Amazing Course & Career

After having a long-term passion for fitness and having built up her fitness Instagram page (@angfitpt) following to nearly 60k, Angel was getting messages constantly regarding her routines and workout posts. She decided to enrol onto OriGym's Personal Training Diploma and since has also started her Advanced Nutrition Qualification to offer her followers expert, qualified advice. 

Before I started the course, I was a lover of the gym, but unsure where I wanted to take my career. I was at university studying something I couldn’t see myself doing. That was until I found OriGym. I wanted to do the course so I could learn more about a passion of mine and eventually turn it into a career. I wanted the knowledge to turn my passion into my day to day life. I am now going to start working in a gym as a personal trainer, building my own business and hopefully continue to study around the subject too. I’m excited for what the future holds!

The Best Course Provider

Jessica is a track sprint cyclist specialising in the keirin and has represented her country at the Asian Games and recent 2020 Olympics. Jessica choose OriGym to study her Personal Training course and specialist Level 5 in Nutrition course after being recommended by friends.

From a sports background I have always been passionate about sport, for every elite athlete passing on knowledge and expertise is a good continuum from what I've already achieved. Although this is starting something new, it's also building on something that I already have. 

I reached out to friends who have done similar courses and OriGym was mentioned as the course to go to. After I enquired, Michelle called the next day and was really organic and genuine in our conversations, whereas other providers sent a generic email where I still had to do more research myself.

As an olympian a mission is to always pass on experience and knowledge. I'd look to eventually have my own company and client base to really pass on my passion and maybe even help create a new olympian in the future!

Invaluable practical experience!

Before OriGym Ramnik was facing redundancy after a 10-year career. With an existing interest in health and fitness, Ramnik knew a role helping others to reach their goals would suit his personality and ambition. Searching online, he signed up to the Level 3 Gym Instructor and Level 4 Personal Trainer course. 

I absolutely made the right decision to choose OriGym! I’m very grateful for their continued support and their amazing tutors. They are really encouraging, helping to build your confidence to succeed. OriGym’s approach to flexibility encouraged me to study in my own time through online assessments and tutorials. Perfect for a busy parent juggling responsibilities.

My career since has gone from strength to strength. I set up my own brand whilst studying, creating a home-based studio where I train my clients. I also work as a Group Fitness Instructor, have set up my own HIIT fitness event and work with local academies encouraging children to enjoy exercise as part of a healthy lifestyle.

Fitness Instructor & Personal Trainer

I love my new career!

Before joining OriGym, Sue worked in a gym as a Membership Sales Advisor. Many new members asked if Sue would be willing to train them, but as she wasn't qualified, she had to keep turning them down. Researching several companies, Sue enrolled on OriGym's Personal Training Diploma and has never looked back!

I researched many fitness courses but kept coming back to OriGym. I felt a good vibe from the team and the owners Luke and Steph are friendly & down to earth. I loved how involved they were in the courses! The course itself was AMAZING! The staff and teachers were fantastic, I really felt that they cared about me and my progress, going above and beyond what I had ever expected from them.

I’m now a confident Personal Trainer working for an international gym chain. The future looks so bright for me; I’m even enquiring about doing a season on a Cruise ship as part of the Royal Caribbean fitness team! OriGym has helped to make my dreams come true.
