Jim Summersby - PerformancePro coaching

Meet Jim Summersby, PerformancePro strength and conditioning coach. Jim’s true passion is in studying and realising the potential of human performance. Not surprisingly, this makes him a great fit as he joins the PerformancePro team.

We caught up with Jim in between his client sessions at PerformancePro to find out more about him.

Life before PerformancePro

Jim Summersby was born and brought up in South East London. After graduating from Brunel University with a degree in sports science, Jim moved into a career in advertising. This move lasted for 18 months before he decided to travel the world,

“Travelling gave me time to reflect on what my true passion was and that was geared towards human performance.”

Jim landed in Australia and took a course in personal training. After qualifying, he spent just over a year working as a trainer at various facilities across Melbourne, before moving back to London in 2015.

Jim has been working fulltime as a personal trainer in central London ever since, completing his MSc in Strength & Conditioning along the way. His internship at an academy for a championship football team also led to his part time role at the club as the U9s-16s strength and conditioning coach.

Jim Summersby and PerformancePro

We’re always interested to find out why our coaches want to work at PerformancePro. For us knowledge (and practice) sharing and continuous learning are key to our ethos, so it was great to hear Jim’s perspective on this too,

“What initially attracted me to PerformancePro was the level of education held between the coaches. It is very rare to find a facility in which the trainers have such a high level of education. This of course means nothing without practical application but after following PerformancePro for a few years on various social media channels it was clear to see the coaches did not just have theoretical knowledge but also the fantastic ability to apply it.

“What I like most about PerformancePro is that while most facilities shout the loudest about what they are doing PerformancePro quietly and effectively goes about its business, producing consistently high level results. There is a clear focus on upskilling and educating coaches.

“What I enjoy most about my working day are the interactions and relations that we build with our clients. I enjoy opportunity to engage them in the learning process so they can take ownership of their goals and make good decisions in their day to day life.“ 

And away from the gym?

Away from the gym, football consumes a very big portion of Jim’s life!

“Luckily I have a very understanding and supportive wife who at the time of writing is happy to share me with the game. Let’s hope this continues.”

Jim’s own fitness

The focus of Jim’s approach to his own fitness has evolved over time,

 “Within my own training I enjoy feeling “athletic” and stopped chasing aesthetic goals many years ago. I enjoy lifting heavy, sprinting, jumping etc. These are things that I teach regularly, I am a firm believer in practicing what you preach so like to ensure I keep my own ability within these high.”   

Top 3 fitness Do’s and Don’ts?

  • Be consistent
  • Master the basics
  • Take ownership of your goals
  • Don’t look for quick fixes
  • Don’t copy everything you see on social media
  • Don’t over think the process


For inspiration Jim reads, listens and watches a wide range of books, audiobooks, podcasts and documentaries, in a variety of different areas.

“Lessons and concepts can be learned and applied from many different settings, so I try to keep an open mind on where I look for information. Some of the best lessons I have learned have not come from fitness-related textbooks but through seeking out information and stories about those who have mastered their craft. Regardless of the industry you are in, success always leaves clues.”
