For years, the fitness industry taught us that there were specific rep ranges for specific goals.
Lift heavy for strength. Do 8–12 reps for muscle growth. Do 20 or more reps for endurance.
While there’s some truth to that, the latest research tells us the story is much bigger than that.
Here’s what we know today: your muscles don’t count reps. They respond to challenge.
Studies now show that muscle growth can happen across a wide range of repetitions—from as low as 5 reps to as high as 30 reps or more—as long as you’re working hard enough and getting close to your limit.
The key isn’t finding the “perfect” rep range. It’s creating enough tension, enough volume, and enough effort for your body to adapt.
This is exactly why we train the way we do at Integrity Fitness.
Our workouts combine strength training with strategic circuits, supersets, and timed intervals. You’ll often work for 30 to 45 seconds at a time, moving through exercises that target multiple muscle groups while keeping your heart rate elevated.
To some people, it looks different from traditional bodybuilding.
To us, it’s the perfect balance.
Our goal isn’t just to help you build muscle. We want to improve your cardiovascular fitness, increase bone density, boost insulin sensitivity, support healthy aging, and help you feel stronger in everyday life.
Most importantly, we want to do it in a way that fits into your busy schedule.
Here’s what the science says: muscle growth happens when you challenge your muscles enough that they have no choice but to adapt.
That doesn’t mean every set has to end with you collapsing on the floor.
In fact, newer research shows that you don’t need to train to complete failure on every exercise to build muscle effectively.
But here’s where coaching experience matters.
After working with thousands of women over the last three decades, I’ve learned that most people stop long before their muscles are truly challenged.
Many clients think they’re finished when they still have five or six good reps left.
That’s why we coach intensity so closely.
Sometimes we push you outside your comfort zone—not because we’re trying to exhaust you, but because we want to teach you what real effort feels like.
Learning the difference between discomfort and true muscular fatigue is one of the most important skills you can develop.
When you discover you’re stronger than you thought, everything changes.
Our circuits are designed to create the three key ingredients for results:
- Mechanical tension: challenging your muscles with resistance.
- Metabolic stress: creating the “burn” that comes from working hard.
- Training volume: accumulating enough quality work over time.
By combining these elements, we’re able to help you build lean muscle, reduce body fat, and improve your fitness—all in a single workout.
And no, we’re not doing “cardio with weights.”
We’re doing purposeful strength training in a format that keeps you engaged, efficient, and progressing.
The beauty of our approach is that it meets you where you are.
Whether you’re new to strength training, returning after an injury, navigating menopause, or looking to take your fitness to the next level, we can adjust the resistance, pace, and intensity to match your goals.
At Integrity Fitness, we’re not chasing soreness.
We’re not chasing exhaustion.
We’re chasing progress.
Because the best workout isn’t the one that leaves you destroyed.
It’s the one that challenges you, helps you recover, and keeps you coming back stronger.
That’s how real transformation happens.
