What types of classes do you offer?
We offer two main classes:
Strong & Lean - a time-efficient blend of strength training and Pilates for core stability, flexibility and lean muscle.
Bootcamp – a fun, high-energy mix of cardio, strength and core training that boosts your mood and fitness.
Where are your classes based?
Our in-person classes take place in Busby and Clarkston, in the Glasgow Southside. If the weather is dry, we take the class outside in my garden. We also offer online Zoom Strength/Pilates training classes so you can join from anywhere in the UK.
Are your classes suitable for beginners?
Yes! All classes are beginner-friendly, and we’ll guide you through each move with clear instructions. Exercises can be tailored and modified to suit your fitness level and any specific needs.
Do I need to be fit to start?
Not at all. Our classes are designed to help you build strength and confidence at your own pace. Whether you’re returning to exercise, starting fresh, or looking to improve your fitness, you’ll be fully supported.
What equipment do I need?
For Strong & Lean, we often use a resistance band or kettlebell. This is provided at the start and alternatives can be suggested. For Bootcamp, we use kettlebells and light equipment. We’ll guide you on what to bring or have ready for both in- person and online sessions.
What’s the community like?
We’re more than just a fitness class – we’re a supportive, like-minded community. You can join our WhatsApp group where we share healthy recipe ideas, motivation, and accountability between sessions. It’s a great place to stay inspired and connected!
How long are the classes?
Each class is designed to be time-efficient – around 45 to 50 minutes. Perfect for busy people who want maximum results without spending hours in the gym.
Can I try a class before committing?
Absolutely – we offer a free trial class for all new participants! It’s a great way to see if our style suits you.
