Core Essentials

Four weeks to a stronger, more coordinated core.

  • Do you dislike the gym or struggle to find the time?
  • Do you wish you had a stronger, more reliable core?
  • Do you struggle to make time for yourself?
  • Not sure how to reach your fitness goals?

If this sounds like you then Core Essentials was made with you in mind. No matter what you do in your day to day life you need a core that supports you 24/7. You need a flexible training plan that fits with your schedule.. and ideally is completely portable and equipment free.

If you have a desk job, don't have (or want) a gym membership, don't prioritise your training above all else... then you are just like me! I am the imperfect PT, but I get my training in and I love what my body is capable of! If you want to enjoy your body, feel strong and pain free then keep reading...

When you think core, do you think crunches? Core Essentials is here to change that. Core Essentials is a core workout programme that is 100% crunch and sit up free. That's right - equipment free, sit up free, but seriously effective.

How does Core Essentials work?

How does a 4 week course transform your core? By using effective, specific exercises that you can keep doing anywhere you are.

The course has three parts:

  1. The Theory: Understanding your body reassures you that you're looking after it the best way you can. The exercises you will cover work a range of muscles, by the end of the course you will understand the why and the how behind each of the exercises and flows in Core Essentials - and when it comes to training knowledge is power!
  2. Scheduling Call: Not sure how you are going to fit everything in? No problem. Before you start the workouts you'll book in a call with Seonaidh who will talk you through when and how to get the most out of the workouts. You will have instant messaging contact with Seonaidh for the whole course so you can get your questions asked and answered in real time!
  3. The Workouts: Each week you get 3 workouts that take you through the nuances of Technique, Turns, Twists & Testing your core. The workouts gradually increase in difficulty, but you always have the option to repeat a week. Not sure you've nailed week 2? Do it again before moving on. You have lifetime access to the course so make it your own!

That all sounds amazing - But what if you struggle?
