Frequently Asked Questions: FAQ

frequently asked questions

What is semi-private training, and how is it different from regular group classes?

Semi-private training is a small group workout format, with a 5:1 client to trainer ratio or better. Unlike larger group sessions where the focus is on a generalized workout for everyone, semi-private training offers more individualized attention. Each session is customized to meet your personal fitness goals, whether you’re looking to build strength, lose weight, or improve mobility. This allows for more personalized coaching while still benefiting from the group atmosphere, creating a supportive and motivating environment.

Can I attend semi-private sessions if I’m new to working out?

Yes! Our semi-private training is perfect for individuals at any fitness level. Whether you’re a complete beginner or a seasoned athlete, we tailor each workout to meet your abilities and goals. Our trainers will provide clear instructions and ensure you’re using the correct form to avoid injury. We’re here to support you every step of the way, making sure you progress safely and effectively.

What if I have an injury or physical limitation?

We understand that injuries and physical limitations can be a concern when starting or continuing a fitness program. That’s why our certified personal trainers are trained to customize your workouts around any injuries or limitations you may have. We can modify exercises to avoid aggravating injuries while still allowing you to make progress and build strength. Whether it’s a knee issue, back pain, or any other condition, we’re here to help you train safely and effectively. Our goal is to help you achieve your fitness goals without risking injury.

How long will it take for me to build strength?

The time it takes to build strength varies from person to person and depends on factors such as your starting point, consistency, and the intensity of your workouts. In general, many of our clients start noticing improvements in strength within the first few weeks of training, especially with our customized approach. However, significant changes in muscle mass and overall strength usually take a few months of consistent effort. Remember, building strength is a long-term process, and the more committed you are to your training and nutrition, the more progress you'll see. Our expert trainers will guide you every step of the way to ensure you’re on track to meet your goals.

How long is each workout session?

Each workout session is 60 minutes long. We aim to have you in and out within that hour, making the most of your time. The session typically begins with a 10-minute warm-up to get your body ready for the workout. The main workout portion lasts between 40 to 50 minutes, depending on the focus for the day. Whether you're building strength or focusing on other aspects of fitness, we ensure you get a complete, effective workout within the time frame.

Can you help me with my nutrition?

Yes, absolutely! All of our trainers are certified nutritionists, and we believe that combining proper nutrition with fitness is the key to achieving incredible results. Our programs are designed not just to help you build strength, but also to support your nutritional needs every step of the way. With personalized coaching, ongoing accountability, and a tailored nutrition plan, we ensure that you're set up for success and that you stay on track to reach your fitness goals.
