Whether you're chasing your first pull-up, training for a 5K, or just trying to touch your toes without wincing, the group fitness schedule at O2 Fitness Clubs has something perfect for you! But with so many options on the calendar, it can be overwhelming to know where to start.

That's why we've broken down our most popular group fitness classes by goal, so you can stop guessing and start sweating smarter.

Why Group Fitness Works

Before we dive in, let's talk about why group fitness is one of the most effective ways to reach your health goals. Studies consistently show that working out in a group setting increases:

• Motivation and accountability

• Consistency and attendance

• Effort output (you push harder when others are around)

• Overall enjoyment of your workout

At O2 Fitness Clubs, our certified group fitness instructors bring energy, expertise, and encouragement to every single class!

Best Classes for Building STRENGTH

If your goal is to build lean muscle, increase functional strength, or tone your body, these are the classes you'll want on your radar:

1. BodyPump™

Strength Rating: ⭐⭐⭐⭐⭐

BodyPump is the gold standard of barbell-based group fitness. Using light-to-moderate weights with high repetitions, this class targets every major muscle group in a single session. Expect squats, deadlifts, chest presses, and rows set to motivating music that keeps you moving from start to finish.

✅ Best for: All fitness levels looking to build muscular endurance and lean definition
⏱ Class length: 45–60 minutes
🔥 Calories burned: Up to 600 per session

Ready for more? If BodyPump starts to feel too easy, ask about BodyPump HEAVY — a more advanced variation that increases the weight and intensity to take your strength training to the next level.

2. Chisel

Strength Rating: ⭐⭐⭐⭐⭐

Chisel is the ultimate all-in-one strength class. Designed to develop strength, endurance, agility, and speed in a single session, this high-intensity full-body workout incorporates short bursts of plyometrics between each exercise to keep your body working at its peak. No two classes feel exactly the same, which means your body never fully adapts, and your results never plateau.

✅ Best for: Those who want a complete athletic challenge that goes beyond traditional strength training
⏱ Class length: 45–60 minutes
🔥 Calories burned: Up to 600 per session

3. Shred

Strength Rating: ⭐⭐⭐⭐⭐

Shred is an AMRAP (As Many Rounds As Possible) circuit workout that pushes every muscle in your body to its limit. Each class features 5 major circuits, each made up of 3 targeted sets (Upper Body, Lower Body, and Core) performed at maximum effort for 8 minutes. Circuits stack back-to-back with minimal rest to keep the body working and the heart pumping. Coaches provide form correction throughout, keeping every movement safe and effective. A bonus? Shred triggers EPOC (Excess Post-Exercise Oxygen Consumption), meaning your body keeps burning calories long after class ends.

✅ Best for: Anyone ready to experience serious metabolic conditioning and total-body strength in a high-energy group setting
⏱ Class length: 45–60 minutes
🔥 Calories burned: Up to 600+ per session
