He thoroughly believes that we should strive to perform as good as we look and so massively enjoys Strength & Conditioning based programs with huge emphasis placed on Olympic lifting and the Powerlifts, while also incorporating strongman training, High Intensity Interval sessions and old school body building.

Jim has worked with several rugby teams and is an avid fan of rugby league, playing it during his time in the infantry and rugby union whilst away in South Africa.

Lisa Ashcroft
Lisa AshcroftCoach - 5S Fitness Ltd
Lisa has spent years progressing her training and nutrition, constantly striving to develop programmes that are specifically designed to meet her every need and goal. Over the many years of trialling different training methods and diets she has found a passion for Strength training and metabolic conditioning, knowing that in order to stimulate changes in the body, we need to work to high intensities and take ourselves outside of our comfort zones.

She has also developed a keen knowledge of nutrition and how to best develop nutritional programmes that are tailor made to suit each and every client. Diet and nutrition is not about stripping away as many calories as we can, it’s about finding the right balance that is going to help you achieve your goals, while also being sustainable long term.

If you’re looking for a coach that is not only going to make sure that your training is of the highest standard, but will also ensure that you maintain a healthy and nutritious diet and lifestyle, then Lisa is the coach for you.
