How to Run Group Workout Classes That Keep Clients Coming Back

“If you want to go fast, go alone. If you want to go far, go together.” – African proverb

Fitness can be a lonely journey: headphones, screens, and selfies dominate the gym these days. But here at ABC Glofox, we know there’s a better way. Through group workout classes and training sessions, we help build the foundation for long-lasting bonds.

Meaningful social connections are essential to people’s health and longevity. Research has shown that being alone is as much a public health concern as smoking, obesity, and sedentary lifestyles. 

Warm fuzzies aside, group fitness classes offer so much more than simply filling that awkward Saturday morning time slot.

Bootcamp and functional training classes turn into powerful tools for retention. 

Small group personal training and HIIT become magnets for engagement.

Spin and circuit training transform your gym into a community.

However it looks, we know that more people are looking for workouts with a side of socializing. That means it’s more important than ever to offer fitness class programming that does just that.

In this article, we’ll explore the best group class workout ideas for every type of fitness business. We’ve got you covered, whether you run a boutique fitness studio or a traditional gym. We’ll also share tips on marketing your group workout classes and how to make sure people keep coming back.

Let’s lace up and get into it!

The Best Group Workout Classes to Offer in 2025

When it comes to fitness classes, your members want options. The best group workout classes not only mirror current fitness trends; they also reflect your community’s wants and needs.

Feeling stuck when it comes to group class workout ideas? Here’s a breakdown of group fitness trends to add to your class mix:

#1: High-intensity interval training (HIIT)

HIIT is a quick-hit, high intensity workout perfect for different fitness levels. Tabata-style training or AMRAP (As Many Rounds As Possible) offer variety and promote engagement, no matter who’s in the class and what their fitness levels are.

#2: Group strength training

These classes feature resistance-based movement using dumbbells, barbells, and bodyweight. They’re ideal for clients who want to build lean muscle and strength in a motivating setting. Group strength training rewards consistency and allows for progressive overload over time under expert supervision.

#3: Bootcamp fitness classes

Outdoor or indoor bootcamp sessions combine cardio, strength, and team-based drills. These classes will draw members out of their comfort zones and foster community through shared goals. Incorporate obstacle course elements and themed challenges to kick the experience up a notch!

#4: Spin classes

Indoor cycling is one of the best group workout classes out there. Loved for its blend of low-impact and high-intensity training, spin feels like a dance party on a bike! Ramp up the fun with themed rides or create a welcoming, competitive environment with metrics-based tracking.

#5: Yoga sculpt and Pilates

Yoga and Pilates give members the best of both worlds: body and mind techniques in perfect harmony. These small group workout classes focus on strength, flexibility, balance, and injury prevention. Yoga Sculpt ups the pace of traditional yoga and often adds weights, making it a new format for many members.

#6: Dance cardio

Fun and high-energy, these group fitness classes appeal to a wide variety of members. They combine music, movement, and cardiovascular fitness in an open, free environment. Zumba, hip-hop cardio, and Latin-inspired classes are popular versions of this trend.

#7: Mobility flow & recovery

Mobility and recovery classes are becoming increasingly popular, especially for athletes or older members. These sessions improve joint mobility, flexibility, and recovery. Instructors use foam rollers, stretching straps, and light bands to enhance these classes.

Bottom line: Bring these classes into your small group personal training or integrate them into your existing programs to add variety to your schedule. Don’t hesitate to rotate formats with the seasons or create hybrid classes based on interest.

Marketing Your Group Workout Classes

Creating top-tier classes is only half the battle. You need a solid marketing strategy to boost member attendance and retention. Here’s how:

SEO and blogs

Use basic search engine optimization strategies to make your classes discoverable online. Include key terms like “group fitness classes,” “bootcamp classes near me,” or “HIIT in [Your City].” Blog posts (like this one!) help position you as an authority. Consider writing blog content that targets your demographic’s specific needs—e.g., “Best Group Workout Classes for Moms in [Your City]”.

Social media promotions

Use Instagram Reels, TikTok, and Facebook to post class highlights and member stories. Video content works well for small group personal training or high-energy classes. Include behind-the-scenes footage and client testimonials to build trust.

Referral programs

Encourage members to bring a friend and offer discounted rates or a free month for referrals. Include social sharing incentives and track referral metrics through your ABC Glofox dashboard.

Community events and open houses

Host free trial classes, wellness workshops, or fitness contests to attract new members from your community. These events also build social connections—a key to member loyalty. Need ideas? Consider charity bootcamps, themed workout nights, or wellness speakers to expand your reach.

Free trials and challenges

Lower the barrier to entry with no-cost trials or low-cost entry points like 30-day challenges. Fitness challenges not only boost attendance but also create accountability.

Building Your Team of Group Fitness Instructors

Hiring the right talent 

Your instructors make or break the success of your group workout classes. 

Start by hiring certified trainers with strong communication skills and genuine enthusiasm for community building. Look for credentials from ACE, NASM, or ACSM, plus specialized certifications for specific formats like yoga or spin.

Training and onboarding

A great relationship with your team of instructors starts with onboarding. 

Invest in a comprehensive process that covers your gym’s culture, safety protocols, and staff expectations. Provide ongoing education through monthly workshops, certification reimbursements, and peer mentoring programs. 

This keeps instructors current with trends and techniques while building their confidence in leading different groups. 

Retention strategies

Competitive compensation, performance bonuses, and clear advancement pathways are top ways to keep your instructors happy. 

Recognize top performers publicly and give instructors input on class scheduling and programming decisions. Regular feedback sessions help address concerns before they become problems. 

Remember, happy instructors create engaging classes that keep your members coming back.

What is the most popular group exercise class?

Globally, HIIT and group strength training remain top choices. These classes have a broad appeal, especially when offered in 30-45 minute slots. Spin and dance cardio are still two of the best group workout classes to create that “can’t miss” energy.

Are group exercise classes worth it?

Yes! Group fitness increases revenue per square foot and improves member retention. They also offer structure, motivation, and social support for your members. Bonus: Group classes are often more affordable than personal training. 

What is the most popular group fitness class time?

Weekday evenings (5-7 PM) and weekend mornings (8-10 AM) tend to have the highest turnout. Analyze your class data to fine-tune when you’ll schedule group workout classes. Consider offering early bird or lunchtime express formats to reach different audiences.

How do I track the success of my group workout classes?

Keep tabs on the metrics that matter most for your group fitness classes. Start with class attendance rates—you’ll want to hit that sweet spot of 70-80% capacity consistently. Compare how long your group fitness members stick around versus your general gym members (AKA lifetime member value), and track the revenue each class generates per hour.

Here are other data points that deserve your attention:

• Class profitability (are you covering instructor costs and then some?)
• Equipment wear and replacement schedules
• How efficiently you’re using your studio space
• Member satisfaction through quick surveys and Net Promoter Scores

Pay attention to your waitlists, too—they’re goldmines for spotting which time slots are ripe for expansion. And don’t forget to track how many new members discover your gym through group fitness trials. 

This data helps you fine-tune your marketing efforts and shows you exactly which programs are driving real business growth.
