Choosing the right class size is one of the most important decisions you can make when starting a strength training journey in Denver. The number of people in a room directly impacts the amount of coaching attention you receive, the level of accountability you feel, and the overall cost of your membership. At Colfax Strong Strength & Conditioning, we offer a spectrum of group sizes designed to meet you exactly where you are in your fitness journey. Whether you prefer the energy of a large group or the precision of one-on-one coaching, there is a format that fits your goals and schedule.

1. One-on-One Personal Training

Maximum individual attention and customized programming.
One-on-one personal training is a training format where a single coach works exclusively with one client for the entire session. This is the most intensive level of coaching available, allowing for real-time form correction and a program that evolves strictly based on your individual progress. It is ideal for beginners who need to learn foundational movements safely or for athletes targeting specific performance goals. At Colfax Strong, our personal training sessions are built around your unique lifestyle and objectives, ensuring every rep has a purpose.

2. Semi-Private Training (Up to 3 People)

Personalized coaching with shared energy and better value.
Semi-private training is a small-group format that includes up to three individuals training in the same time slot. Unlike standard group classes, each person in a semi-private session follows their own unique fitness program while receiving hands-on coaching from a dedicated trainer. This format provides the perfect blend of personal attention and shared motivation without the higher cost of solo sessions. It is an excellent choice for friends or colleagues who want to train together but still require individualized guidance.

3. Small-Group Specialized Classes (Women 35+)

Targeted programming for specific physiological needs.
Small-group specialized classes are designed for specific demographics or goals, such as our Women 35+ Strength & Conditioning program. These classes focus on building strength, improving mobility, and supporting bone health in a way that is safe and effective for the target audience. The group size is kept small enough to ensure expert instruction and individualized attention while fostering a supportive community. This format is ideal for those who want a welcoming environment tailored to their specific life stage and health needs.

4. Standard Group Training

High-energy community and structured coaching.
Standard group training is a class format where a coach leads a larger group of members through a unified workout. This is the core of the Colfax Strong experience, offering a high-energy environment where you train alongside people who push you to be your best. Coaches provide clear direction and feedback to the group, ensuring that everyone can perform the movements safely and effectively. This format is perfect for those who thrive on community energy and want a structured path to strength and endurance.

5. HYROX Training Classes

Race-specific preparation in a competitive group setting.
HYROX training is a specialized group class format focused on preparing athletes for the HYROX race. As an official HYROX affiliate, Colfax Strong provides structured, coach-led programming that builds the specific endurance and power required for race day. These classes are designed for competitive athletes, hybrid athletes, and first-time racers who want to train with a crew that matches their intensity. The group dynamic in HYROX classes is particularly strong, as everyone is chasing the same finish line.

6. Youth Personal Training

Individualized coaching for developing athletes.
Youth personal training is a one-on-one or small-group format designed specifically for teens aged 13 to 17. This program focuses on building a strong athletic foundation, teaching proper movement patterns, and developing confidence and discipline. Unlike general group classes, youth training is tailored to the specific sport and developmental stage of the athlete. It provides a screen-free environment where young athletes can learn to move with purpose and think like competitors.

7. Drop-In Sessions (Experienced Members Only)

Flexible access for experienced exercisers.
Drop-in sessions are a flexible option for experienced exercisers who are in town for a short period or need to maintain their routine while traveling. This format allows you to join a group class without a long-term commitment, provided you have the experience to follow the programming safely. Colfax Strong maintains a strict onboarding process for beginners to ensure safety, so drop-ins are reserved for those who are already familiar with strength and conditioning. This option is perfect for keeping your gains strong when you are away from your home gym.

Choosing the Right Group Size for You

The best group size for you depends on your primary goal, your budget, and your personality. If you need maximum accountability and individualized attention, one-on-one or semi-private training is the right choice. If you thrive on community energy and want a structured group experience, standard group training or HYROX classes will keep you motivated. Consider your schedule and how much coaching feedback you need to feel safe and confident in your movements.
