As you know everyone is different, has different body, conditions, schedule and goals. We will be more than happy to share with you more benefits you will experience in our initial consultation call.

Hundreds of our clients have gone through this journey. If they can do it, so can you.

Our programs is not a 30 days challenge. Is not a 12 weeks or 16 weeks program. We don’t charge you hourly like personal trainers or nutritionists and we don’t treat you like a number in our program. The Spartan Coaching Program is here for you for life. We take a one-time investment for a lifetime membership with no annual charges.

There are 2 reasons we offer a lifetime membership:

 1. Everyone is different and requires a different timeframe to achieve their goal. When we provide with a lifetime membership you don’t need to worry when you have to pay or when your program will expire. We are there for you until the end and we truly care about your results. That’s why we have so many testimonials which you can see here https:// www.xeniosfitenss.com/results

 2. You simply educate you! As our clients say “Xenios doesn’t just give you the fish, he teaches you how to catch the fish”. We believe that at some point you will be so advanced with fitness that you will no longer need us, so giving you a lifetime membership it’s our guarantee that this is the only program you will need in your life.

That’s exactly what we are looking for and what 90% of our clients are.

Our approach is fully personalised to your schedule, either you constantly travel, either you go to restaurants multiple times per week, either you have a family, kids and work 12 hours per day.

We design a program that is exactly for you, is sustainable and gets your results. We will be more than happy to talk with you regarding this in our consultation call.

Hundreds of our clients have gone through this journey. If they can do it, so can you.

Not at all! We provide 3 options to our clients in regards to the personalised workout program.

Option 1: If you want to train at home, you simply send us a picture of the equipment you have available and we will design the program based on that. If you don’t have any equipment we will design the program based on your bodyweight, some cheap resistance bands or even with your furniture at home.

Option 2: If you have a gym membership, we will ask you to send us the name of your gym, location of your gym and we will do our research on google to see exactly how your gym looks like so we design the workout program according to the equipment that is available to you.

Option 3: We can design something hybrid. Something that can combine home + gym membership if you want to avoid going to the gym.

If you are travelling, staying at hotels, moving to different cities and gyms all the time, or want to workout outdoors we can still adjust the plan to any situation that you want. The workout plans are designed to your lifestyle and needs.

If you watch the interviews at our results page on www.xeniosfitness.com/results you will read many success stories where our clients did not go to the gym and worked out at home or throughout their extensive travels.

No, there is no prior training experience required. It does not matter if you have never done resistance training before or even exercised before; we cater for all different levels of experience and will develop a plan that is suitable for your needs.

If you never done any exercises before our Xeniosfitenss app will help you as it shows you exactly videos step-by-step how to do the exercises so you have the right form, technique and also get educated on what each exercise is targeting.

This is what makes us different. We work hard to tailor everything we do with you to your unique lifestyle, goals and personal challenges.

The Xeniosfitness app has full video explanations and written instructions on how to perform each exercise in your programme. We will tell you what muscle groups you’re targeting so you know what you need to focus on. We also ask you to provide us with videos of yourself performing any exercises you are unsure about so we can offer feedback and advice on how to correct your form and get the most out of the exercise.

Yes, we currently have four different programs. The Spartan Coaching Entry, Starter, Premium Advanced and Elite.

On the call we will have we will help you to make the right choice for you, discuss the duration, adjustments that you might need for the option you will choose and the investment.
