My name is Anthony and I am a certified personal trainer through “Elevated Learning Academy.” I first decided to become a personal trainer a few years ago, when I started Muay Thai. I found out every week they do a 5k run, and I remember being so nervous because I wasn’t sure I could do it. With the support of my group I did make it and 6 months later I ran my first marathon. It felt so great to accomplish something that I never thought I would be able to do, and I decided to get into an industry where I could help others feel the same way.

I started off my passion for training as a group instructor at Southpaw and have now been given the opportunity to focus on personal training. I don’t want people to see exercise and nutrition as a punishment but a tool to enjoy every day to the fullest. I’ll admit that when I first got into fitness, I approached it with the wrong mentality. I had to watch a motivational video every day just to get myself into the gym, because I saw it as something I had to do. Now I try to lead a good example by showing that I eat healthy (but still enjoy goodies from time to time ?) , exercise, push myself, and enjoy every second of it.

The one thing above all that gets results is consistency, so it’s important to me that everyone I work with enjoys their time and takes away something new to improve their skill. Cause who says sweat and smiles can’t happen at the same time?!?!


Beginner Boxing Coach “The Mongoose”

Hey, it’s coach Terence and I’ve been boxing for 7 years with the aim to go pro. I’ve had 21 fights and have gained experience from across Canada. Aside from boxing, I enjoy hiking, biking, and drawing. 

Back in Nova Scotia, I had a colleague who told me he used to train at Southpaw Boxing here in Calgary, so when I moved to Alberta I set out to find it and didn’t stop looking until I had. In 2020, I took up the job of coach upon request and I’ve been giving it my all since.


Kids Boxing Coach

Axel began his lifelong love affair with boxing as a teenager, somewhere in the late 80’s. A respectable amateur run, and a short stint in the semi-pro “Casino Circuit” in the 90’s followed. Since then, he has amassed a world of experience as a non-combatant citizen. Axel studied Elementary Education at the University of Calgary and has had success as a writer and publisher, as well as a myriad of other careers. 

As a dad of two and a former athlete, Axel understands the importance of getting kids moving, as well as keeping them interested in the sport. Having seen action in all aspects of boxing, from inside the ring, to coaching and judging, Axel has a wealth of knowledge and experience to help aspiring boxers and newcomers alike. He has been lucky enough to coach kids and beginners at Southpaw for several years, and plans to stay until he goes out like Mickey in Rocky III.”

Personal Trainer and Fitness Coach

Hello! My name is Liam Vig, I am one of the fitness trainers at southpaw family fitness & boxing and I’m also the pretty face you see at the front desk during the week. I also compete as an amateur boxer representing Goldenstars boxing team out of southpaw.

I began my journey in boxing on February 3rd of 2021 with the intention to one day compete at a high level. I had no idea what that looked like and how to go about it. With my only prior combative sport experience being 2 years of wrestling in high school. I committed completely, doing 2 classes a night. working my way through beginners all the way to advanced. I had my first fight on September 11th and have enjoyed every step of the way. As I’m writing this on December 9th, I’ve had 3 fights with a record of (2-1), competed in my first tournament and look forward to the journey ahead. Through it all I obtained a job at quite honestly my favourite place on earth! I hope I can help make it one of yours one day as well

My fitness journey has been a close companion to my athletic journey dating all the way back to my 10-year journey with soccer, leading into my 7-year career with football which saw me play semi professionally with the Calgary Colts. I obtained multiple accolades through my high school career including back-to-back all-star accolades, as well as a defensive player of the year and an overall mvp. Accompanied with my accomplishments within boxing, I know what it takes to reach your goals in multiple facets. And I look forward to helping you reach yours! With that being said, lets get you in here and get you training! Look forward to you joining our family.

Personal Trainer and Fitness Coach

Hi I’m Sam- a fitness coach and certified personal trainer through the International Sports Sciences Association. I began pursuing an active lifestyle as a way to manage anxiety and stress but I quickly fell in love with fitness once I saw how positively it affected almost every facet of my life.

One of my favourite parts of being a trainer is getting to see clients realize how much they are capable of when they zero in on their goals and start following a consistent program. I believe in a balanced approach when it comes to fitness. I’ll work with you to formulate a personalised program that suits your lifestyle and is sustainable long term, meaning you won’t just reach your goal, but be able to maintain your goal over time – because we’re in this for the long haul 😉 Outside of the gym, you can most likely find me outdoors. I love hiking, paddleboarding, skiing, and am an AIDA certified advanced level freediver.  

I am so grateful to have found this amazing community of supportive and dedicated individuals and look forward to helping you become the best version of you!

Specific focuses include:

Body recomposition and transformations

Hypertrophy and strength training

Functional fitness
