two seconds up, four seconds down? No. Shrugs are one second. You don't need to..."
