At Fierce45, we talk a lot about resistance — and for good reason. Those heavier springs and slow, controlled movements aren’t there to make class harder “just because.” They’re intentionally designed to help you build strength, increase lean muscle, improve bone health, and create long-term physical resilience.
Science consistently shows that resistance training is one of the most effective forms of exercise for improving overall health and muscle function — and training with meaningful resistance matters.
Resistance Training Does More Than Build Muscle
According to research published in the Current Sports Medicine Reports, resistance training can improve:
- Lean muscle mass
- Resting metabolic rate
- Bone density
- Insulin sensitivity
- Cardiovascular health
- Functional movement and balance
- Confidence and overall quality of life
The study found that just 10 weeks of resistance training increased lean body mass while also improving metabolism and reducing body fat. Researchers also noted that strength training helps combat the natural loss of muscle mass that occurs with aging.
At Fierce45, our resistance-based programming is built to challenge muscles through time under tension, slow eccentric movement, and progressive overload — all key drivers of muscular adaptation.
Why “Heavy” Resistance Matters
There’s a common misconception that Pilates should always feel light. While lighter resistance has its place, research shows that heavier resistance training is especially effective for improving strength and preserving muscle function over time.
Studies on resistance training in older adults found significant improvements in muscle strength and muscle size, even in populations over age 75.
That matters because strength is directly connected to:
- Injury prevention
- Bone health
- Joint stability
- Posture
- Longevity
- Everyday movement quality
At Fierce45, increasing resistance appropriately helps create the mechanical tension muscles need to adapt and grow stronger. That’s why your coach may encourage you to add more spring tension or challenge yourself with slower movement patterns instead of racing through reps.
Strength Without High Impact
One of the biggest benefits of the FierceFormer is that it allows for heavy resistance training in a low-impact environment.
Traditional heavy lifting can sometimes place excessive stress on joints when performed improperly. Our machine-based resistance system allows members to safely challenge muscles while maintaining control, alignment, and stability.
This combination of:
- Heavy resistance
- Slow tempo
- Constant tension
- Controlled movement
creates an incredibly effective strength-building workout without the pounding impact of many traditional fitness modalities.
Muscle Is About More Than Aesthetics
Building muscle isn’t just about appearance. Muscle tissue plays a major role in metabolic health, movement efficiency, and healthy aging.
Research shows resistance training can:
- Improve glucose control
- Support healthy cholesterol levels
- Increase bone mineral density
- Enhance mobility and independence later in life
In other words: strength training is one of the best investments you can make in your future self.
The Fierce45 Difference
At Fierce45, we combine:
- Progressive resistance
- Functional movement
- Core-driven stability
- Time under tension
- Low-impact training
to create workouts that are challenging, sustainable, and rooted in science.
So the next time your coach tells you to “go heavier,” know there’s a reason behind it. Those shakes, slow pulses, and heavy springs are helping you build strength that extends far beyond the studio.
Your future self will thank you.
