Workout Intensity: How Hard Should You Go to Get Results?

Let’s be honest: some days you feel like Wonder Woman, other days you’re clinging to the coffee machine for dear life.

So the question is:

What is the right workout intensity for women over 40 to get stronger, fitter and more energised?

If you’re not gasping for air or drenched in sweat, was it even worth it?

And what happens when you’ve had a rough night, work’s been non-stop, and the idea of pushing to the limit feels like a hard no?

At Plan B Fitness, we work with women in Teddington, Twickenham, Goring and Taunton who are balancing careers, families, and busy social calendars. They don’t have time to waste, and they certainly don’t want workouts that leave them wiped out for days.

Here’s what we want you to know: Intensity matters, but it’s not about going harder. It’s about going smarter.

What Does Workout Intensity For Women Over 40 Really Mean?

In simple terms, intensity is how hard you’re working during a session. That might mean lifting heavier, doing more reps, cutting rest time, or moving faster.

But high intensity doesn’t automatically equal better results. And it definitely doesn’t mean doing brutal workouts every day.

Here’s a quick example:

  • 30 bodyweight squats in 10 minutes = low intensity
  • 30 squats in 30 seconds with weights on your back = high intensity

Both are valid. The key is choosing the right level of intensity for your body, your goals, and, let’s be honest, your week.

Why “Smash It Every Time” Doesn’t Work (Especially for Women in Midlife)

We get it. The fitness world is full of hype.

“Push harder.”

“No pain, no gain.”

“Train insane or remain the same.”

But here’s the truth: going full throttle all the time is a fast track to burnout, especially for women juggling work, family and hormonal changes.

What many people don’t realise is that too much intensity can:

  • Raise cortisol (your stress hormone)
  • Disrupt sleep and recovery
  • Trigger cravings and energy dips
  • Stall fat loss and muscle gain
  • Leave you feeling tired, moody, or injured

It’s not just about what your body can do, it’s about what your lifestyle can support.

The Plan B Fitness Approach to Intensity

At Plan B Fitness, we take a more intelligent route.

We don’t throw you into the deep end. We meet you exactly where you are, and then gradually help you build strength, energy, and confidence without sacrificing your wellbeing.

Let’s look at two local examples:

Laura, 52 – Twickenham

When Laura joined us, she was in perimenopause, sleeping poorly, and overwhelmed. We started her on moderate strength sessions twice a week and encouraged light walking on other days. Now, 8 months in, she’s lifting heavier than she ever thought possible, sleeping better, and says she finally feels like herself again.

Sam, 41 – Goring

Sam came from a background of intense online home workouts. She thought exhaustion meant progress. But she was stuck with low energy, high stress, and no results. We introduced structure, and focused on fueling and recovery, and helped her find balance. She’s dropped 2 dress sizes and now looks forward to training because it fits her life, not fights it.

This is what smarter intensity looks like. Just enough to get results. Not so much it breaks you.

Relative Intensity: Why Your Workout Shouldn’t Look Like Anyone Else’s

Intensity isn’t a one size fits all thing. What feels challenging for one person might be a warm-up for someone else.

A 30-minute power walk might be perfect for someone starting out. A fast-paced strength circuit might be ideal for someone with more training under their belt.

And it changes week to week based on:

  • Stress
  • Sleep
  • Hormones
  • Nutrition
  • Life stuff (you know, the real things that matter)

That’s why we adjust your workouts based on how you’re feeling, not just what’s on the plan.

Some days we’ll push. Some days we’ll pull back. The key is in the consistency.

So… How Hard Should You Go?

Here’s what we tell every woman who walks through our doors:

  1. Any movement is better than no movement.
    You’re not starting from scratch. You’re starting from experience.
  2. You don’t need to be flat on your back to make progress.
    You need the right mix of challenge and recovery.
  3. Your intensity should match your goals and your life.
    And that’s something a good coach can help with.

When you work with us, you’ll never have to guess how hard to push. We’ll guide you, adjust for your energy and goals, and make sure you’re progressing without hitting burnout.
