The foundation of our programming is based around our 3 pillars of fitness principle.
Over the course of our training cycles and across every class, we aim to develop our athletes in every pillar to deliver well balanced fitness and injury resistance both inside and outside the gym.
Strength & Power | Speed & Endurance | Mobility & Balance
Strength & Power
Including strength and power work in your training is crucial to achieving many fitness goals. It has a huge impact on building muscle, losing fat, and improving your ability to train for longer. Our CrossFit, Stronger, Delta ∆, and Athletica classes include a variation of strength and power movements every week to keep your training balanced.
Speed & Endurance
Our classes are designed to develop our athletes ability through varied lengths of workouts. Short hard sprints in our Interval Weight Training programme help athletes develop capacity across short bursts. Classes like The Thread, use variable intensities and pacing to build capacity across longer time periods. With measured outputs included throughout our cycles, you can track your progress and see how much you have improved.
Mobility & Balance
Mobility and balance are often the most overlooked aspect of an Athletes training. Everyone wants to lift heavy and get sweaty. But we help you improve your movement and mechanics too. From our specific Motion classes, to the functional body building included in all our programming we help you move better. This directly translates to the other pillars of fitness.
Team
You can’t have amazing members without great coaches
That’s why we have highly qualified, experienced and well-educated coaches. Importantly they are full time with sick-pay, pensions & holidays. There is real career progression as Gymnasium expands. They all go on regular courses across a range of fitness & nutrition specialisms and bring their knowledge back top the wider team and members.
New coaches all go through the Academy, our coach development program. We are recruiting and training coaches with a wide range of skills and backgrounds who receive a series of practical workshops, videos and our handbook to show them how we coach at Gymnasium. They then join classes to shadow our full time Coaches before starting to lead classes themselves.
