The simplest way to rebuild your cardiovascular fitness, metabolism, and physical resilience using The Cardio Shed.

You don’t need to understand the biology or decide what to do. Each session is selected and delivered for you, using precise training signals that force the body to adapt, and the programme is scalable depending on how much time you can commit.

Two hours per week is enough to improve cardiovascular health.
Four hours per week delivers the full system and the deepest level of change.

No wasted effort. No burnout. Just steady, measurable progress.

Two sessions per week — Minimum Effective Dose

These two sessions deliver the core metabolic and cardiovascular adaptations.


Session 1 — CAROL + Echo Bike Intervals

Metabolic Upgrade Session

This session improves your body’s ability to produce and use energy.

Short, maximal sprint efforts trigger mitochondrial adaptation.
The intervals that follow train your heart, lungs, and muscles to deliver and use oxygen efficiently under load.

This improves:

  • VO₂max
  • Energy production
  • Lactate clearance
  • Cardiovascular capacity

Session 2 — CAROL + Ramping Threshold Cardio

Efficiency & Endurance Session

This session improves how efficiently your body sustains effort.

After activating the metabolic trigger, controlled ramping work trains your system to operate cleanly at higher output levels.

This improves:

  • Lactate threshold
  • Aerobic efficiency
  • Stamina
  • Cardiovascular stability

Together, these two weekly sessions rebuild your cardiovascular engine.

Total time: approximately 2 hours per week

Most people experience clear improvements in energy, endurance, and fitness within the 12-week period at this level alone.


Three sessions per week — Recommended Level


Session 3 — Longevity Conditioning

This session restores structural balance and nervous system stability.

It improves:

  • Posture
  • Movement quality
  • Joint integrity
  • Recovery capacity

This ensures your body can support and sustain the cardiovascular improvements.

Total time: approximately 3 hours per week


Four sessions per week — Optimal Level

Session 4 — Alternating Weekly Block

This session alternates between two specialised interventions.


Week A — Hypoxic Hill Climb + Hyperoxic Flush

This session improves your body’s ability to deliver and use oxygen efficiently.

Controlled low-oxygen work stimulates adaptation.
The oxygen flush that follows accelerates recovery and cellular repair.

This improves:

  • Oxygen efficiency
  • Endurance capacity
  • Mitochondrial function

Week B — Alpha-Wave Recovery Session

This session focuses on nervous system recovery.

It improves:

  • Recovery speed
  • Stress resilience
  • Nervous system balance
  • Overall adaptation

This allows your body to fully absorb the training and rebuild stronger.


Total time: approximately 4 hours per week

This is the optimal level for full transformation.


How the Programme Progresses

The programme builds gradually over 12 weeks.

Early sessions establish the signals.

As your system adapts, capacity increases, and each session builds on the last.

You don’t need to manage or adjust anything. You simply attend your scheduled sessions.


Coaching & Support

Each week includes guidance on:

  • Recovery
  • Sleep
  • Nutrition
  • Breathing
  • Stress management

These factors ensure your body can respond fully to the training.


Expected Outcomes

By the end of the 12 weeks, most clients experience:

  • Improved cardiovascular fitness
  • Increased energy and endurance
  • Faster recovery
  • Improved metabolic health
  • Better movement and posture
  • Greater resilience to stress

Daily life feels easier. Physical effort feels cleaner. Energy becomes more reliable.
