"You need to lift heavy."

"Put down the pink dumbbells."

"Do 3 reps of 3 exercises, 3 times per week."

If you're a woman over 40 in perimenopause or menopause, you've heard that message everywhere. But if you're new to strength training, that advice can feel confusing at best and intimidating at worst.

Here's the thing: "lifting heavy" actually has two completely different meanings online. And if you don't separate them, you can easily end up trying to train in a way your body isn't ready for yet and then incorrectly assume strength training "isn't for you."

In this episode, I break down what "lifting heavy" actually means, what I want you doing right now, and what the long-term roadmap looks like if your goal is to truly lift heavier weights over time.

The first meaning: lifting heavy for you

This is the one I want almost every midlife woman to focus on first.

"Heavy for you" simply means you pick a weight that challenges your muscles. Your last one or two reps feel hard. You slow down. You have to concentrate. You're not using a weight that’s so light that you could keep going till the cows come home.

This matters because in midlife, you don't want to chase "the burn." You want to build muscle and increase your strength: results that support your health and aging well (while making you look and feel great in your body!)

When you train with weights that challenge you, you're sending your body the signal to build muscle and build strength. That muscle matters because it supports metabolic health and blood sugar control. Your muscle is your glucose sink.

So yes, I agree with the message: you should lift heavy for you.

I just want you to understand what type of "heavy" you're aiming for right now.

The second meaning: lifting heavy weights with low reps

This is the version people usually mean when they say things like "3 reps" or "lift REALLY heavy."

If you're doing only 3 reps, you must use a much heavier load than you'd use for 10–12 reps. That's the whole point.

I used a simple comparison in the episode: running as fast as you can for five feet is a totally different effort than running as fast as you can for a mile. Shorter efforts let you push harder. Same thing with weights.

This style of training can be useful.

It's also the one I don't want beginners rushing into.

Why I don't want beginners starting with "3 reps heavy"

Here's the part I don't think gets said enough online: heavy is a journey. It's not day one.

In your first year (and honestly, sometimes the first two), your body is learning. It’s learning movement patterns. It’s learning how to recruit muscles, how to stabilize, and how to do each lift with confidence and control. That takes time, especially when you're learning new exercises.

Plus, your muscles aren’t the only things that have gotten weaker: your tendons, ligaments and bones have gotten weaker too. And they don’t strengthen as quickly as your muscles do. For that reason, slow and steady progression is best.

And there's also a practical piece people skip: truly heavy lifting requires a more disciplined warm-up process. If your body is cold and you grab a very heavy weight, the chance of a strain goes way up. Beginners usually aren't training with that warm-up structure yet.

This is also why I push back when programs imply you'll be ready for very heavy, low-rep training after a short "beginner phase." In my experience, it takes months to build the base.

The roadmap to lifting heavy weights

If your long-term goal is to lift heavier weights in lower rep ranges, I love that goal. I just want you to earn it in the right order.

Start by building your base in a moderate rep range.

The 8–12 rep range is a smart place to work as a beginner. It's challenging enough to build muscle, but your early reps act like a built-in warm-up before you hit the hard reps near the end of the set.

That's why my Learn to Lift Program stays in 8–12 reps. Nobody starts with 3 reps of something heavy.

Then, over time, you gradually shorten the rep ranges.

Not on every exercise, and not all at once. You choose exercises that make sense for heavier training, and you use warm-up sets when loads get heavier.

So what should you do right now?

If you're newer to strength training, I want you focused on "heavy for you."

✅ Pick weights that challenge you

✅ Work mostly in 8–12 rep range

✅ Get close to failure while maintaining proper form

✅ Build consistency and confidence first

Then, when your technique is solid and your body feels ready, you can start experimenting with lower rep ranges on the right lifts. Remember those warm-up sets!

If you've been hearing "lift heavy" and feeling like you're failing because you're not doing 3-rep sets, I want you to relax a bit. You're not behind. You're building the base that will let you lift heavier down the road safely and effectively.

How to take the next step

If you want a plan that takes you from "I know I should lift" to "I actually lift, consistently, and I'm getting stronger":

  • Learn to Lift is my 10-week beginner program (home or gym, 2–4 days/week)

  • Monthly Membership is where you keep progressing through structured blocks so you're not guessing what to do next
