THE ALTA METHOD
BUILT FROM EXPERIENCE. DESIGNED FOR LIFE.
Led by Lee, former Royal Marines Commando Physical Training Instructor, and Charlotte, behavioural psychologist and senior NHS leader, ALTA Method brings together decades of experience in physical performance, behaviour change and wellbeing.
Built around discipline, balance and adventure, ALTA combines training, nutrition, recovery and behavioural development to create stronger, more resilient and capable people.
Inspired by Mens sana in corpore sano — a healthy mind in a healthy body — the philosophy goes beyond fitness.
Build the body. Strengthen the mind. Create habits for life.
LEE CALDER
FOUNDER, PT LEAD
COACH. COMMANDO. PERFORMANCE-DRIVEN.
Lee is a former Royal Marines Commando, Physical Training Instructor and performance coach with over 25 years’ experience developing people through structured physical training and coaching.
His philosophy is simple: build stronger, more capable people.
From military personnel and private security operatives to athletes and individuals simply wanting to perform at their best, his approach is built around mastering the fundamentals, developing confidence and creating the discipline and habits that produce lasting results.
A qualified British Weightlifting Coach, Mountain Leader, Swimming and Ski Instructor and ABA Boxing Coach, Lee brings extensive experience across strength and conditioning, endurance, combat sports and outdoor leadership. His martial arts background includes a black belt in Karate and many years of Judo and Brazilian Jiu-Jitsu, alongside delivering practical women’s self-defence training.
He has also tested himself in demanding endurance events including the Mont Blanc Vertical Kilometre, Transalpine Run and Marathon des Sables across the Sahara.
His coaching is clear, disciplined and purposeful. No unnecessary complexity. No training for the sake of training. Every element has a reason.
Above all, Lee believes good coaching should eventually create independence — giving people the knowledge, confidence and capability to take ownership of their own performance.
Build strength. Build confidence. Become capable.
CONFIDENCE, CLARITY & LASTING WELLBEING
BEYOND FITNESS
THE MOST IMPORTANT CHANGE IS CONFIDENCE — IN YOUR BODY, YOUR MIND AND YOUR OWN CAPABILITY.
ALTA is about more than getting fitter. It’s about developing the strength, knowledge, habits and confidence that carry into everyday life.
The goal is simple: to help you become stronger, more capable and increasingly independent — equipped to maintain your progress long after the programme ends.
Results matter. What you become along the way matters more.
"I couldn't find a programme that truly understood my needs until ALTA Method. Their tailored approach has transformed not just my body, but my entire outlook on health."
Oliver Hartman, ALTA Method Client
