HOW DID YOU START YOUR CAREER IN THE FITNESS INDUSTRY?

My background in fitness started at university.

My poor diet, regular partying and all-round unhealthy lifestyle was taking its toll on my body.

I was struggling to focus on my studies, my skin was breaking out and I was tired of being tired.

I decided to make positive changes in an attempt to get healthier and happier.

It was a slow and gradual learning process, which lead to fitness going from a hobby to a passion.

I ended up finishing my degree and then moving into the fitness industry, working as a personal trainer full time and developing my blog on the side; until it got to the point where the blog could be my main career.

Now I work as a PT just because I love it.

My fitness regime has transformed over the years.

I have been through different stages and spent time focusing on a variety goals.

I have finally found my happy place where I combine heavy weight lifting with bodyweight and HIIT training.

I love getting progressively stronger through resistance training, but I also love the fact that you can do bodyweight circuits anywhere, anytime.

They are perfect for when you're short on time or always on the move.

I took the ELLEfit team through this quick, simple workout in the park.

No equipment is required and I promise you will get super sweaty.
