Strength and Conditioning That Leaves You Feeling Good

This 30-minute strength and SIT workout is one of my absolute favourite workouts I’ve ever filmed. And if you know me, you know exactly why. It fuses the two things I love most. Strength and conditioning together in one session, done in a way that genuinely makes you feel amazing afterwards.

That’s what a strength and SIT workout for women over 40 is all about. Not burning yourself out. Not spending an hour on the treadmill. Just smart, targeted strength work followed by short, powerful bursts of conditioning that spike your heart rate and then let you fully recover before going again.

You’ll finish this one feeling energised. Strong. Like you gave it everything and you still have something left.

That’s the sweet spot. And that’s exactly what this workout delivers.

✔️ Build lean muscle with targeted strength clusters

✔️ Burn fat with short, powerful SIT bursts

Workout Overview

Why This Strength and SIT Format Works So Well for Women Over 40

Strength Clusters That Build Real Muscle

Each block opens with a strength cluster — three exercises targeting the same muscle group, done back to back for two rounds. You’re keeping those muscles under continuous load across multiple movement patterns. That’s real, quality volume in a short amount of time.

SIT Finishers That Actually Do Something

SIT stands for Sprint Interval Training. 20 seconds of everything you have. 40 seconds to fully recover. Two rounds. That full recovery period is the key difference between SIT and traditional HIIT, and it’s what makes this format so effective and so kind to your body at the same time.

Because you recover fully between rounds, you can actually go all out. And that’s where the results come from.

A Progressive Build That Protects Your Body

The SIT finishers in this workout are deliberately programmed to escalate in intensity as you go. Running Man in Block 1. Frogger in Block 2. Burpee to close it out.

That progression is intentional. By the time you hit the hardest movements your joints are warm, your body is moving well, and you’re mentally and physically ready to give it everything. Building through a workout like this means you’re never shocking a cold body, and at our age, that matters.

Recovery That’s Built Into the Design

For women in perimenopause, or anyone over 40 feeling the effects of hormonal change on their energy levels, this format is a game changer. The conditioning work is short and sharp. The recovery is real and generous. Your nervous system gets a genuine stimulus without being pushed into a state it struggles to come back from.

This is the kind of workout that works with your body, not against it.

Trainer Tips

✔️ On the SIT finishers — go all out. 20 seconds of genuine maximum effort. That’s what creates the conditioning effect.

✔️ Use every second of the 40-second recovery. Don’t rush ahead. Full recovery means full effort on the next round.

✔️ For the strength clusters, choose weights that make the final few reps genuinely challenging while keeping your form clean.

✔️ Notice how the SIT finishers get harder as the workout progresses — trust the build. Your body is ready for it by the time you get there.

✔️ Core finisher: if two full rounds feels like too much to start, one round is absolutely fine. Build up over time.

Frequently Asked Questions

Is this strength and SIT workout suitable for perimenopause?

Yes — and it’s one of the formats I’d most recommend for women in perimenopause. The short SIT bursts create a real conditioning stimulus without the sustained effort that can spike cortisol and leave you depleted. The longer recovery periods mean your body actually gets to rest between rounds. You’ll finish feeling energised rather than exhausted.

What’s the difference between SIT and HIIT?

SIT (Sprint Interval Training) uses shorter work intervals with longer, full recovery periods — 20 seconds on, 40 seconds off. HIIT typically uses shorter rest that doesn’t allow full recovery. With SIT you can genuinely go all out because you actually recover between rounds. The result is a bigger training stimulus with less total fatigue on your body.

Why do the SIT finishers get harder as the workout goes on?

This is intentional programming. Starting with Running Man and building through Frogger to Burpee means your joints are warm, your body is moving well and you’re ready — both mentally and physically — to give the hardest exercises your full effort. It’s a smarter and safer way to train than opening cold with your most demanding movements.

What weights should I use?

I used 4kg, 8kg and 15kg dumbbells. Choose weights where the final few reps of each strength exercise feel genuinely challenging but your form stays clean throughout. You’ll likely need lighter weights for overhead and accessory movements and heavier for lower body work.

Can beginners do this workout?

Yes, with modifications. Use lighter weights, reduce the intensity on the SIT finishers, and take extra rest between blocks if needed. The format is consistent throughout so it’s easy to follow once you’re in it.

How many calories does it burn?

Approximately 263 calories. This will vary based on body size, fitness level and how hard you push on the SIT finishers — which is where a lot of the calorie burn happens.

How often should I do this workout?

Once or twice a week works well alongside other training. It pairs beautifully with pure strength sessions on other days.

Do I need a gym?

No! Dumbbells and a small amount of space. Some of the SIT finishers like the Frogger and Burpee need a bit of room, but nothing that can’t be done in a lounge room.
