Absolute game changer. Used the Box Altitude system in preparation for the Mongolia Bike Challenge. Awesome recovery and altitude acclimatization with noticeable performance gains that lasted for months.

We have had climbers preparing for base camp, to Ironman athletes training for their next competition in the space. It's a great way to push the human body forward and break those road blocks that hold you back from the next step.

After sleeping at altitude for 3 months I noticed a significant improvement during sustained high intensity efforts. Performances in races and rides went up and my awareness when in the red zone was a lot clearer. Sleep quality and heart rate variability both improved as my body adapted to the altitude.

During my training I consistently monitor my heart rate and lactate levels, especially during intensity session. Since using Box Altitude I've noticed I've been getting stronger and faster, through being able to sustain higher intensities and lactate levels at lower heart rates and for longer periods of time. I was also surprised I am sleeping well even at the higher altitude (<2200), which was really important for me.
