🔵 PHASE 3: PEAK — LET’S LEVEL UP 🔥
The Peak Phase is where athletic performance gets sharpened, speed gets tested, and your ability to perform under fatigue gets pushed to a whole new level.

Here’s what each session delivers over the next 4 weeks:

💥 Maximus & Redline
Aggressive work‑to‑rest ratios + sustained high‑speed output. These two build the skill of performing efficiently under deep fatigue.

⚡ Triple Threat
Repeat explosive efforts + athletic conditioning. Fast transitions, fast feet, fast power.

🏋️ Pegasus
Develops the ability to sustain repeat efforts after pre‑fatigue from bodyweight patterns. Elevated heart rate, elevated challenge.

🔩 Pinnacle
Targeted strength testing so you can express the strength you’ve built all Series long — with confidence and control.

🔥 Spartan
Movement efficiency, transition speed, and power endurance under pressure. This one sharpens your athletic edge.

🌏 Down Under
A brand‑new hybrid session giving you the choice to lean strength or cardio while still maintaining high‑intensity output.

Together, these workouts improve speed, power, recovery between high‑intensity efforts, and your ability to perform under fatigue — preparing you to move faster, maintain output longer, and train like an athlete.

💥Cardio & Hybrid Days Matter

Cardio and hybrid days matter — and they matter even more as we age.

Maintaining muscle mass is incredibly important, but so is keeping your heart and lungs strong. When you train both strength and cardio, you’re building a body that stays capable, energetic, and resilient for decades.

A healthy heart + lungs help you:
❤️ Lower your risk of heart disease
📉 Improve blood pressure
⚡ Increase daily energy
⏱ Recover faster
🚶‍♂️ Maintain mobility and independence later in life

The healthiest bodies aren’t built by only lifting weights or only doing cardio.
They’re built by doing both — consistently.

Strength builds the foundation.
Cardio and hybrid workouts keep the engine strong.

🔵 Show up for every part of your week. Your future self will thank you.

🌟 MEMBER SPOTLIGHT: 500 CLASSES! 🌟

Today we’re celebrating an incredible milestone—500 classes! 🎉💪

Kathy Bhat fitness journey started with a simple but life-changing conversation with her doctor. At 52, she decided it was time to make a change and took that first step into fitness. That decision led her to TNT CrossFit, and when those doors closed, she found a new home at F45.

“I was lost when TNT closed. The F45 family made me feel welcome—even when I was confused! 😂 Less confused now, and I appreciate the challenge each workout brings.”

That’s what F45 is all about. It’s not just the workouts—it’s the people who make you feel like you belong from day one.

When asked why she’d recommend F45, her answer says it all:

“There is something for everyone at every level of fitness. And it’s fun!”

Congratulations Kathy on 500 classes! Thank you for showing up, trusting the process, and being such an important part of our F45 family. Here’s to the next 500! ❤️🔥

🔥 WHY CARDIO & HYBRID DAYS MATTER 🔥
Your F45 schedule is designed with purpose. Strength days build the foundation, while cardio and hybrid days help maximize performance, health, and results.
💪 Strength Training Benefits: • Build and preserve lean muscle • Increase metabolism over time • Improve bone density • Build strength for everyday life
❤️ Cardio & Hybrid Training Benefits: • Burn more calories during workouts • Improve heart and lung health • Increase endurance and energy levels • Improve insulin sensitivity and blood sugar control • Support long-term fat loss
One of the biggest advantages of our cardio and hybrid workouts is HIIT (High-Intensity Interval Training).
🔥 HIIT creates the afterburn effect, known as Excess Post-Exercise Oxygen Consumption (EPOC). Even after your workout ends, your body continues working to recover, helping you burn additional calories for hours afterward.
The result? More efficient workouts, improved fitness, and long-term results.
Ready to get the most out of your training week? Don’t skip cardio and hybrid days! 👊
