Our new cycle begins TODAY💪
Over the last 6 weeks, we focused on building muscle through hypertrophy. Now it’s time to put that work to use.
For the next 6 weeks, we’re shifting into Strength: lower reps, heavier loads, and a focus on turning the muscle you’ve built into measurable performance.
🔔 Starting Monday, our new Strength cycle begins!
Over the next six weeks, our focus shifts from Hypertrophy to Strength.
New challenges. Same commitment to helping you get stronger every time you walk through our doors.
Let’s get to work! 💪
There’s a reason we train in cycles.
Every cycle is built by our coaching committee with a clear purpose. 🏆🙌
Each week builds on the last and every workout has an intention. This means your progress at Flagship wont’t be left to chance, and that progress is only a matter of time.💪✅
Think you need to “get in shape” before joining a gym?
That’s exactly what we’re here for. 🏆
Our coaches adjust movements to your experience, ability, and goals, so you can build confidence one workout at a time. 🤝
