WELCOME TO THE TRAINING LAB SOUTH BOSTON

Our Services

At The Training Lab, we believe fitness should be challenging, effective, and—most importantly—accessible to everyone. Our expert-led classes are designed to help you build strength, improve conditioning, and feel your absolute best, no matter where you’re starting from. Check out our class line up! Note: Our TRAIN and SWEAT classes are priced differently than our STEP and LIFT formats due to smaller class sizes and more individualized attention.

  • Small-group strength training to build muscle and confidence.

  • High-energy conditioning workouts focused on power, speed, and agility to complement TRAIN days.

  • Group dumbbell and kettlebell strength classes designed to sculpt and strengthen.

  • A fun, rhythm-based step aerobics class that gets your heart pumping.

  • Personalized coaching to reach your individual goals.

New to fitness? No problem. Our intro/beginner classes ensure that everyone—regardless of experience—feels welcomed and supported from day one. Whether you're looking to lift heavier, move better, or just feel stronger, we’re here to guide you every step of the way.

Join us and experience fitness without the intimidation—just expert coaching, great energy, and real results. Check out our intro class offerings below.

Let’s get stronger together. 💪
