Intermittent Hypoxic Training (IHT)
Long recognised as a significant factor in the success of elite endurance athletes, altitude training involves various methodologies, each presenting distinct advantages and disadvantages. IHT is a contemporary method, offering huge benefits in an accessible and time efficient way, without the need to travel. The Cloud9 takes this one step further by bringing this innovative training method into your own home or gym space.
The Cloud9 altitude simulator delivers reduced oxygen through a mask, so you can train your body to use oxygen more efficiently. It’s incredibly convenient in comparison to all other options for altitude training, and the controlled environment and science-backed training plans mean that it can arguably deliver even better results!

Improved performance
IHT is typically undertaken in short sessions (25 to 60 mins), two to three times per week, often at medium to high intensity, with planned recovery periods.
Key benefits include:
-
New capillary production in muscle tissue for improved oxygen delivery
-
New muscle tissue development for increased power
-
Increased VO2 max for better oxygen availability
-
Higher cardiac output for improved blood flow
-
Increased mitochondrial activity for extra energy creation in cells
Many of the physiological adaptations can’t be achieved in any other way.


Start your Cloud9 journey today
Intermittent Hypoxic Training with the Cloud9 system can give you a competitive edge without disrupting your life. You sleep and recover at sea level, which preserves rest quality and allows you to maintain your normal routine. You only step into the low-oxygen environment for specific, intense workouts. These targeted, high-intensity sessions under hypoxia provide a powerful stressor that stimulates peripheral adaptations (in your muscles) to better utilise oxygen and clear metabolic byproducts. The Cloud9 altitude simulator offers the ultimate convenient addition to your home training set-up.
Case Study: Sam Howard
Sam is a 48-year-old former Kona qualified age group triathlete, now focusing on cycling. After completing a 6-week IHT plan with the Cloud9 she achieved a PB in a 10 mile TT of 20:54 and came 3rd in her first ever hill climb. She is currently the 7th fastest female in the country over 10 miles.
“What a season it's been – powered by altitude training, the best coaching, and consistent training. I've PB'd every distance l've raced this year – from 10-mile TTs to 50-mile TTs – and now there's even a hill climb in the bag!”
