Group Fitness and Boot Camps

Group workouts with NK Fitness are a FUN & VARIED way to get fit and healthy that are also SOCIABLE and COST EFFECTIVE.  We are highly experienced in getting the best out of groups of people ranging from public bootcamps through to Olympic Squads.

Our group fitness options include:

  1. Public Boot Camp / Outdoor Fitness Classes
  1. Corporate Fitness
  1. Small Group Personal Training
  1. Junior Conditioning Camps

Being part of group doesn’t mean you have to sacrifice quality with our underlying principles to winning group fitness:


The only competition is yourself...

A major drawback of group fitness can be the dread of having to keep up with everyone else, and feeling that you’re simply not fit enough.  We take this worry away from you buy structuring sessions in a way that simply has you competing with yourself – no comparisons with others.

And whilst we will always encourage you to get the best from yourself, you have the freedom to work at the intensity which best suits you.

Never neglect quality movement for quantity

Quality of movement is more important that quantity which is why all of our sessions focus upon neuromuscular control during warm ups and there’s a high level of individual coaching throughout every session.  We don’t just want you to do a lot, we want you to do it well!

Keep it broad

Most clients have a very narrow exercise base, i.e. they perform the same training for most of the time.  This can lead to movement deficiencies and predispose them to injury.  Our group fitness sessions are movement based rather than muscle focused and consist of exercises and challenges for all aspects of fitness across all major planes of movement.

Meet Individual needs

We cap our sessions at a maximum of 20 to ensure that you don’t get lost in the crowd, by coaching you all the way through every session.  Each exercise is offered with an alternative for those who want to either simplify it or want more of a challenge.  And if there’s something specific you want to work then all you have to do is ask – we’ll be happy to work it in for you.

Highly recommended!
I teach, perform and have competed professionally in Pole & Aerial Fitness but after hitting a plateau in my training I needed that extra push to reach the next level, David has been brilliant at developing a personalized plan to help me further progress, achieve my goals, and complement my current training. PT sessions with him are always something to look forward to, tough but fun, and most importantly gets results! My strength and flexibility have vastly improved, which has been of great benefit to me in my pole and aerial work. Along with his nutritional advice and recommended changes to my diet, I feel more energized; I’ve lost body fat and increased muscle mass. Win win!

I have been training with Nath and NK Fitness regularly for three years now and have nothing but good things to say.

Sessions are well thought out and individual drills/exercises are effectively demonstrated to ensure you get maximum benefit from your training time.

Nathan's sessions offer great variety, rarely are two sessions the same which really helps to keep you engaged and working hard!

Nathan is hugely knowledgeable and will always offer support and advice in all aspects of your training.

His professional and friendly approach ensures that you both work hard and enjoy your sessions
