Build the strength and energy your full life requires.
GBSC helps busy Seacoast adults train consistently in coach-led 45-minute classes—without needing to get fit first or force life to revolve around the gym.

Support that fits the life you have.
Most GBSC members are not trying to make fitness their whole life. They are professionals, parents, caregivers, and active adults who want training to make the rest of life work better.
We help you build your capacity so fitness fits your life.
- You want reliable strength and energy
- Your schedule changes from week to week
- You are returning after time away
- You need options for aches or limitations
- You want coaching without intimidation
One conversation. A clear recommendation.
Tell Eric what you want.
A short message is all it takes to start the conversation. Then we’ll take time to understand your history, goals, and what you need from a gym.
Talk about what matters to you.
Your complimentary Capacity Introduction gives us time to hear your history, goals, and concerns. Together, we explore a suitable starting point and what a realistic first week could look like. There is no workout during this conversation and no obligation to join.
Get an honest recommendation.
After hearing what matters to you, Eric will explain the options and help you decide whether GBSC fits. Most new group members begin with the $99, 30-day coached-class experience. View ongoing class rates.
Coaching that meets you where you are.
Momentum
For newer members, returning members, and anyone rebuilding confidence.
Performance
For days and seasons when you are ready to push strength and conditioning.
Engine Builder
For building aerobic capacity or training intelligently in a demanding season.
These are options within coached group training—not rankings. Your coach helps you select the appropriate challenge each day. Semi-private coaching offers more individualized programming; Eric can help you compare the options.
Support for your goals and your starting point
“Any physical challenges are met with positive support and workout adaptation.”
“They know each of us individually and are tuned in to what we need to meet our goals.”
Coaching that fits real life
“I have found that I can attend any class and I am supported with whatever my needs and my goals are.”
“We're both shift workers so we enjoy the variety of options available to members depending on their needs.”
Tell us what you’d like help with, and we’ll talk through a starting point that fits your life.
What you may be wondering.
Do I need to be in shape before I start?
No. Your starting point is adapted to your current readiness. You will not be expected to keep up with an experienced member.
Is this personal training?
We offer coached group classes and semi-private coaching with more individualized programming. Eric will listen to your history, goals, and preferences to help you explore which option fits.
What happens after I text?
Eric replies personally. If a conversation would help, you can choose a time for a complimentary 30-minute Capacity Introduction. Nothing is booked automatically.
Can I look around before contacting you?
Yes. Take the free one-minute Capacity Snapshot, review ongoing class rates, or view the class schedule. The Snapshot gives you a useful action without requiring contact details.
